OVICIDAL ACTIVITY OF ORGANIC PRODUCTS AGAINST SPODOPTERA LITURA (FAB.) (LEPIDOPTERA : NOCTUIDAE)

摘要

Chemical and synthetic insecticides used for controlling Spodoptera litura (Fab.) resulted in the development of resistance to several classes of insecticides. In the present study, five organic products including cow urine,panchagavya, darekastra, agneystra, dashaparni, neem seed kernel extract (NSKE) and one biopesticide i.e., Neem Baan 1500 ppm were evaluated for their ovicidal activity at different concentrations against Spodoptera litura under laboratory conditions. Maximum ovicidal activity of100 per cent was recorded by NSKE (at 10%) and Neem Baan 1500 ppm (at 0.15 and 0.30%) followed by darekastra (61.93 at 80% cone.). The study indicated that all the test products have variable ovicidal properties and may be used for the pest control at the time of appearance of the pest.
