Abstract. This study aims to synthesize acaricide in the form of a new eco-friendly model by using laser technology to prepare a
colloidal solution of titanium dioxide after detecting the presence of a high percentage of resistance to the traditional acaricides
used to treat Ticks and tick-borne diseases. The slope of mortality, lethal concentrations for 50 per centLC50), 90per cent
(LC90), and 9per cent(LC99) with 95per cent confidence interval (CI), and resistance ratios were determined using regression
graphs of probit mortality of larval ticks plotted against log values of increasing concentrations of amitraz (RR50, RR90, and
RR99). The mean RR50, RR90, and RR99 values varied from 0.83 to 1.52, 0.97 to 2.66, and 1.10 to 4.19, respectively,

INTRODUCTION
Th ree-host tick Hyalomma anatolicum (Acari: Ixodidae) is widely dispersed in Iraq, infecting cattle, buffaloes,
sheep, and goats, as well as parasitic protozoans like Theileria annulata, T. buffet, and T. buffet1]. Tick infection
results in low-quality hides because t of bite marks generated by Hyalomma's longirostrate mouthparts, lower weight
growth,amilk supply productivity and increased calf mortality [2]. Ticks and tick-borne illness management costs
for Iraqi livestock are up to US$498.7 million per year [3-7]. H. anatolicum, the most widespread species in Iraq,
especially Thi-Qar, is reported among 10 Hyalomma species. [8]. An essential instrument for the worldwide control
of ticks were Organophosphates (OP), synthetic pyrethroids (SP), amitraz (Am), and macrocyclic lactones are
examples of chemical acaricides (MLS). However, its widespread and repetitive use has resulted in tick resistance,
toxicity, gastroenteritis, and environmental deterioration [9]. Adaptation to synthetic acaricides in Rhipicephalus
microplus, a single-host animal from Punjab, has been described in several articles, including OP. [10], SP [11], Am
[11], and ivermectin [12]. However, reports of acaricide resistance in H. anatolicum from Iraq are few. [13-15]
Because of the time limit of three-host tick exposure, resistance to acaricide is relatively low in comps compared to
host ticks [11]. In the larval biomass test devised by Stone and Haydock (1962) [16], larvae in a paper packet treated

with technical acaricide were used. The Food and Agriculture Organization (FAO) has now adopted this approach
has the FAO Larval Packet Test to measure tick populations' vulnerability to acaricides (LPT). LPT is being used in
numerous countries to test ticks for OP, SP, and hydrocarbon resistance, but not for amitraz because no amount of
the drug response has been observed. [17]. Accordingly, Miller et al. of the United States Department of
Agriculture, Cattle Fever Tick Research Laboratory (USA) devised a modified LPT for assessing amitraz resistance
in R. microplus, which was then experimentally used by several authors. [18, 19] The investigation was started in
order to calculate the resistance level of amitrate in H. anatolicum ticks in Thi-Qar, Iraq locations using the modified
LPT.
NANOPARTICLES
TiO2 has been researched for a long time. Due to its extensive usage in photo catalysis, optical materials, dye-
sensitive solar cells, and battery sectors [20-24], titanium dioxide is a fascinating family of inorganic solids in a
broad variety of common and high-tech applications. There are three kinds of crystalline TiO2: rutile, anatase, and
brookite, with rutile serving as the thermodynamic stabilizer [25]. liquid (LAL) laser ablation, may lead to
Ethereum conditions and the production of novel nanostructures, pulsed laser removal of metal targets has received
a lot of interest in recent years. [26-30] Composition that is liquid The radiative expansion of the plasma and its
interaction with surrounding media, as well as the locally super high-temperature plasma (approximately 6 000 kb)
and high pressure ((approximately 1 Gpa) the solid-liquid interface, are all produced instantly when a pulsed laser
beam with sufficient energy irradiates into a transparent liquid on a metal target and is quick to tap one pulse about
the same beat. The entire procedure takes 1 second. As a result, laser removal of metal targets in liquid settings
migrespecificationain particular nanomaterials hard to acquire using traditional methods. [31−34].
LAL effectively synthesized rutile TiO2 nanoparticles of a titanium plate in one step at room temperature in distilled
deionized water, according to this report. We performed laser ablation of Titanium Target in water and stored
powder on a solution to generate a highly biological photocatalytic colloidal solution that leads to a concentration
range that is later evaluated for semi-lethal concentration. The surface topology structural characterization of the
deposits was studied using atomic force microscopes (AFM).
EXPERIMENT
Laser ablation of a high-purity titanium target immersed in water at room temperature produced titanium oxide NPs.
A schematic overview of an experimental system configuration is shown in Figure 1. Titanium marks r placed on the
bottom of a 2ml liquid glass sketched was etched laser with wavelength of 1064nm, 7ns, and a repetition frequency
of 1Hz is used to irradiate the Titanium target. To ablate the laser energy of Titanium, a total of 80mJ/pulse was
used for 5 minutes. The laser beam was focused on the titanium target using a 50mm focusing lens. The ablated Ti
NPs were examined using an atomic force microscopy (AFM) model (SPMAA 3000 Angstrom Advanced Inc.
USA).

