Temperature had a significant and positive effect on whitefly and thrips population with r-values of 0.86 and 0.77, respectively. Non-significant effect existed between relative humidity and insect pests population density. The combined effect of temperature and relative humidity was higher (86.50 and 75.00 percent) on whitefly and thrips and lesser (46.91 percent) on jassid population. Temperature alone showed a non-significant effect on jassid population. Confidor and Nuvacron, used on cotton, yielded the maximum mortality of jassid (88.08 and 84.17 percent), whitefly (84.83 and 83.56 percent) and thrips (88.06 and 82.99 percent), respectively.
