Collection, isolation and bioassay studies of indigenous isolates of Lecanicillium lecanii (Zimm.) Zare and Games against Myzus persicae (Sulzer)

Reshma Gokak, SH Ramanagouda and J Jayappa

The evaluation of indigenous local isolates of Lecanicillium lecanii was determined against Myzus persicae by detached leaf smeared method. A total of three isolates of L. lecanii from the 30 samples were obtained based on their pathogenicity test against M. persicae. Among the three isolates R7BGBD (100%) and R8GAR (96.67%) showed highest mortality whereas the least mortality was found in the isolate R4HAT (56.67%) at eight days after treatment at the concentration of 2 x 10 9 cfu/1000 ml. The isolate R7BGBD was the most virulent at six and eight days after treatment, the LC50 values being 0.54 X 109 and 0.15 X 109 cfu/1000 ml, respectively. The order of virulence based on LC50 values was R7BGBD> R8GAR> R4HAT. These isolates performed better under laboratory conditions and need to be evaluated under field conditions for their promotion against sucking insect pests of various Horticulture and Agricultural crops.
