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