Abstract:
The present experiment was conducted under the study on scope and use of light trap as IPM tool in chickpea ecosystem. Documentation of information was done on biodiversity of phototactic insect pests in chickpea ecosystem at Jabalpur. Standard design of Jawahar light trap with 80 W mercury vapor lamp was used to record the insect catches in chickpea crop from October 2015 to April 2016. Data was classified on taxonomic and economic aspect as crop pests. In all 25 species of insects were collected during the cropping season of chickpea. These insect species belongs to 6 insect orders and 14 families. Lepidoptera was the largest order with 11 species. Other major orders were Hemiptera (7 species), Coleoptera (3 species) and Orthoptera (3 species). Isoptera (1 species) were the other orders of minor significance. Helicoverpa armigera and Agrotis ipsilon were active from October to April with peak catches during 12th & 15th and 5th, 14th &17th standard meteorological weeks, respectively. Correlation regression study with weather factors exhibited that maximum temperature and minimum temperature had a positive effect while morning relative humidity and evening relative humidity showed a significant negative influence on moth catches of Helicoverpa armigera. Maximum temperature, morning and evening relative humidity exhibited the significant positive and significant negative effect, respectively on A. ipsilon.
