“…Discovery of synthetic pyrethroids was solely based on natural prototype pyrethrin from the plant Chrysanthemum cinerariaefolium (Matsui and Yamamoto, 1971). In addition, several plants have also been documented as insect control agents (Prajapati et al, 1998;Tripathi et al, 1999).…”

Crude ethanolic extract of the stem bark of Terminalia arjuna (Combretaceae) and its three compounds namely arjunic acid, arjungenin and arjunetin were evaluated for antifeedant, growth inhibitory and oviposition-deterrent activities against a lepidopterous insect Spilarctia obliqua. The compound arjunetin showed highest growth inhibitory and feeding-deterrent properties with a growth inhibition (GI(50)) and feeding-inhibition (FD(50)) of 188.5 and 287.1 micro g/g diet respectively. Oviposition bioassays indicated no oviposition-deterrence in any of the compounds tested. The structure-activity relationship study indicated the importance of a glycosidation linkage in arjunetin.

Vector control is a serious concern in developing countries. Over the past two decades, phytochemicals have received progressively more attention as insecticide alternatives, and they have recently become the focus in the concept of integrated vector control. α‐Amyrin acetate, the n‐hexane fraction of acetone extract from the leaves of Catharanthus roseus, was evaluated for its larvicidal, pupicidal and fecundity effects as well as insect growth regulator activity against the malaria vector Anopheles stephensi Liston. The highest concentration of 1 p.p.m. produced 100% mortality in first to second instars and 94% mortality in third and fourth instars. In addition, the duration of larval instars and the total developmental time were prolonged, while female longevity and fecundity were markedly decreased. The suppression of pupation and adult emergence was probably due to its action similar to juvenile hormone analogs in combination with growth regulator activity and toxicity, which reduced the overall performance of the malaria vector An. stephensi.

Five doses of each of the oils 2.5, 2.0, 1.5, 1.0 and 0.5µl were topically applied to the thoracic region of cold immobilized individual fourth instar larvae by microapplicator syringe (Prajapati et al, 1998, Pavela, 2005., Tandon et al, 2008. Three replications were maintained.…”

The present study was conducted to evaluate the insecticidal and growth regulatory activities of clove oil, Syzygium aromaticum and camphor oil, Cinammomum camphora against Bihar hairy caterpillar, Spilosoma obliqua. The fourth instar larvae were subjected to topical application by microapplicator syringe with doses of 2.5, 2.0, 1.5, 1.0 and 0.5 Î¼l/larva. Camphor oil was most effective at 2.5, 2.0 and 1.5Î¼l dose causing death of larvae ranging from 76-90%. It showed a strong growth regulatory activity with no adult emergence at the highest concentration. Clove oil was effective in reducing adult moth population to 27% at highest dose of 2.5 Î¼l. Only this dose could cause larval mortality of about 60%. The study shows potential of these oils to be utilized as insecticides or antibiosis mechanism to suppress the population of S. obliqua.
