Abstract

This research aims to analyze the effect of length of exposure to sunlight and the type of storage container on the effectiveness of NPV in controlling Spodoptera litura. NPV isolates were exposed to direct sunlight for 1, 3, 6 hours in glass and plastic vial containers. The isolate was infected to 3rd instar S. litura larvae using feed contamination technique. This research implemented a factorial Completely Randomized Design (CRD), with 6 treatments and control. The results showed that NPV isolates with MK.1 and MP.1 treatments were effective in producing a percentage of larvae mortality and were able to suppress the formation of pupae and imago with a mortality percentage of 84,2 % and 71,4 % at 72 hours after aplication. The best LT_50 value is found in the MK.1 treatment, which is 2.4 days or at 72 hours after application.
