Tetranychus urticae Koch Acari: Tetranychidae ’nin Değişik Populasyonlarının İki Selektif Akarisite Karşı Duyarlılıkları ve Duyarlılık Mekanizmaları Üzerinde Araştırmalar

Adana, Antalya, İzmir ve Urfa’dan pamuk üzerinden toplanan 9 farklı Tetranychus urticae Koch populasyonunun iki selektif akarisite dicofol ve bromopropylate karşı duyarlılığı biyoassay ve biyokimyasal yöntemlerle incelenmiştir. Rezidü biyoassay petri kabı-ilaçlama kulesi ile dicofol ve bromopropylate uygulanarak tüm populasyonlarda LC50 veLC90 değerleri belirlenmiştir. Standart hassas GSS populasyon ile karşılaştırılarak bulunan direnç oranlarının dağılımı dicofol ve bromopropylate için sırasıyla 1.112-2.497 ve

Investigations on Resistance and Resistance Mechanisms of Different Populations of Tetranychus urticae Koch Acari: Tetranychidae Against two Selective Acaricide

Nine different populations of Tetranychus urticae Koch were collected on cotton from Adana, Antalya, İzmir and Urfa. Their response against two selective acaricide dicofol ve bromopropylate was investigated using both conventional bioassay and biochemical assays. LC50 and LC90 values of dicofol and bromopropylate were determined for all populations using residual bioassay petri dish-spray tower . Resistance ratios were determined by comparing the samples with standard susceptible strain, GSS, and for dicofol and bromopropylate were found to be 1.112-2.497 and
