A study was conducted during the kharif season of 2013 and 2014 for knowing the effect of new insecticides for the control of sucking pests in moong bean (PDM11). Population of thrips, jassid and white fly were recorded in natural field condition with crop age and found that the population of entire three pests such as jassid (6.19/6 leaves), thrips (7.39/6 leaves) & whitefly (10.54/6 plants) increased with increase the crop age up to 48 days after sowing. Reproductive stage was more vulnerable than vegetative and maturity stage. Among the insecticides, thiamethoxam was found more effective (0.83 jassid/6 leaves) Followed by imidacloprid (0.95/6 leaves) and acitamiprid (1.07/6 leaves) in the year 2013 against jassid. However, same trend of result was obtained in the year 2014. Imidacloprid significantly showed better effect to control the thrips population, which was 1.00 thrips /6 leaves in 2013 and 1.46 /6 leaves in 2014, respectively. White fly population significantly decreased by the application of thiamethoxam (2.83 and 1.69 /6 plants) followed by imidacloprid (2.94 & 1.88/6 plants) and acetamiprid (2.97 & 2.00 /6 plants) during the seasons 2013 and 2014. Highest population of all the three sucking pests was noted in Control plot. Significantly maximum yield in 2013 was found in imidacloprid treated plot (15.81 q/ha) followed by thiamethoxam(15.69 q/ha) in comparison to monocrotophos (12.73 q/ha ) and fipronil (11.51 q/ha). However, in 2014, thiamethoxam showed better performance in increasing the yield which was 15.47 q/ha followed by imidacloprid (14.15 q/ha). Neem oil and chloropyriphos had least effect on increase the yield in both the crop seasons. Effect of trizophos (12.63 q/ha), fipronil (12.58 q/ha) and monochrotophos (12.12 q/ha) in enhanced the productivity were at par in 2014. In control plot there was only 5.78 and 6.32 q/ha yield, respectively during 2013 & 2014 crop seasons.
