Arthropod Diversity in Brinjal Ecosystem and its Relation with Weather Factors in Western Uttar Pradesh

Twenty two arthropods species were recorded in brinjal ecosystem in western Uttar Pradesh. On the basis of their nature of damage/activity, they have grouped in to sap suckers leafhopper, Amrasca bigutulla bigutulla (Jassidae: Hemiptera), cotton aphid, Aphis gossypii (Aphididae: Hemiptera), whitefly, Bemisia tabaci (Aleyrodidae: Hemiptera), pentatomid bug Aspongopus janus (Pentatomidae: Hemiptera), green bug, Nezara viridula (Pentatomidae: Hemiptera), cow bug, Phenococcus insolitus. Defoliators hadda beetle, Epilachna vigintioctopunctata (Coccinellidae: Coleoptera), Ak grasshopper, Poikelocerus pictus; surface grasshopper Chrotogonus sp. (Acrididae: Orthoptera), leaf roller, Eublema olivacea (Noctuidae: Lepidoptera), leaf webber, Psara bipunctalis (Pyraustidae: Lepidoptera), tobacco caterpillar, Spodoptera litura (Noctuidae: Lepidoptera). Borers; shoot and fruit borer, Leucinodes orbonalis (Pyralidae: Lepidoptera), stem borer, Euzophera particella (Phycitidae: Lepidoptera). Incidental pest; gundhi bug, Leptocorisa acuta (Coreidae: Hemiptera). Natural enemies; coccinellid beetle, Coccinella septempunctata and Cheilomenus sexmaculata (Coccinellidae: Coleoptera), braconid wasp, Bracon spp. (Braconidae: Hymenoptera) and predatory spider, Oxiopes sp. (Salticidae: Arnae). Other arthropods; honey bee, Apis spp. (Apidae: Hymenoptera), black ant, Camponotus sp. (Formicidae: Hymenoptera) are also appeared in the brinjal ecosystem. Abiotic factor i.e., temperature, R.H., sunshine hours, rainfall were played important role in the population fluctuation of these arthropods during 2005–06 and 2006–07.
