Field experiments was conducted during kharif season 2014-2015 to study the influence of meteorological factors on the incidence of major pests of cotton. Incidence of aphids was initiated in 32nd MW ( leaf) and aphid population was lowest in 42nd and 43rd MW ( leaf). It has attained its initial peak during 32nd MW ( leaf) which was favored by min. temp. of and max. temp. of with morning % and evening % humidity along with mm rainfall. Incidence of leaf hoppers was initiated in 34th Mw ( leaf) and thereafter continued up to 42ndmw with disappearance in 43rdand 44th MW. It reached its peak during 36th MW ( leaf) which was favored by min. temp. of and max. temp. of oC with morning % and evening % humidity along with mm rainfall. | Influence of weather factors on the incidence of major pests and its predators of cotton
