Abstract
ABSTRACT The aim of this research was to know the insecticidal activity of Sphagneticola trilobata leave extract against larvae of Spodoptera litura. There are several steps in this research namely: insect rearing, plant extraction, bioassay test (toxicity, feeding activity and development inhibition test). The extract was used in this research was the methanol leave extract of S. trilobata with six concentrations level: 0.0%, 0.1%, 0.5%, 1.0%, 3.0%, and 5.0%. The results showed that the highest mortality (72%) caused by 5.0% concentration six day after application. Responds of larva feeding activity showed that the higher extract concentration applied the lower feeding activity of larvae. The higher extract concentration applied the longer development time the larvae become pupae, and pupae become adults. Nevertheless the treatments are not significant influences the measure of long and weight of pupae.
