Techapp.pdf), E. vittiventris cockroaches are considered to be harmless and have not been associated with human disease or transmission of pathogens. We did not observe any allergic reactions or an increase in colonization or infection rates of multidrugresistant organisms. B. germanica cockroaches are nocturnal, cannot fl y, are always encountered within human habitations, and require speciali...

German cockroach, Blattella germanica (L.) (Dictyoptera: Blattellidae), catch by five types of traps and modifications of each, were tested under controlled laboratory conditions. Cockroach catch differed significantly among traps. Lo-line trap caught the greatest number of cockroaches in the test arena for each size class (23% small nymphs, 39% of gravid females, and 60% of other size classes ...

We undertook a study of the mechanical transmission of parasitic organisms in cockroaches in the Samutprakarn province of Thailand. In this study, 920 cockroaches were obtained from 18 open-air shopping markets in 5 districts and 1 subdistrict of this province. All cockroaches were captured during their feeding time in their natural habitat. Direct wet smear and modified acid-fast bacilli stain...

Background. Cockroaches are source of bacterial infections and this study was aimed to assess bacterial isolates and their antimicrobial profiles from cockroaches in Gondar town, Ethiopia. Methods. A total of 60 cockroaches were collected from March 1 to May 30, 2014, in Gondar town. Bacterial species were isolated from external and internal parts of cockroaches. Disk diffusion method was used ...

Cryptocercus punctulatus and Parasphaeria boleiriana are two distantly related xylophagous and subsocial cockroaches. Cryptocercus is related to termites. Xylophagous cockroaches and termites are excellent model organisms for studying the symbiotic relationship between the insect and their microbiota. In this study, high-throughput 454 pyrosequencing of 16S rRNA was used to investigate the dive...

BACKGROUND & OBJECTIVES Cockroaches (Diploptera punctata) are basically tropical insects and will do their best to find a home that is both warm and moist. Their involvement in the transmission of tropical diseases is poorly investigated in Africa. METHODS A study on the bacterial, fungal and parasitic profile of cockroaches trapped in and around houses in Ekpoma was carried out using standar...

Here, I review the article "Changes in taste neurons support an adaptive behavior in cockroaches" by Wada-Katsumata et al. (2013). Their article elucidates the mechanism by which some cockroaches avoid eating poisoned bait: a change in the response properties of cells that transduce the tastant glucose and related sugars. Specifically, the data show that in cockroaches that avoid glucose consum...

Foraging cockroaches ingest insecticide baits, translocate them, and can cause mortality in untreated cockroaches that contact the foragers or ingest their excretions. Translocation of eight ingested baits by adult male Blattella germanica (L.) was examined in relation to the type of the active ingredient, formulation, and foraging area. Ingested boric acid, chlorpyrifos, fipronil, and hydramet...

German cockroaches are common pests of confined swine production in North Carolina and other southeastern states. Vector competence of German cockroaches for one of the most important porcine bacterial pathogens, verotoxigenic Escherichia coli F18, was evaluated in laboratory bioassays using a culturing approach followed by multiplex PCR. In addition, the populations of fecal coliforms from the...
