Each pesticide was applied @ 1. 4 ml on third instar larvae of the predator and known number of jassids with Pottar Spray Tower in three different modes. The experiment was laid out in CRD in the lab. It was found that Monocrotophos and Talstar were highly toxic giving 96-100% and 80-90% kill of the predatory larvae, respectively.
