Özet

The predacious mite Amblyseius swirskii AthiasHenriot (Acari: Phytoseiidae) is an effective biocontrol agent of whiteflies, thrips and spider mites. A native Turkish population of the predator were artificially selected by an acaricide formulation that is a mixture of bifenazate and abamectin. Compared with its native population, selections in the laboratory for 6 consecutive generations resulted in 25 folds bifenazate and abamectin resistance. To examine the relative fitness of the abamecin and bifenazate-resistant population of A. swirskii, the life table parameters of resistant and susceptible populations of A. swirskii feed on eggs of Tetranychus urticae (Koch) (Acari: Tetranychidae) were observed under controlled conditions (27±1°C, 80±5% RH, L:D, 16:8).
