Background:
Fumigants like phosphine, methyl bromide and sulfuryl fluoride are highly effective for the control of structural, storage and agricultural arthropod pests. Unfortunately, many of these synthetic compounds are highly toxic to people, many pests have developed resistance to these compounds, and methyl bromide, the "gold standard" for fu...
Glucose-aversion is a heritable trait that evolved in a number of German cockroach (Blattella germanica L.) populations in response to strong selection with glucose-containing insecticide baits. However, in the absence of glucose-containing bait, glucose-averse (GA) cockroaches have lower performance than wild-type (WT) cockroaches in several fitne...

Cockroaches are pests of veterinary and public health importance with their role as pathogen spreaders.
The aim of the present study was to determine the distribution of synanthropic species of cockroaches
in animal farms (AFs) and food processing plants (FPPs). The survey was carried out in 52 sites (42
AFs and 10 FPPs), by questionnaire-visual survey and monitoring catch method. The presence of
cockroaches was found in 78.57% of AFs and 0% of FPPs. The industrial pig farms are the most
frequently and highly affected – all of them were infested in high density. The oriental cockroach (Blatta
orientalis L.) was the dominant species. An inhomogeneous distribution was found in invased pig farms
with preferred areas of localization in the new-born sectors and sanitary filters. The obtained results are
proof of the need to strengthen insect monitoring and pest control in animal farming, especially in pig farms.
... The samples were brought to the Entomology Laboratory of Sylhet Agricultural University and preserved in 70% (v/v) ethanol for further identification and grouping into functional groups (predator, parasitoid, and pests). The preserved samples were placed in Petri dishes and identified to the family level using a microscope, colored photographs in books and published papers for the families Araneae (Levi 2002;Coddington 2005;Hamasaki et al. 2008;Nentwig et al. 2018), Blattodea (Baur et al. 2004;Hristov and Chobanov 2016), Coleoptera (Kurosawa et al. 1998;Lawrence et al. 1999;Choate 2003), Dermaptera (Kočárek 2014;Miles 2015), Diptera (Buck et al. 2009;Sawaby et al. 2018), Hemiptera (Weirauch et al. 2014), Hymenoptera (Shaw and Huddleston 1991;Goulet and Huber 1993), Isoptera (Scheffrahn et al. 2003(Scheffrahn et al. , 2006, Lepidoptera (Dombroskie 2011;Smetacek 2015;Parveen and Khan 2017;Kunte et al. 2020;Sondhi et al. 2020), Mantodea (Rivera 2010), Odonata (Bouchard 2004;Wright and Peterson 1994) and Orthoptera (Smith et al. 2004). Besides, taxonomic features of textbooks were also used for identification (Schell and Latchininsky 2007;Chapman 2013;Zettler et al. 2016). ...
Naturally or artificially created diverse vegetation habitats often promote natural enemies of crop pests. The abundance of natural enemies increases with response to increasing habitat complexity at various spatial scales. Against this backdrop, we assessed the contribution of shade trees to conserve beneficial predatory and parasitoid arthropods at local scale in a subtropical tea agroecosystem in Bangladesh. Arthropods viz., predators and parasitoids were captured using Malaise traps in plots with shade trees and in those without shade trees having three different densities of tea bushes due to naturally created gaps (large-gap, small-gap and control). The number of arthropods captured in each plot corresponded to shade-tree and tea-bush densities, such that arthropod abundance in the shade-tree plot was twice that of the control plot, which had similar tea-bush density but no shade trees. Predators were least abundant in the large-gap plot, which had the lowest tea-bush density and no shade-trees, while 2.4–3.8 folds predators were captured in the control and shade-tree plots. There was a negative correlation between mean light intensity and number of predators in the four plots. Similar trends were observed for parasitoids. Relative abundance of predatory Staphylinidae was more than twice in the shade-tree and small-gap plots compared to control and large-gap plots. Relative abundance of parasitoid Ichneumonidae was ranked as small-gap > shade-tree > control > large-gap plots. Our results suggested that shade trees may help conserve and promote beneficial arthropods such as predators and parasitoids in tea agroecosystems.

... In Europe, this family is represented by a small number of taxa, distributed exclusively in the Mediterranean area (Bohn 2022). Although still restricted to the Mediterranean region, the most widespread and well-known corydiid species is Polyphaga aegyptiaca (Linnaeus, 1758) which inhabits some countries neighboring Serbia (Hristov and Chobanov 2016;Bohn 2022). This species, also named the Egyptian desert cockroach, is the only representative of its genus in Europe (Bohn 2022). ...
Polyphaga plancyi Bolívar, 1883, also known as Chinese sand roach, it is a large Corydiidae species with a native distribution that includes several Chinese provinces and southern part of the Russian Far East. It is a well-known insect in traditional Chinese medicine, and the biological activity of the compounds isolated from it are actively studied. So far, there are no records of this species outside its natural range, at least outside China. In this article, we present the first record of P. cf. plancyi specimen collected in Europe, probably imported from Shanghai. The specimen was recognized as a non-native cockroach species to Europe via photo posted on social media, and it was subsequently taxonomically identified. Details of its possible origin, its morphology, importance of citizen science, as well as annotations on the other synanthropic cockroaches in Serbia are provided.

