Larvicidal activity of plant extract of Triumfetta pentandra against agricultural insect pest Spodoptera litura and Helicoverpa armigera. The Plant extract in deferent solvent were prepared various concentrations for 5%, 2.5%, 1`25% and 0.625% and tested against fourth instar larvae of Spodoptera litra and Helicoverpa armigera. Then agricultural in...

Solanum pseudocapsicum L. A Potential Pesticide Against Helicoverpa armigera (Hub.) and Spodoptera litura (Fab.) (Lepidoptera: Noctuidae) T. Chinnamani, Alagarmalai Jeyasankar and Kuppusamy Elumalai Abstract: Background and Objective: Nowadays, chemical pesticides applied to control the field pests have deleterious effects on the ecosystem. Hence,...

The aim of this research works was to determine the chemical composition and insect growth inhibitory activity of ethyl acetate crude extract of Solanum pseudocapsicum fruits against the Spodoptera litura and Helicoverpa armigera. Ethyl acetate extracts of S. pseudocapsicum fruits were fractionated using Silica-gel Coloum Chromatography and analyse...

Antifeedant, larvicidal and ovicidal activities of fractions isolated from ethyl acetate crude extracts of Barleriabuxifolia leaves were tested against fourth instar larvae of Spodopteralitura and Helicoverpaarmigera. The maximum antifeedant, ovicidal and larvicidal activity was recorded in fraction III of B. buxifolia against S. litura and H. armi...

To determine the repellent and larvicidal activities of five essential plant oils such as citriodora oil (Corymbia citriodora var. C), citronella oil (Cymbopogon nardus var. L), clove oil (Syzygium aromaticum L.), Gaultheria oil (Gaultheria procumbens L) and lemongras oil (Cymbopogon citratus) against Tribolium castaneum. Repellent and larvicidal a...

To evaluate the growth and feeding inhibitory activities leaves extract of Tragia involucrata tested against third instar larvae of Achaea janata and Pericallia ricini. Feeding inhibition, larvicidal and growth inhibitory activities were tested with different solvent extracts of hexane, chloroform and ethyl acetate. Chloroform extracts showed pr...

Objective: To evaluate the antifeedant, larvicidal and insect growth inhibitory activities extracts of Pseudocalymma alliaceum tested against fourth instar larvae of Spodoptera loitfu craru (dSe. litura) and Helicoverpa armigera (H. armigera). Methods: Hexane, chloroform and ethyl acetate extracts were prepared and tested for antifeedant, insectici...

To investigate the antifeedant activity of crude extracts of Barleria buxifolia tested against fourth instar larvae of Spodoptera litura and Helicoverpa armigera. Antifeedant activity of hexane, chloroform and ethyl acetate extracts were prepared and tested against fourth instar larvae of selected insect pests. Ethyl acetate extracts of B. buxifoli...
