Insectoacaricide activity of 5% D-cyphenothrin Emulsion against argasid ticks and biting lice

Abstract

The purpose of the research is to evaluate the insectoacaricidal activity of the drug 5% D-cyphenothrin Emulsion against argasid ticks and biting lice in different concentrations.Materials and methods. We carried out a parasitological examination of an open-type cinderblock poultry building in peasant household BUGLEN-2 (the Republic of Dagestan) using the avian ectoparasite collecting methods of B. A. Frolov (1975). The studies were performed using procedures outlined in the studies by A. A. Nepoklonov and G. A. Talanov (1973), M. V. Arisov and I. A. Arkhipov (2018) as modified. In the Laboratory of Ectoparasitosis in the VNIIP – FSC VIEV, the acaricidal activity of 5% D-cyphenothrin Emulsion was evaluated against argasid ticks and LD50 and LD95 were determined. The insecticidal activity of the studied drug in different concentrations against the biting lice Menopon gallinae and Menacanthus stramineus was studied on naturally infected chickens that were kept on the farm. Parasitic arthropods were identified to species using identification guides by I. G. Galuzo (1957), N. A. Fillipova (1966) and D. I. Blagoveshchensky (1940).Results and discussion. In laboratory, we observed rapid death of argasid ticks within 30 minutes after their contact with absorbent paper impregnated with 0.005% and 0.05% concentrations of the studied drug. In the assessment of the 5% D-cyphenothrin Emulsion insecticidal activity against biting lice of two species Menopon gallinae and Menacanthus stramineus on naturally infected chickens, we observed the death of parasitic insects after 24 hours on the birds treated with a 0.005% emulsion. Thus, the minimum effective concentration of 0.005 % of the study drug, 5% D-cyphenothrin Emulsion, was determined for the above parasitic arthropods.
