Population dynamics of arthropods on tomato (Lycopersicum esculentum l.) in Vindhya plateau region of Madhya Pradesh

Abstract

The field experiment results on “population dynamics of different insect pest and their natural enemies on tomato” showed that the aphid population peaked in the 7th SMW (8.83 aphids/6 leaves) during Rabi Season 2021-22. Amrasca biguttula population attained its peak (6.33 jassids/ 6 leaves) during the 11th SMW. The first peak of the leaf miner population was observed (4.67 leaf miner/6 leaves) during the 11th SMW and the second during the 16th SMW. The tomato mirid bug had the highest mean population (5.80 bugs/ plant) during the 11th SMW. The damaged fruit borer (H. armigera) was first recorded during the 9th SMW and maximum fruit damage was 96 per cent during the 13th SMW. The maximum mean population of ladybird beetle (5.26 lady beetles/ plant) and weaver ant (12.06 Weaver ant/ plant) was recorded during the 11th standard week. The peak population of damselfly (2.20 damselfly/ plant), whitefly (7.83 whitefly/6 leaves) and dragonfly (2.20 dragonflies/plant) were observed during the 10th SMW
