摘要：Mass awareness regarding the detrimental effects of excessive use of pesti cide was generated only after the publication of 'silent spring' (Carson,1962) which made it imperative to consider some environment frien dly, safe and compatible alternatives. In the last two decades or so juvenoids have opened new vistas in that res pect. These insecticides are very much target specific, effective in small quantities and often decompose quickly (Ware,1994) .These attributes will reduce the pesticide inputs and conserve our natural flora and fauna . In holometabolous insects like Lepidoptera, only in absence of juvenile hor mone the last larval instar undergo a pupal moult by the action of ecdysone. Juvenile hormone prevents any precocious development of imaginal disks, and control the morphological, ultrastructural and physiological changes that occur during shedding of epide rmis i.e.ecdysis. This ecdysis and
