Study of the direct action ofpreparations of the synthetic pyrethroid group in the processing of red chicken mite

In the domestic market, the range of insec-toacaricides used for processing poultry and industrial premises is quite wide. But due to improper and prolonged use of drugs with the same active substance, mites have resistance. The purpose of our research was to study the direct action of insectoacaricides from the group of synthetic pyrethroids on the model “Red Chicken Mite”. In the presented work, the direct effect was studied - the action of the drug, which causes the death of larvae, nymphs, and adults of the red chicken mite in direct contact with the active substance. To conduct 2 series of studies, red chicken mites in an approximate amount of 200 individuals per petri dish were placed on the bottom of the Petri dishes. The edges of the cup were treated with a neutral cream. Then applied the studied drugs in concentrations of 0.005%; 0.01%; 0.05%; 0.1%; 0.5% by the method of small drop spraying. The control in the experiments was untreated Petri dishes with red chicken mites. In the first 3 hours, constant monitoring of the viability of Dermanyssus gallinae was carried out. Then the changes were recorded every 6 hours. On the second day after the experiment, the changes were recorded 1 time per day. All petri dishes were kept at room temperature 18-20 оС. As a result of studies aimed at studying the direct acaricidal effect of drugs from the group of synthetic pyrethroids, we can conclude that, in a two-time test, the most effective solutions were 0.5% concentration of solutions of drugs: esbiotrin, tetramethrin, cyfluthrin, permethrin, deltamethrin, with the exception of esfenvalerate