MATERIALS AND METHODS
The location, geography, and climate of the research area Thi-Qar Governorate is in southern Iraq, north of Basrah
Governorate, and has internal boundaries with Missan, Muthanna, Qadissiya, and Wassit Governorates. The state of
thi qar is located in southwest Iraq, between latitudes 12.30°N and 12.32°N and longitudes 45. °E. It covers 50,362
square kilometers and is situated between 180 and 300 meters above sea level. The state's average rainfall ranges
from 340 to 512 millimeters, with 120 millimeters in the north and 112 millimeters in the south. Water bodies cover
900 square kilometers, with a length of 120 meters and a width of 110 meters.
Collection Of Ticks
Female ticks that were completely engorged and had fallen were gathered from dairy sheds in al-Nasiriya, al-Rifai,
al-Suq, al-Chibayish, and Al-Shatra in Thi-Qar state's southern regions. Despite the experimental recurring use of
amitraz for tick management throughout the year, tick infestation was identified as a serious concern in dairy cows
in several areas. In cattle shelters, every conceivable tick hiding spot was extensively investigated (cracks and
crevices, loose bricks, and other detritus on the ground). Ticks were collected in plastic vials and covered with a
muslin cloth to enable air and moisture exchange before being transferred to the Entomology Laboratory,
Department of Veterinary Parasitology, Veterinary and Animal Sciences Institute, Thi-qar. The
susceptibility/resistance status in field ticks was determined using the colony of acaricides susceptible reference
IVRI-II line of H. anatolicum.
The Ticks' Preparation
Using a microscope, the ticks were identified as Hyalomma anatolicum. Sen and Fletcher's identification key (1962).
The implanted female ticks were washed in water, drained, and ovipated on 5-cm plastic Petri plates in a moisture
cabinet at 28°C and 85.5% RH. Incubation of the eggs took place under the above-mentioned hatching
circumstances after they had been collected, mixed well, and weighed (20 days). A step-by-step guide to the process
is provided here. An experiment with live larvae aged 14 to 21 days was conducted.
Bioassay
The amended LPT was performed in accordance with Miller et alprocedures. .'s (2002). For the production of
various working concentrations of amitraz, To accomplish serial dilution in two parts, amitraz (Taktic® 12.5 percent
EC, MSD Animal Health, India) and olive oil (OO), SigmaAldrich, were diluted to a two-part extent (Sigma-
Aldrich, St. Louis, MO, United States). There were three replicates for each dose with a negative was recorded in
controller (diluents only). The 8 bis 9 cm nylon TChE After receiving 0.6 mL of each dilution attenuators, it was
allowed to evaporate for 2 hours The fabric is a Type 2320 from Cerex Advanced Fabrics in Pensacola, Florida.
After drying, the experimental panels were folded in half and clipped together using metal clips to keep them in
place. Deli No. 8532 (Round Clips) of the Deli Group Co., Ltd. in Ninghai County, Zhejiang Province, China. On
the sides, there is a packet was placed. Each packet was filled with around 100 larvae, and a third clip was placed on
the top. The larvae packages were kept in 24 hours at a rate of 28 ± 1oC, and 85 ± 5% RH. The packages were then
opened and the number of living larvae and dead-rate larvae tallied. Larvae, who moved but didn't move their legs,
had been considered dead.
Statistical Analysis
For probit analysis, Polo-Plus was utilized (Lutilisedftware 2004). The Polo-log-probit Plus model produces a
regression line that illustrates the association between the proportion of larvae that die and the acaricide dosage used
The chi-square test was used to analyze the deviation in the proportionality of log-probit extracted features
(Robertson and Preisler 1992 With a 95 percent confidence interval (CI), the toxic concentrations at 50 per
centLC50), 90 percent (LC90), and 95 paper centLC99) were computed. The variance and covariance of each slope
and intercept were used to calculate resistance ratios (RRs).

