Parasitic mites such as Acarapis woodi and Varroa destructor mite are examples of such threats that can cause a great deal of damage to honey bee populations. The present study was aimed to evaluate the infestation level and prevalence of apiaries and bees colonies with Acarapis woodi and Varroa destructor in Kurdistan province. A total of 100 apia...

Abstract
Varroa spp. is an important ectoparasite in the honey bee that is distributed
worldwide and it may cause to decrease in the population in the honey bee colonies.
This study was conducted to determine the frequency of seasonal distribution of Varroa
mite in apiaries of Kerman province from 2017-to 2018. 1500 hives were sampled
randomly in different apiaries in the Kerman province. Detection of Varroa spp.
infestation in adults honey bees was conducted by Ether wash. The prevalence of
Varroa spp infestation in apiaries was 32.9%. The highest frequency of infection in
winter was determined as 46.6% and the lowest infection rate was found in spring
(24%). The highest and lowest mean density rate of infestation were 33% and 17%.
Regarding the rate of prevalence of Varroa spp in the apiaries of Kerman province, it
needs to have a regular control program in order to decrease the rate of infestation in
this region.

... In this investigation, presence of the tracheal mite Acarapis was not found in the HPMN, for which the results match to those found in HHP in other tropical zones (Mart ınez-Ces areo et al., 2016;Mart ınez Puc et al., 2011) and are superior in HHP in other regions with mild humid climates (1.8%) (Calder on & S anchez, 2011). In warm and tempered climates in the middle east with 13.0%, 5.5% and 4.4%, 1.0% (Khezri & Moharami, 2017;Rahimi, Mahdavi, & Asadi, 2013;Shakib & Mehdi, 2016). It is possible that in regions with a tropical climate, Acarapis will not be able to develop efficiently, possibly because of the minimal variation in temperature between different seasons. ...
The presence of pathogens in fecundation hives represents a source of infection for queen bees. The objective of this investigation was to determine the prevalence of Varroa, Nosema, and Acarapis in hives for the production of mating nuclei (HPMN). 239 samples of adult bees of 17 apiaries of a queen bee breeding system were analyzed during the winter and summer of 2016. The prevalence of Varroa and Nosema was higher in winter (79.1% and 55.4%, respectively) than in summer (65.9% and 33.0%, respectively). However, Acarapis was not found. Varroa infestation was 2.55 ± 0.82 mites/100 bees, and Nosema 145 ± 24 × 10³ spores/bee (Standard deviation of the mean). The probability of finding Nosema, in the presence of Varroa, was 3.8 and 1.1 times higher in winter than in summer, respectively. We, therefore, conclude that HPMN has a higher incidence of varroasis and nosemosis during winter and nosemosis increases in the presence of varroasis. We, on the other hand, consider acariosis, absent in the region of study.
... Casanova and Perruolo (1992) reported a prevalence of Acarapis woodi amounting to 2.7% in apiaries in Tachira State (Venezuela). In Kurdistan region, prevalence of Acarapis woodi infestation was 1% in apiaries and 0.26% in hives (Khezri et al., 2017). In the apiaries of the Japanese honey bee Apis cerana japonica, infestations of Acarapis woodi have spread rapidly over the mainland of Japan, causing damage and collapse of colonies (Sakamato et al., 2017). ...
This study was aimed to investigate the prevalence of acariosis in honeybee colonies of Apis mellifera intermissa in Algeria. To this end, samples of bee colonies of the Apis mellifera intermissa race were taken from the brood frames for assessment of acariosis induced by Acarapis woodi in five provinces in Algeria viz., Tizi Ouzou, Blida, Boumerdès, Algiers, and Bouira. A sample of 100 to 150 bees spread over three to five colonies for each apiary was observed. Presence of this parasite was examined using laboratory and microscopic methods that entailed dissecting the thoraxes of the bees to expose their tracheas. Each trachea was examined under a microscope. In the case of the infected bees, the mites appear as small oval bodies attached to the transparent walls of the tracheas. According to the examination and analysis results, two cases of acariosis
were observed in two colonies in the same apiary in the province of Boumerdès. In Bouira province, only one colony infested by the mite was found. Meantime, no single case of acariosis was detected in the provinces of Blida, Algiers, and Tizi Ouzou. These results indicate low prevalence of this disease in Algeria. For the infected apiaries, there is so far no 100% effective treatment for acariosis. Once this disease is present in the apiary,
the beekeeper must control its development at a level that will not affect the health of the colony.

Honey bee ectoparasites infestations may affect the insect and cause the population reduction and economic damage
in apiculture system. The present study was aimed to determine the Prevalence of Varroa and association of Colony
Collapse Disorder (CCD) in apiaries in Urmia suburb, Iran, over one year (2017- 2018). A total of 840 beehives of 120
apiaries in Urmia suburb were randomly sampled. Of those, 301 bees (35.83%) and 190 bee larvae (18.33%) were infested
with Varroa. The highest infestation was found in bees and bee larvae in summer. 93 out of 840 apiaries had CCD
signs. 61 out of 93 apiaries (65.59%) with CCD were infested to Varroa. There was a significant relation between CCD
and Varroa (p <0/05). From the results of this work, it was concluded that Varroa mites are a prevalent ectoparasite in
apiaries of Urmia suburb which may have an important role in the incidence of CCD.
