Abstract

This study was conducted to monitor the population dynamics of major insect pest of agriculture ecosystem through light trap at the agriculture farm of GAASC ,Baitadi,during the winter of 2018.The main aim of this study was to determine the status of phototatics insects pest of the farm locality.. Light trap with a 100Watt filament bulb was installed at the site at college boundary, vegetable field and wheat field for trapping purpose. The observation was done every day and data was weekly record their status and occurrences. Overall nine insect species were observed and among them click beetle(Agriotes spp.) population was observed maximum compared to other species.Insects occurrence in vegetable field is dominated by click beetle followed by moths(Pieris canidia)and cabbage semi looper(Trichoplusia spp).The total 289 of 6 different species were found from vegetable fields. Trap installed on Agronomy farm contributes clickbeetle (Agriotes spp.)The most followed by Greenleaf hopper(Nephotettix spp)., Pink borer(Chilo partellus), wasp(Vespa spp.) and grasshopper(Hieroglyphus banian),total 152 of 5 different species were found until 15 week of monitoring. Similarly, trap installed in open field obtained total 176 out of which 68 were click beetle (Agriotes spp.),47 pink borer (Chilo partellus),40 moths (Pieris canidia) and 21 wasps (Vespa spp.).
