Abstract

A new technology to improve quality and performance of botanical insecticide is needed urgently. Nanoencapsulation is a method to coat plants active substances by the polymer wall layer so that it produces nanoparticles. To examine effectiveness of this technique, we evaluated efficacy of encapsulated neem seed extract towards antifeedant activity and larvae mortality of armyworm Spodoptera litura in a laboratory. The research was conducted in several steps, i.e., rearing armyworm in laboratory, extraction of neem seed, encapsulation of neem seed extract, and efficacy test the encapsulated neem seed extract against the mortality of armyworm in laboratory. The result showed that the encapsulated neem seed extract 30% exhibited the highest antifeedant activity to S. litura., while 10% concentration of this botanical insecticide inflicted 64.75% larvae mortality.
