In vitro effectiveness of selected acaricides against red poultry mites (Dermanyssus gallinae, De Geer, 1778) isolated from laying hen battery cage farms localised in different regions of Poland.

摘要

Investigation was carried out on red poultry mites Dermanyssus gallinae collected from 32 battery cage farms of laying hens localised in 14 voivodships. The following insecticides were used: Alfasekt ( alpha -cypermetrin), Blaxime (phoxim), ByeMite (phoxim), Ficam (bendiokarb), Galtox B (fenitrotion, dichlorphos, alpha -cypermetrin), Knox-out (diazinon - microcapsule form), Master (chlorpyrifos - microcapsule form), Skorpion (sevin, alpha -cypermetrin), Sumition (fenitrotion - microcapsule form). The efficacy of the acaricides was investigated on the plates using the veneer disc as the ground. The insecticides were used in concentrations and volumes recommended by producers of preparations. Efficacy study showed that the most effective against most of red mite populations were phoxim Blaxime and Bye Mite (89%-100% in 13 voivodships) and one carbamate preparation - Ficam (92%-100% in 11 voivodships). Relatively effective turned out to be also another carbamate acaricide with alpha -cypermetrin supplement - Skorpion. Phosphoroorganics in microcapsule form and acaricides containing only alpha -cypermetrin demonstrated low effectiveness.
