Abstract
The antifeedant effect of neemazal and neemarine on the okra pest. Earias vitella was evaluated under vitro condition. The okra plants fruits were treated with five different doses of neemazal and neemarine. Ten to twelve hours starved larva were released in each replication. The maximum antifeedant activity was noted in neemazal 71.99 and 61.99% protection was recorded by the use of 2.5 and 2.0% concentration respectively and the percentage fruit consumed at 0.25% conc. Of neemarine was the lowest (20.99). A significant decrease in percent protection on of fruit up to 71.99 and 20.99% in neemazal. Neemarin against E. vitella were observed. The result also shows that both the pesticides may have significant effect on the okra fruits protection of pest E. vitella. Therefore less expensive natural pesticides could be an alternative for chemical pesticides
