Kajian Status Resistensi Tungau Hama Brevipapalpus phoenicis dan Tungau Predator Ambleyseius deleoni sebagai Dasar Evaluasi Aplikasi Pestisida

Edit
Abstrak: The Increasing demand of tea product this decade causes the tea become prospective commodity. In other hand, free residual of pesticide in the tea culture could inhibit the rise of this demand. Therefore the evaluation of pesticide application policy in the field should be conducted, especially in term of the effect of the residual of pesticide on the resistance status of the mite. The research had been done using survey and experimental methods. The aim of the research was to decide the resistance status of the pest mite of tea leaf Brevipalpus phoenicis and it main predatory mite Ambleyseius deleoni on the application of three kind of pesticides (herbicide, fungicide and acaricide), and its effect on predator-prey feeding link. The result shows that both B. Phoenicis and A. deleoni are still resistant to herbicide (Round Up 486 AS) and fungicide (Kocide 77WP), but they are susceptible on acaricide (Kelthane 200EC). Also pesticide application has no effect significantly on predator-prey link (predation level). The conclusion is pest mite B. phoenicis is resistant on fungicide (Kocide 77WP) and Herbicide (Round Up 486 AS) but it is not resistance on Acaricide (Kelthane 200EC). Application of pesticides has no effect significantly on predator-prey link (predation level), so predatory mite A. deleoni is still effective in biological control for its prey.
