Antifeedant activity of plant extracts to an insect Helopeltis theivora.
The different solvent extracts (viz Petroleum ether Ethyl acetate and Methanol) obtained from leaves and flowers of Heliotropium indicum and Spilanthes calva were screened for antifeedant activity against Helopeltis theivora. All the six different extracts showed antifeedant activity at four different concentrations. The methanolic extracts of leaves of Heliotropium indicum and Spilanthes calva...
متن کاملThe Synergists Action of Piperonyl Butoxide on Toxicity of Certain Insecticides Applied against Helopeltis Theivora Waterhouse (heteroptera: Miridae) in the Dooars Tea Plantations of North Bengal, India
Higher efficacy of mixture of insecticides with synergists piperonyl butoxide (PB) was reported in controlling in the Dooars population of Helopeltis theivora Waterhouse. Therefore, the use of synergists as one of the countermeasures against the insecticide resistance problem of H. theivora is recommended. The combination of deltamethrin +PB (piperonyl butoxide), quinalphos +PB and imidacloprid...
متن کاملReproductive activities of Heliotropium indicum isolate against Helopeltis theivora and toxicity evaluation in mice.
A new compound E was isolated from the methanolic extract of the leaves of Heliotropium indicum by chromatographic fractionation. In the present study, the effect of the compound E on reproduction of Helopeltis theivora has been evaluated. The acute toxicity study (LD50) and sub-acute toxicity studies (haematological, biochemical and histopathological parameters) in albino Swiss mice were carri...
متن کاملTemperature dependent development of Lygus hesperus (Hemiptera: Miridae) nymphs.
Lygus hesperus Knight (Hemiptera: Miridae) is a key pest of fruit and vegetable crops, forages, and cotton (Gossypium spp.) in the western United States. Accurate models describing relationships between temperature and L. hesperus development are critical to the study of seasonal L. hesperus population dynamics. Development of L. hesperus nymphs was assessed at nine constant temperatures from 1...
متن کاملAn annotated catalog of the Iranian Miridae (Hemiptera: Heteroptera: Cimicomorpha).
An updated list of Iranian Miridae Hahn, 1833 is provided and discussed. Seven subfamilies (Bryocorinae, Cylapinae, Deraeocorinae, Isometopinae, Mirinae, Orthotylinae, and Phylinae), 140 genera, and 498 species are confirmed from Iran. Phytocoris (Stictophytocoris) meridionalis (Herrich-Schaeffer, 1835), is newly recorded from Iran. The possible presence in the country of 28 additional species ...
