Abstract:

Field investigation was carried out during rabi seasons of 2017-18 at the farmer’s field, Allengmora, Jorhat to study the effect of weather parameters on population buildup of some predators on brinjal ecosystem. Correlation studies revealed a significant positive association of coccinellid predators with maximum temperature (r= 0.669). Moreover, all the parameters were showed a positive association with coccinellids except average relative humidity (r= -0.259) which showed a negative impact. However, population buildup of spiders influenced by maximum temperature (r= 0.242), minimum temperature (r= 0.106) and bright sunshine hours (0.373) positively, but, average relative humidity (r= -0.449) and total rainfall (r= -0.149) showed a non-significant negative impact during the present study of investigation.
