Pheromone traps data showed clear-cut two periods of activity of Helicoverpa armigera moths, first from 14th to 19th SWs, 2011 and second from 6th to 16th SWs, 2012. The maximum mean populations of moths/trap/week recorded in respective periods were 20.67 in 14th SW, 2011 and 32.67 in 13th SW, 2012. Correlations between male moths trapped in pheromone traps and weather parameters had positive correlation with maximum temperatures and significant negative correlation with minimum temperature and highly negative correlation with relative humidity. In case of chickpea maximum larval population was 5.67/10 plants in 11th SW, 2012 and in pigeonpea maximum larval population was 6.00/10plants in 15th SW, 2012. The larval population recorded in chickpea had positive correlation with minimum and maximum temperatures and significant negative correlation with relative humidity. In case of pigeonpea, larval population had highly significant positive correlation with minimum and maximum temperatures and highly significant negative correlation with relative humidity. Only larval parasitoid recorded was Compoletis chlorideae that caused 5.66-76.00%, with a mean of 41.21[plus or minus]5.65% parasitization. Jul 2015
