ABSTRACT

 

FAW lures procured from AG Bio Systems Pvt. Ltd., Hyderabad (India) and placed in sleeve pheromone traps were installed six inch above the crop canopy. To evaluate the efficacy of pheromone traps with different weather parameters, the study was conducted on farmer’s maize field with five treatments viz., 5, 10 and 15 traps per acre along with recommended package (RPP) for FAW management (spraying of emamectin benzoate 5 SG @ 0.3 g/l and chloranitraniliprole 18.5 SC @ 0.2 ml/l at 30 and 50 days of sowing) with one untreated control and the treatments were replicated four times. Studies on correlation and regression analysis between 5 traps per acre and weather parameters revealed negative non-significant relationship with maximum temperature (r = -0.154) and rainfall (r = - 0.188). Among weather parameters, viz., maximum temperature (r = - 0.134) and rainfall (r = - 0.097) registered negative relationship with10 traps per acre. Whereas, same trend was noticed with 15 traps per acre which exhibited negative non-significant association with maximum temperature (r = -0.129) and rainfall (r = -0.033). However, remaining weather parameters showed positive non-significant correlation with different trap density level treatments.
