Abstract
The adult abundance of Spodoptera litura in pheromone traps was recorded during 19th standard week which continued up to 43rd standard week, exhibiting three ‘V’ shaped oscillations during the period. Thereafter, a sharp decline was noticed and population ceased completely from 49th standard week onwards up to 5th standard week. Peak larval population on tomato was noticed in 25th standard week whereas, in cauliflower the larval population attained its peak during 43rd standard week (43 larvae/10 plants). The weather parameters were correlated with insect pest incidence and was found that the number of moths/trap/week exhibited significant positive correlation with maximum (r = 0.813) and minimum (r = 0.805) temperatures. The combined influence of the weather parameters strongly influenced the population build up of the pest with the coefficient of determination, R2 values of 0.75 (moth catch), 0.82 (larval population on tomato) and 0.72 (larval population) on cauliflower