RESULTS AND DISCUSSION
The color of the solution, which indicates the synthesis of Titanium Oxide Colloid Nanoparticles after laser ablation
of the Titanium target is changed from colorless to candid white as seen shown in Figure (1, b). Figure (2) depicts
3D Two-dimensional and three-dimensional using atomic force microscopy known as (AFM). Titanium oxide NP
images burning in 1m scanned water with a scanning range of 1m per 1m. Its average diameter and height of grain is
about 81.04 nm. For TiO2 thin film, and rm ruggedness values are (2,27 nm). AFM images show that particles with
various sizes have diverse morphologies. Fig. (3, a) illustrates that JSc V is a short circuit current density as an
illuminating energy function before and after the deposition of titanium oxide nanoparticles, at low luminous power
levels, we observed a linearity behavior with a power rise. However, with high lighting power, Jsc has a saturated
behavior that explains, after titanium oxide NP swore 40.2 was deposited, the highest (Jsc) was 40.2. (mA cm-2).

Now we have obtained the open-circuit voltage (Voc) of 630mV) which is millivolt and also the amount of electric
current in the impeding circuit which is (current density (Jsc) of 40.2 mA/cm2) and the packing factor (FF=0.7) as in
the figure (4. a, b) where the energy can be calculated from the cell before and after the deposition of titanium
particles. It is most likely that the packing factor is high is the excessive shunt impedance and the short circuit
current density may be due to the effect of photons that are saturated in the depths of the widest part of the silicon
Figures (4 a, b) and (4 c, d) show the output power which is the power generated by the cell under simulation
(AM1) versus the resistive voltage based on the loading impedance before, After the deposition of titanium oxide
particles, it was observed that after the deposition of titanium oxide particles, the efficiency of nanoscale titanium
increased by13.8%. (NPs). After titanium dioxide nanoparticles are deposited, the productivity of the nanoparticles
highly improves.

All isolates were shown to be concentration dependent on death, but in controller clusters of numerous samples of
tricks isolates showing impartial to diluents fillers, larval mortality ranged from 0.34 percent to 0.86 percent. Table 1

and RR99 (95 % CI). The average values ranged between 0.83 and 1.52, 0.97 and 2.66 for the amitraz RR5, RR90 and
RR99 correspondingly. The study demonstrates that among the fieldwork isolated strains, the controllable resistance
station is varied. Four field isolates (Al-Nasiriya, Al-Rifai , Al-Suq , al-Chibayish) demonstrated low resistance
levels based on RR90 and RR99 values, whereas the iso-late Ferozpur represents oversensitive to amitraz. The

deterioration schemes of tick larvae's death-rate in contradiction of amitraz dose log are displayed in Figure 1. In Al-
Nasiriya and Al-Rifai isolates, lower mortality slope values indicated heterogee Across the field isolates, there were
several populations with higher RR90 and RR99 values (Figure 2). The sensitive reference regression lines and the
five H. anatolicum field populations were found to have no parallelism or equality (p0.05).

The excessive humidity, ambient temperatures, and the care of sensitive intercrossbred animals in the area make it
difficult to improve milk production in this location all year (1-4).
Therefore, the frequent use of commercial brands for well-known insecticides with natural and chemical effects is
the most common approach in this field, which is the main entrance to re-arranging a successful strategy to combat
harmful insects, including ticks, of its extensive and indiscriminate use. This has led to increased resistance to those
pesticides and acaricides [12-19.] Despite all this, few cases of resistance to ticks have been recorded, as in the
genus H. anatolicum [7-10,35].
Investigation of the effect of acaricide was prepared as early detection of acaricide resistance in the tick parasite,
which was considered crucial in toxoid the subsequent selection of resistant ticks by using the same active species to
reduce the genetic detection that increases the acaricide resistance capacity and antioxidant secretions in pesticide
physiology, adult age test, age test of Larvae, larval pack test, and larval test are four biological tests that are carried
out in the laboratory to detect true acaricide resistance of ticks to pesticides where according to (Stone and Haydock
1962 ) test (LPT ) was the most common. Filter paper envelopes soaked in oil 100 larvae aged 1421 days were
injected with a laboratory quality acaricide and kept for 2448 hours to determine fatality. The test (LPT) was
adapted for early detection of the effect of insecticide resistance, especially amitraz, by replacing filter papers with
nylon sheaths as a basic substrate for the test [15]. The results of this study went with the conclusion reached by
Robertson and Preisler (1992) [36] that the heterogeneity of the recorded data along with the values of LC50 and
LC99 standards of the lethal concentration used, which is where the high results indicate the presence several of
individuals who carry the resistant allele. The current study results show that isolates of ticks with high relative risk
will become more homogeneous but will go towards more heterogeneity than before. Moreover, as a result of testing
in response to acaricide exposure, a heterozygous population will develop for the genes that are resistant to detection
and expression. Genetically, As the frequency of resistant genotypes increases, the gradient will decrease and the
line will shift to the right, indicating a positive correlation. So according to Robertson and Preisler (1992), It has
been found which line represents the representative line (see Figure 1). Amitraz resistance has been demonstrated in
many tick species using the (LPT) test. Many studies have been undertaken worldwide to determine the prevalence

