Fourth generation insecticide also called insect growth regulators valuable pesticide of modern era used against different pest. Novaluron & Buprofezin are the compounds of benzoil pheny urea are such insecticides inhibit the synthesis of chitin in body causing malformation of body parts as well as mouth parts. Thus they affect feeding habits as well as developmental process like embryonic and laval development. They cause the mortality of larva as well as adult due to malformed mandibls. (Ishaaya et. at (2002) reported that novaluron as a powerful toxicant for controlling lepidopteran larvae. Urs and Narsimhan (1977) tested the R - 20458 as insect growth regulator on the growth and development of tobacoo caterpillar, Spodoptera litura and observed that when 5ᵗʰ instar larvae were treated topically with different concentrations of R- 20458, the lower concentrations results malformed larva or pupa while higher concentration resulted sluggish activity in larva. Larvae also showed none feeding characters thus results the death of the moth. The present work is based on to find out the mortality of 3ʳᵈ instar larva of Euproctis icllia under pupal dip treatment, adult feeding treatment& residue film treatment method. Mitsui, Nobusawa and Fukami (1981) studied the effect of diflubenzuron on chitin synthesis and synthetase activity during the last larval instars of Momestra brassicae (L.) and reported that diflubenzuron inhibited chitinous cuticle formation.
