Abstract

Neem extract possess important bioactivities such as insect repellent, antifeedant, growth inhibitor, and other insecticidal properties, while curcumin has many bioactivities as antioxidant, antiinflamation, antibacterial, as well as anticancer. Both natural substances were mixed as botanical insecticides formula. Its efficacy against bean pod sucking bugs in vitro were evaluated. Several stages were done in this research, i.e. neem leave extraction, curcumin extraction, mixed formula production, and efficacy evaluation of mixed formula against bean pod sucking bugs in laboratory. The result of research showed that the mixed formula of the botanical insecticides containing neem leaves extract and curcumin caused mortality of bean pod sucking bugs in vitro significantly. The mortality percentage of bugs was up to 96, 25%. Therefore, it is emphasized that mixed formula of botanical insecticides containing natural substances is an eco-friendly product for agriculture.
