Abstract:
The investigations conducted at Research Farm of Department of Agricultural Entomology, College of Agriculture, Latur (VNKMV, Parbhani) during rabi season 2020-2021 revealed that R. maidis reached its peak population in 7^th SMW (70.8 aphids per plant) during rabi season. Correlation studies evidenced that none of the weather parameters had significant effect on population of R. maidis. N. viridula reached its peak population in 3^rd SMW (0.92 bug per plant) during rabi season. Correlation studies evidenced that before noon relative humidity and afternoon relative humidity had significantly direct positive effect on population of N. viridula, while wind speed had significantly negative effect on N. viridula population. P. perpusilla reached its peak population in 2^nd SMW (0.95 adult per plant) during rabi season. Correlation studies revealed that before noon relative humidity correlated positively, whereas wind speed correlated negatively with population of P. perpusilla. Spiders reached its peak population in 7^th SMW (5.00 spiders per quadrat) during rabi season. Correlation studies revealed that minimum temperature had negative relationship with population of spiders. Ladybird beetles and Earwig reached their peak population in 7^th SMW (20.00 beetles per quadrat) and in 5^th SMW (11.00 earwigs per quadrat) respectively during rabi season Correlation studies revealed that the weather parameters did not show any significant influence on population of ladybird beetles as well as earwigs.
