Abstract

Effects of neem-extracts on cater pillars of the gypsy moth, Lymantria dispar L.

The effects of neem extracts(Azadirachta indica) (0.02%; 0.2% 0.5%) were tested on caterpillars of the gypsy moth (Lymantria dispar). The laboratory experiments showed, that these concentrations suppress the development and prohibit the moultin of caterpillars. The mortality reached 100% in all experiments. Addition test carried out under field conditions indicated that the activity of neem extract sprayed on oakleafs(Quercus robur) remained unchange after 12 days of application.
