abstract
Field experiments was conducted in Rabi season during 2017-18 at the farm of Department of Agricultural Entomology, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. (Maharashtra) to study the seasonal incidence of major insect pests on cauliflower and their correlation with weather parameters. The incidence Aphid B. brassicae (maximum 120 per leaf during 51^nd SMW), diamondback moth P. xylostella (maximum 7.82 larvae/plant in 2^nd SMW),leaf webber C. binotalis (maximum 3.00 larvae/plant in 2^nd SMW), tobacco leaf eating caterpillar S. litura(maximum 2.0 larvae/plant during 2^nd SMW), Green semilooper Trichoplusia ni(maximum 1.06 larvae/plant in 3^rd SMW),Tussock moth Orgyia spp (maximum 0.85 larvae/plant in 2^nd SMW) and Head borer Hellula undalis (maximum 2.50 per cent in 8^th SMW). The peak activity of maggots of syrphid fly and mummified aphids were observed 4.52/plant and 24.88/plant during 52^nd and 51^st SMW respectively.the correlation of aphids, diamondback moth, leaf webber, semilooper, tussock moth and head borer were significant with minimum temperature, evening relative humidity, minimum temperature, maximum temperature, max. and min. temperature and maximum temperature respectively. correlation of syrphid fly and mummified aphid were significant with minimum temperature and evening relative humidity.
