Abstract
Four farm made natural products viz. Agniastra, Brahmastra, Darekastra, Dashparni each applied @ 10 per cent concentration and one commercial product Neem Baan containing azadirachtin @ 0.0005 per cent were evaluated for repellence and oviposition deterrence against Plutella xylostella using ‘Leaf dip’ method of bioassay under laboratory conditions. In ‘No choice’ test, repellence of natural products to adults of P. xylostella varied from 20.8–82.3 per cent up to 4h after adult release. However, in ‘Choice’ test, it varied from 10.4–70.4 per cent. Similarly, deterrence to oviposition by females of P. xylostella varied from 15.9–63.9 and 21.7–56.3 per cent up to 4h after adult release in ‘No choice’ and ‘Choice’ tests, respectively.
