Abstract
The population dynamics of Aphis gossypii (Glover), Dysdercus koenigii Fabr. and Amrasca biguttula biguttula (Ishida) with respect to meteorological parameters on okra was conducted at the experimental farm, ICAR Research Complex for NEH Region, Mizoram Centre, Kolasib, Mizoram. The results revealed that a decrease in minimum temperature and minimum relative humidity and maximum relative humidity and increase in maximum temperature by 30 to 40% favour the population buildup of A. gossypii. Whereas an increase in temperature coupled with dry weather and decreased relative humidity favoured the build-up of A. biguttula biguttula. Peak population of D. koenigii was recorded as soon as maximum and minimum temperature was below 24 and 320C, respectively and minimum relative humidity and maximum relative humidity crossed 58 and 81%, respectively.