of amitraz resistance in R. microplus. [6-12]. In a recent Ugandan research [19], R. decoloratus and R.
appendiculatus were amitraz resistant. Resistance to amitraz based on AIT has been found in R. microplus from
India. ([17-22]. The present experiments establish special pesticides for parasites such as multi-familial ticks and
hosts, whereas wanted amitraz using a concentration of the least expensive models in the test (LPT assay). and H.
anatolicum species were collected from the same ecological region and worked with other insecticides [11,35]

The anti-parasite activity of synthesized composite nanoparticles was tested against five different isolates of Ticks
(al-Nasiriya, al-Rifai, al-Suq, al-Chibayish, and Al-Shatra). Two methods were used in the experiment. The first
method was prepared using aqueous solutions, whose concentrations vary according to the different powers of the
laser. We use between 80 and 200 ml per joule. Then it was kneaded with nanoparticles with the effect of laser
pulses, or what is known as laser ablation. The best results came out of this experiment through nano-recruitment,
which showed the highest level and the best effect as an anti-tick for ticks and metabolic activity, as well as the
physiological impact on the different vital activities through exposure to varying concentrations of nanocomposites
that were attended by the first technique, which is aqueous solutions, which leads to the rapid penetration of body
tissues according to known physical laws such as diffusion and osmosis, as well as the effect of the osmotic pressure
of nano-solutions by increasing the concentration and overlapping of dissolved particles, as the images of techniques
that determine the dimensions of these compounds are clarified by evidence and documents. In addition to all of the
above, the effect of aqueous solutions and the amount of solute in them is added to the presence of oxidative stress
and the voltage generated by the energy gap of the electron, which is the basic principle on which the hypothesis of
catalyzing the inert titanium compound into an effective combination for the ability photodegradation the enzymes
and defense compounds of the parasites is based, which is a developed line of defense in these microorganisms. This
principle focuses on removing or reducing the electron orbit between the valence and the conductor bands. were

FIGURE 5. illustrates the efficacy of the nano Acaricide based on where the statistical analysis reveals the activity of the
nanocomposite.e
The above figure 5) shows the effectiveness of the Nano pesticide depending on where the statistical evaluation
shows that the activity of the nanocomposite showed an inhibitory activity for tick growth in a precise ratio between
the observer and the expected. The equation showed that the movement of the Nano acaricide increased at a fixed
rate (y = 3.53 + 1.56x*. In addition to the economic importance of the new compound being cheap, easy to use,
costly to prepare, and environmentally friendly. CONCLUSION
Researchers have created, characterized, and tested titanium oxide nanoparticles for application in tick control in
domestic animals (a new type of acaricide). Pulsed Nd: YAG laser ablation was used as an unique approach to
accomplish this. Another way to this problem is: Pulsed YAG laser ablation of titanium dioxide nanoparticles was
employed in this experiment. The antioxidant system was photodegraded and the oxidative responses were estimated
using these nanoparticles. A novel species photocatalytic visible-light activity of co-doped TiO2 with a wide range
of pulses was investigated. Atomic force microscopes were used to examine the deposit materials' surface
morphology (AFM). Using AFM, it was found that the TiO2NPs in water had an average grain size of 150 nm and
an RMS roughness value of 2.27 nm. The AFM was used for both of these measurements. Before and after titanium
dioxide nanoparticles (NPs) were applied to the solar photovoltaic characteristics, the bioassay of tick mortality rates
and time against five separate isolates of ticks indicated unique associations. as a result of This article sheds insight
on some of the factors that may have contributed to the rise of the resistance. To investigate the anti-parasitic
properties of manufactured nanoparticles, Finney used five different tick strains. Log-probit linear regression was
used to test the validity of the assessment (1971). TiO2 as an acaricide was studied using the equation y = 3.53 +
1.56x*, which showed that the growth of the Nano acaricide was constant. Besides being affordable, user-friendly,
environmentally benign, and costly to produce, the new material has economic importance.

