ABSTRACT
The data on biodynamics of major pests and natural enemies on pearl millet genotype AHB-1200 Fe and its coorelation with weather parameters during nine meteorological weeks i.e. from 29th to 37th SMW indicated that shoot fly and shoot borer incidence was 8.89%. Helicoverpa larval population was 0.03 per panicle; hairy caterpillars were 0.11 per plant. Fall Armyworm damage was observed for the first time i.e. 7.22% with a population of 0.03 larvae per plant. Chaffer beetles were 0.06 per plant while Blister beetles were 0.03 per plant. The natural enemies i.e. Coccinellids (LBB) were 0.05 per plant, Chrysopids (GLW) were 0.04 per plant and Entomopathogenic Fungi were found to infect 0.02 larvae per plant. The analysis with weather parameters revealed that fall armyworm, its damage, blister beetles and entomopathogenic fungi had significant coorelation with weather parameters i.e. rainfall, temperature (maximum and minimum) and relative humidity (morning and evening). Fall armyworm and its damage, blister beetles as well as entomopathogenic fungi had moderate negative coorelation with rainfall and strong negative coorelation with temperature (maximum and minimum); while moderate positive coorelation with morning relative humidity and strong positive coorelation with evening relative humidity was observed.
