Impact of Abiotic Factors on Population Dynamics of Leaf Miner, Aproaerema modicella D. and Its Natural Enemies in Groundnut

Groundnut leaf miner (Aproaerema modicella. D.) is an important feeding insect in groundnut that significantly reduces the pod yield up to 50 per cent. The growth and development of this pest closely associated with abiotic weather parameters prevailing a particular location. Due paucity information available on population dynamics factors, study was undertaken Erode district Tamil Nadu during Summer, 2023. damages were recorded through fixed plots survey adult moth activities monitored pheromone traps at weekly intervals. From it found that, incidences observed from 30 days after sowing. highest mean damage (17.84%), catches (58.38 nos./5 traps), coccinellid beetle (4.70 nos./10 plants) spider (5.17 9th SMW. Whereas, rove maximum (4.62 10th correlation revealed temperature had positive rainfall negative populations its natural enemies. multiple linear regression analysis indicated together 66.00 95.00 cent influence enemy population. present clearly levels related prevailed area entire crop duration. Better understanding factors resulted better management more net profit for growers.