Road accidents are a major problem these days. A few of them are due to the human errors while controlling the traffic signals. In this era of advanced technologies, there are many ways to prevent these kinds of blunders. This paper describes an automatic traffic signal which works on piezoelectric power. The traffic lights are working only when the traffic is passing. This way, accidents are not only minimized, but also power conservation can be done. Specially, during midnight or dawn when the traffic is less. This supply of power of the system is self-dependent and is independent of weather or power failure. In an addition, this supply of power can also be used to provide electricity to the street lights and the CCTV Cameras. This way, it can be used to conserve a huge amount of electricity.

A survey was conducted from January 2015 to December 2015 in 12 provinces in Iraq to identify and classify the seasonal distributions of the major hard ticks species (Ixodidae) found on cattle in the north, middle and south of Iraq. A total of 17,156 adult hard ticks were collected from 3,812 indigenous cattle. Sampling was repeated from the same provinces every month to determine the seasonal diversity. Five species belonging to two genera (Hyalomma and Rhipicephalus) were identified; the most abundant ticks were Hyalomma anatolicum 41.72%, Rhipicephalus turanicus 24.60%, Hyalomma turanicum 16.65%, Hyalomma scupense 13.26% and Rhipicephalus annulatus 3.67%. There were differences between each province related to the environment as well with the previous studies.

Detection of resistance levels against amitraz and malathion in Rhipicephalus (Boophilus) microplus collected from four districts of Jammu region (India) was carried out using the adult immersion test. The regression graphs of probit mortality of ticks plotted against log values of concentration of drugs were utilised for the determination of slope of mortality, lethal concentration for 50% (LC50), 95% (LC95) and resistance factor (RF). On the basis of the data generated on variables (mortality, egg mass weight, reproductive index and percentage inhibition of oviposition) the resistance level was categorised as I, II, III and IV. Out of these four districts, resistance to amitraz was detected at level I in Udhampur (RF = 2.81), Jammu (RF = 2.53) and Samba isolates (RF = 2.24) whereas Rajouri isolate was found susceptible (RF = 1.0). Resistance to malathion was detected at level I in Udhampur (RF = 4.01) and Jammu isolates (RF = 1.76) whereas Rajouri (RF = 0.472) and Samba (RF = 0.199) isolates were found susceptible. The data generated on amitraz and malathion resistance status will help in formulating a tick control strategy in the region.

Background: Acaricide failure has been on the rise in the western and central cattle corridor of Uganda. In this study, we identified the tick species associated with acaricide failure and determined their susceptibility to various acaricide molecules used for tick control in Uganda. Methods: In this cross sectional study, tick samples were collected and identified to species level from 54 purposively selected farms (from 17 districts) that mostly had a history of acaricide failure. Larval packet test was used to screen 31 tick populations from 30 farms for susceptibility at discriminating dose (DD) and 2 × DD of five panels of commercial acaricide molecules belonging to the following classes; amidine, synthetic pyrethroid (SP), organophosphate (OP) and OP-SP co-formulations (COF). Resistance was assessed based on World Health Organization criteria for screening insecticide resistance. Results: Of the 1357 ticks identified, Rhipicephalus (Rhipicephalus) appendiculatus and Rhipicephalus (Boophilus) decoloratus were the major (95.6%) tick species in farms sampled. Resistance against SP was detected in 90.0% (27/30) of the tick populations tested. Worryingly, 60.0% (18/30) and 63.0% (19/30) of the above ticks were super resistant (0% mortality) against 2 × DD cypermethrin and deltamethrin, respectively. Resistance was also detected against COF (43.3%), OP chlorfenvinphos (13.3%) and amitraz (12.9%). In two years, 74.1% (20/27) of the farms had used two to three acaricide molecules, and 55.6% (15/27) rotated the molecules wrongly. Multi-acaricide resistance (at least 2 molecules) was detected in 55.2% (16/29) of the resistant Rhipicephalus ticks and significantly associated with R. decoloratus (p = 0.0133), use of both SP and COF in the last 2 years (p < 0.001) and Kiruhura district (p = 0.0339). Despite emergence of amitraz resistance in the greater Bushenyi area, it was the most efficacious molecule against SP and COF resistant ticks. Conclusion: This study is the first to report emergence of super SP resistant and multi-acaricide resistant Rhipicephalus ticks in Uganda. Amitraz was the best acaricide against SP and COF resistant ticks. However, in the absence of technical interventions, farmer-led solutions aimed at troubleshooting for efficacy of multitude of acaricides at their disposal are expected to potentially cause negative collateral effects on future chemical tick control options, animal welfare and public health.