The amber cockroach (Ectobius vittiventris) is a Mediterranean species that was originally widespread in southern Europe (from southern Spain and France through Switzerland, Italy, Slovenia, Croatia, Bulgaria) and in the NW of West Asia (Turkey, Georgia, Azerbaijan and SW Russia in Krasnodar region). At the end of the twentieth century, the species began to appear in greater numbers in the northern states of Europe (Germany, Austria, Slovakia, Hungary, Czech Republic and Great Britain). In Slovakia, E. vittiventris was registered in 2012 in Bratislava and since then it has spread mainly in its vicinity. We recorded a detailed course of ootheca formation. Part of the eggs hatch in the autumn in the year of laying and some overwinter and hatch just in the spring or later in the summer of the following year. Nymphal development has seven instars and lasts more than one year. Males lived in the rearings for an average of 25 days, females 70 days (maximum 190 days).

The species of Musca domestica Linnaeus, 1758 was most abundant compared with other insects, whereas the species of Tenebrio obscurus Fabricius, 1792 was the least population in the present study.
This study was performed to investigate the phylogenetic characters of the cockroaches in XXX region for mitochondrial cytochrome c oxidase subunit I (mt-COI), mt-COII, and internal transcribed spacer-2 (ITS-2) gene regions, and to determine their mechanical transmission of medically important parasites. PCR-restriction fragment length polymorphism (RFLP) was performed using mt-COI, mt-COII, and ITS-2 DNA gene regions to identify cockroach species (n=220) collected from different regions. Differentiation of cockroach species was based on RFLP models using two restriction enzymes: AvaI and EciI. For phylogenetic analysis, mt-COI, mt-COII, and ITS-2 DNA barcode regions were amplified with standard primers. The amplicons obtained were purified and sequenced with PCR primers. According to PCR-RFLP, cockroach species were identified as Blattella germanica (n =105), Blatta orientalis (n = 86), and Periplaneta americana (n = 29). A total of 13 haplotypes were detected and Maximum likelihood (ML) analyses revealed that the sequences of all three species for the three gene regions showed monophyletic structuring. The cockroaches were examined for the presence of parasites. It was determined that of the 58 parasitic forms identified belonged to helminth species 46 (79.3%) and protozoan species and 12 (20.7%). The results showed that B. germanica (58.6%) had the highest prevalence, followed by Bl. orientalis (32.8%) and P. americana (8.6%). The study findings not only contribute to the molecular epidemiology of cockroaches but also confirm that they play an important role as mechanical vectors of protozoan and helminth parasites.
Necrophilous insects, mainly those belonging to the orders Diptera and Coleoptera, are attracted to specific stages of the decomposition of a dead organism, following a pattern of chronological succession. Their classification and identification, together with the precise determination of their life cycle and age, are two determining factors in approaching the postmortem interval, the time interval that has occurred between death and the discovery of a dead body. The vesting of the knowledge of the biodiversity of necrophilous species of a particular area can become an important tool in the hands of a forensic entomologist providing additional information in forensic investigations. The current study, aims to provide the first data on the composition of the fauna of the necrophilous species of the urban ecosystem of Athens, Greece.For this purpose, an experimental study was carried out in three different locations of the main campus of the Agricultural University of Athens, in the context of which 3 different types of decomposed material of animal origin (beef liver, chicken stomach and fish) were exposed under natural conditions in two improvised types of traps (bottle and pitfall traps) aiming to capture forensically important insects of the area. During the sampling period, a total of 105 different arthropod species were recorded from 12 orders, of which 41 species are considered necrophilous. Furthermore, the population fluctuation of the most abundant necrophilous species was studied and their correlation with the environmental factors of temperature and humidity was analyzed and discussed. In addition, various ecological parameters of the most abundant species found in the context of this study were determined, whereas the reasons why only specific taxa were found to be dominant were then discussed, as well as the effect of the urban environment of Athens as an impact factor on the biodiversity of necrophilous species was also examined. In addition, the behavior of necrophilous Diptera, Coleoptera and all necrophilous insects captured towards the use of the three different animal baits was studied, while the possibility of the presence of a trophic preference towards a specific type of bait was also examined. Finally, a discussion is held on the role of the scientific branch of Forensic Entomology in Greece, with the aim the results of this preliminary study to constitute the first step for further research, purposing in the application of this science in future forensic investigations, which will be carried out in Greece.
