摘要:
Ethanolic extracts of fresh neem seeds were formulated as aqueous suspensions and defatted ground neem kernels were formulated as non‐wettable dusts for greenhouse studies with fall army‐worm larvae,Spodoptera frugiperda(J. E. Smith). First stage larvae of the fall armyworm were fed neem‐treated Golden Bantam sweet corn. The antifeeding potency of 0.2 and 0.4% aqueous solutions of the neem seed extract was maintained for at least 21 days. Tests with formulated dusts showed moderate activity against 1st stage fall armyworm larvae.
