Abstract

To investigate the effect of azadirachtin on different stages of the sunn pest, Eurygaster integriceps Put. (Het., Scutelleridae) in the laboratory, a commercial neem insecticide (NeemAzal T/S) was applied at dose of 0.5 % by dipping insects. No effect was observed for 1. instar nymphs at 1 day after application, although adults had slightly effect (20 %). Adults and nymphs were infl uenced 7 days after the treatment and mortality rates for adults and nymphs
were recorded 44.0 and 51.9 %, respectively. The hatching of treated eggs was reduced than control. These results indicate that NeemAzal T/S may be used in integrated sunn pest management, but should be evaluated for fi eld efficacy.
