abstract
The present research work was conducted record the variability of phototactic arthropod fauna through the light trap in the soybean ecosystem at JNKVV research farm Jabalpur (M.P.). Insect pest fauna of the soybean crop collected through the light trap in JNKVV research farm during the year 2014 was documented and classified on taxonomic basis, economic aspect (crop pest) and bio control importance (parasites and predators). A total of 48 species were recorded. These phototactic insects belong to 9 orders and 31 families. Lepidoptera was the biggest order with 20 species. Other orders were Hemiptera (10 species), Coleoptera (9 species) and Orthoptera (3 species). Hymenoptera, Odonata, Isoptera, Neuroptera and Dictyoptera were the other order of minor significance. Based on economic significance this collection was represented by 34 species of harmful insects (as crop pests) 14 species of predatory and parasitic insects (useful as bio-control agents). Category of harmful insect pests includes 7 species belongs to soybean crop and remaining 27 pest species of different agricultural crops and forest trees. The present study reveals the valuable base line data on biodiversity of phototactic arthropods (insect pests) fauna of soybean ecosystem and provides broader scope of using a light trap as an Integrated Pest Management tool in soybean and other crops.
