PERLUNY A EVALUASI KINERJA PARASITOID PADA HAMA DAUN KELAPA : BRONTISPA LONGISSIMA GESTRO (COLEOPTERA: CHRYSOMELIDAE) DI KABUPATEN ENDE-FLORES

Abstract

Brontispa longissima Gestro (Coleoptera: Chrysomelidae) is ones of the most important pest who attack of many family palms in South East Asia.  In Indonesia, Brontispa longissima has. becomes a primer pest on coconut. It was Decreasing yield result up to  30 - 40  % returns and  5% of the attacked crops will die. Ones of the failed reason of control action is a low preventive system on every territory entrance, otherwise, coconut was a needful and fast-moving commodity for people and industry. The second reason is secondary commodity assumes and low cropping system caused pest and disease uncontrolled. Three bio-control usages on-field need to monitored caused farmers incapable. The success indicator for parasitoid release was quick and easy to adapt for the parasitoid. It was related " three-generation three years," theory by Ev Clausen,  the expert of integrated pest and management control from California says: a)  The perfectly of Effective parasitoid/predator always quick and easy to adapt,  b)  The failed parasitoid/predator to adapt easily and quickly was an ineffective  indicator for bio-control, c) Parasitoid release or exotic predator could be stopped for  3  years if no evidence adapt on fields. According to the experts, the key for the success of system controlling above depends on cropping agroecosystem stability.
