Abstract

Bemisiatabaci Genn is a primary soybean pest in Indonesia. This pest infests soybean leaves, causing direct damage in the form of wilting leaves and necrosis, and indirect damage by the formation of powdery mildew and viral infections which decreases soybean production. Pest control using pesticide has diminishing effectiveness and also causes collateral pollution, which necessitate an alternative method of controlling B. tabaci. One such method is the use of entomopathogenic fungi Lecanicilliumlecanii. This research aims to find the effect of conidia density of the entomophatogenic fungiVerticillium(=Lecanicillium) lecanii (Hypocreales:Clavicipitaceae) Zimm towards Bemisiatabaci Genn under field conditions. This research uses the split plot method, with two factors, six treatments, and three replications. The treatment was done by spraying L. lecanii 107conidia/ml or 109conidia/ml every week or two weeks on soybean leaves. The results showed that L. lecanii application significantly decreased B. tabaci population. Conidia density of 109conidia/ ml per week resulted the most significantly effective decreasing of B. tabaci population.
