“…It selectively inhibits chitin synthesis in insects but not in fungi (Post and Vincent, 1973;Ishaaya and Casida, 1974;Post et al, 1974). The insecticidal activity of these compounds can be observed as defective chitin formation, abnormal endocuticular deposition, and abortive molting (Mulder and Gijswijk, 1973).…”

“…Insect growth regulators (IGRs) have received a great deal of attention in the last two decades as promising insect control agents (Retnakaran et al 1985) because of their unique mode of action of disrupting the metamorphic development, higher selectivity and less persistence in the environment (Post-and Vincent 1973;Mulder and Gijswijt 1973). In addition, many new IGRs currently under development have low mammalian toxicity and are potentially compatible with natural enemies and safer to economically important insect species (Staal 1975).…”

Hatchability of eggs of Culex quinquefasciatus, Aedes aegypti and Anopheles stephensi was studied by exposing freshly laid (0-1 h) and older (12-18 h) eggs to varying concentrations ((}-()()()1-1{) mg/l) of 6 insect growth regulators viz. OMS 3019, OMS 3007, OMS 2015, OMS 3031, OMS 3013 and OMS 3009. In all the 3 species, dosage dependent response was observed. The response was also dependent on the age of eggs. Among the 6 IGR compounds OMS 3031 was found highly active resulting in maximum reduction in hatching of freshly laid eggs of Anopheles stephensi (99·95%) followed by Aedes aegypti (89'9%) whereas 50% inhibition in hatching occurred in older eggs of Culex quinquefasciatus exposed to OMS 3009 at the same dosage. Dose, age and dose and age dependent hatching was evident in eggs of the 3 test species exposed to insect growth regulators OMS 3019, OMS JOB and OMS 2015. Higher proportion of unhatched eggs with varying abnormalities was noticed in test species. Percentage mortality observed was higher in first instar larvae hatched from treated eggs reared in untreated water. Therefore, insect growth regulators have great potency in suppressing the population by affecting hatching of mosquito eggs in addition to inhibition of adult emergence, thus providing a useful tool for integrated vector management.

“…® After 2 days, the radioactivity in the nymph bodies was analyzed according to the method of Post and Vincent. 8 ) The biosynthesis of [14C]chitin from [14C(U)]glucose was inhibited by 47% in the nymphs treated with 10 ppm of buprofezin, more than 70% of which eventually failed to emerge (Table I). The radioactivity in other fractions was less affected by buprofezin.…”
