Acaricide-inducible differential gene expression was studied in larvae of Rhipicephalus (Boophilus) microplus using a microarray-based approach. The acaricides used were: coumaphos, permethrin, ivermectin, and amitraz. The microarrays contained over 13 000 probes, having been derived from a previously described R. microplus gene index (BmiGI Version 2; Wang et al., 2007). Relative quantitative ...

A strain of Boophilus decoloratus, resistant to fenvalerate, was subjected to larval immersion, adult immersion and stall tests using the following classes of ixodicides: organochlorines, organophosphates, a diamidide and pyrethroids. A susceptible reference strain of B. decoloratus was used for comparative purposes. The results indicated a high level of resistance to DDT and camphechlor, sligh...

The effect of agrochemicals and beekeeping treatments on drones have not been widely investigated compared to workers or queens. In the present study, we chronic exposure chemicals set (deltamethrin, acetamiprid, oxalic acid, fumagillin, amitraz) some sperm parameters histomorphology seminal vesicles. We also assessed colony development nosema load before after exposure. Thirty native Apis mell...

Abstract The aim of the study was to analyse intestinal microbiota honey bees ( Apis mellifera ) treated with amitraz. In present study, microbiological profile bee intestines showed minor changes in following application A comparison numbers bacteria and fungi revealed a positive downward trend number fungi. decreased bacteria, included E. coli especially Clostridium spp., which were not isola...
