Effect of abiotic factors on population dynamics of Thrips tabaci Lindeman infesting Bt. cotton

Patel KR, Shah KD, Ghelani YH, Kaneria PB and Patel MM

Present investigation on population dynamics against Thrips tabaci Lindeman infesting Bt cotton. Dominant invertebrate animal, insect, have capacity to change their behavior and habitat with the changing of the environment and so, it is necessary to see the impact of changing pattern in Abiotic factors on Thrips tabaci Lindeman infesting Bt cottonwith provide information regarding this utility. The incidence of thrips was commenced from fifteen days after sowing (DAS) i.e., 3rd week of July and continued till third week of November (47th SMW)) i.e. 125 DAS which was ranged from 0.96 to 27.96 thrips/three leaves. The infestation showed its peak showed its first peak (27.96 thrips/3 leaves) during 3rd week of August i.e., 34th SMW. After reaching its peak, thrips population was continuously decreased. Association between thrips infestation and weather factors indicated that there was negative significant impact due to maximum temperature [r = -0.570*] on incidence of thrips. There was a significant positive correlation between thrips and morning relative humidity [0.562*], Rainfall [0.768*] and evening relative humidity [0.574*].
