Abstract

Spodoptera litura Multiple Nucleopolyhedrosis Virus (SpltMNPV) is one of insects pathogens that infect armyworm so they can be as a natural armyworm enemies. The SpltMNPV are sensitive against the sun so that could reduce its pathogenicity level. This research aimed to determine the effective concentration of bengkuang flour to protect SpltMNPV against the sun exposure to maintain the length of life against armyworms. This research used a completely randomized design (CRD). The treatment consisted of one factors, namely bengkuang flour concentration with 4 treatments. The treatments were SpltMNPV + kaolin 1:4 added by bengkuang flour concentrations 0%, 1%, 2.5%, and 5% respectively. The result showed that SpltMNPV + kaolin 1:4 added by bengkuang flour concentrations of 0%, 1%, 2.5%, and 5% affected the length of armyworm life in 7 day, 7 day, 6 day, and 5 day respectively with percentage of armyworms 25%, 25%, 20%, and 5% respectively. The 5% concentration of bengkuang flour was the effective concentration to protect of SpltMNPV against the sun exposure.
