[PDF][PDF] Prediction of Helicoverpa armigera (Hubner) larval population using weather based forewarning model in soybean
Weekly larval populations of pod borer, Helicoverpa armigera (Hubner) collected from 20
districts of Maharashtra under Crop Pest Surveillance and Advisory Project (CROPSAP)
during 2010-2015 were analyzed to work out the effect of weather variables on the
incidence of this insect on soybean. The appearance of larva was observed throughout the
soybean growing season, and the peakincidence was observed during third week ofAugust
to first week of September (34-35 SMW). The correlation analysis of the data revealed that …
