Arun Kumar

Abstract :

Experiment were conducted to study the bioefficacies of different neem based pesticides that affected the larval and the nymph development of E. vitella and D.koenigii fed on okra fruits. Neem based pesticides (neemazal, neemarine, bioneem, neemgold, nimbicidine and achook) direct toxicity effect on E. vitella and D.koenigii . The result on insecticidal properties of six neem based pesticides against E. vitella and D.koenigii have shown that neemazal at the dose 2% was mast effective in resulting the mortality percentage of 94.97 and 86.14 in E. vitella and D.koenigii respectively . However achook shows low mortality in 60.27 and 61.77 in higher percentage(2%). The toxicity effectiveness on the basis of the mortality thus could be arranged in descending oder of follows neemazal>neemarine> bioneem> neemgold> nimbicidine and achook.
