at 07.00 WIB and 15.00 WIB with 2 days interval. The research parameter is the
preyed pest by predator. Data analysis by using unpaired t test with
significance level of 1% The results
showed that Synharmonia conglobata
Linnaeus has predation
toward white back
pest (Sogatella furcifera Horvath).
From data, the
predator prey pest
in the light
