Abstract
The insecticidal effect of neem (Azadirachta indica) seed oil was seen on the preimaginal stages, oviposition and Bhindi Yellow Vein Mosaic virus transmission by whiteflies Bemisia tabaci. Neem oil had retarded all preimaginal stages of whiteflies on stunnhemp plants. The emulsifiers soap and detergent and neem soap were inhibitory to the 4th nymphal instar only. Neem oil reduced oviposition and inhibited the development of nymphs beyond the 2nd instar. Transmission of virus was reduced by neem oil treatment of plants.
