摘要

Conopomorpha cramerella (Snellen) (Lepidoptera: Gracillariidae), known as the cocoa pod borer (CPB), is the main pest on cocoa plantation mainly in the Central Sulawesi Province-Indonesia. This pest significantly reduces cocoa production and the farmers' income. Entomopathogenic fungi such as Verticillium lecanii (Zimm) Viegas have potential that used as a biological control agent. Pathogenicity of V. lecanii Central Sulawesi strain against CPB has been studied under in-vitro conditions. This strain was isolated from the prepupae stadium of CPB. Testing of four V. lecanii conidia density (10~4, 10~6, 10~8, 10~(10) ml~(-1)) showed a significant effect on the mortality of prepupae, pupae and imago of CPB. Mortality effects of V. lecanii were different among the treatments in which the 10~8 and 10~(10) ml~(-1) conidia density were more effective on prepupae, pupae, and imago of CPB compared to other densities. Prepupae was more susceptible than pupae and imago stadia. V. lecanii showed efficacy towards the prepupae, pupae and imago stages of CPB. The results of this study indicated that V. lecanii has a high potential as a biological agent for CPB.
