Pardosa pseudoannulata and Menochilus sexmaculatus are two predators of the brown planthopper (BPH, Nilaparvata lugens, Hemiptera: Delphacidae) in rice fields. The research aimed to determine predation competition model P. M. on different BPH densities. This study used a completely randomized design (CRD) factorially. first factor was difference predator species (P. pseudoannulata, sexmaculatus...

the effect of two insecticides, imidacloprid and pyriproxyfen, were investigated on some biological parameters of ladybird beetle menochilus sexmaculatus (f.) (coleoptera: coccinellidae) under laboratory condition. theladybird beetle were exposed to insecticides by ingestion of the common pistachio psylla, agonoscena pistaciae burckhardt and lauterer (hemiptera: psyllidae) (prey). for imidaclop...

Mate choice results from the sensory or behavioural properties that cause individuals to mate with some phenotypes and not others. It can result in direct indirect (genetic) benefits. also be influenced by various abiotic biotic factors including mating system. Here, we investigated how system of ladybird, Menochilus sexmaculatus, influences affects time commencement mating, copulation duration...

All the life stages of the reduviid predator Rhynocoris marginatus (Fab.) were released (30, 50 and 70 Days After Seedling Sowing -DAS) into the groundnut field at 5000/hectare. Spodoptera litura (Fab.), Helicoverpa armigera (Hubner), Atractomorpha crenulata, Chrotogonous trachypterus, Aphis craccivora, Mylabris pustulata and Mylabris indica were observed during the study period.