Ticks and tick-borne diseases are a major constraint for the sustainable cattle industry in tropical and subtropical regions of the world. Application of chemical acaricides is the most used tick control strategy but has led to development of resistant tick populations. The aim of the present study was to determine the amitraz resistance status of Hyalomma anatolicum ticks from various districts of Punjab, India by modified larval packet test (LPT) using nylon membranes as substrate and formulated amitraz (Taktic® 12.5% EC, MSD Animal Health, India). The regression graphs of probit mortality of larval ticks plotted against log values of increasing concentrations of amitraz were utilized for the determination of slope of mortality, lethal concentration for 50% (LC50), 90% (LC90) and 99% (LC99) with 95% confidence interval (CI), and resistance ratios (RR50, RR90 and RR99). The mean values of RR50, RR90, and RR99 ranged from 0.83 to 1.52, 0.97 to 2.66, and 1.10 to 4.19, respectively, indicating variable resistance status among the field isolates. On the basis of RR90 and RR99 values, four field isolates (Faridkot, Ludhiana, Patiala and Sangrur) showed low levels of resistance, whereas the Ferozpur isolate was susceptible to amitraz. The data generated on amitraz resistance status in H. anatolicum from Punjab, India can be used as an indicator for the management of the species in the state.

Imagine a statistics book for bioassays written by a statistician. Next, imagine a statistics book for bioassays written for a layman. Bioassays with Arthropods, Third Edition offers the best of both worlds by translating the terse, precise language of the statistician into language used by the laboratory scientist. The book explains the statistical basis and analysis for each kind of quantal response bioassay in just the right amount of detail. The first two editions were a great reference for designing, conducting, and interpreting bioassays: this completely revised and updated third edition will also train the laboratory scientist to be an expert in estimation of dose response curves. New in the Third Edition: • Introduces four new Windows and Apple-based computer programs (PoloJR, OptiDose, PoloMixture and PoloMulti) for the analyses of binary and multiple response analyses, respectively • Replaces out-of-date GLIM examples with R program samples • Includes a new chapter, Population Toxicology, and takes a systems approach to bioassays • Expands the coverage of invasive species and quarantine statistics Building on the foundation set by the much-cited first two editions, the authors clearly delineate applications and ideas that are exceptionally challenging for those not already familiar with their use. They lead you through the methods with such ease and organization, that you suddenly find yourself readily able to apply concepts that you never thought you would understand.

Acaricide resistance is a major obstacle to the control of Rhipicephalus microplus. Historically, the indiscriminate use of chemical compounds has contributed to the selection of populations resistant to different classes of acaricides. Therefore, multiple acaricide resistance is an important threat to the chemical control of the cattle tick. To investigate the occurrence and extent of multiple resistance to acaricides in Southern Brazil we performed larval tests with cypermethrin, chlorpyriphos, amitraz, fipronil and ivermectin on 104 cattle tick field samples from different ranches in Rio Grande do Sul, between the years 2013 and 2015. Adult immersion tests with a commercial formulation mixture of chlorpyriphos and cypermethrin were performed on 75 samples. Four levels of resistance were established according to the mortality of larvae: Level I: mortality between 82% and 95%; Level II: mortality between 57% and 82%; Level III: mortality between 25% and 57%; and Level IV: mortality lower than 25%. Resistance to cypermethrin was detected in 98.08% of the samples evaluated, mostly at resistance level IV. The frequency of samples resistant to amitraz, chlorpyriphos, ivermectin and fipronil was 76.92%, 60.58%, 60.58% and 53.85% respectively. Multiple resistance to three or more compounds was found in 78.85% of the samples. The results obtained in this study are alarming and reveal a new scenario for the challenge of tick control using chemicals. This is an issue of high importance to cattle production systems where this tick is responsible for a high economic impact.
