Abstract

An assessment was carried out on mass trapping of pink bollworm in cotton during 2018-2019 at Mandakhali Tq. Parbhani and in 2019-2020 at Mangrul (Bk.) Tq. Manwat on 4 ha area of Parbhani district of Maharashtra. During assessment, observations were carried out on three treatments i.e. T1 - farmers practices, T2 - IPM practices recommended by VNMKV, Parbhani and T3 – IPM practices recommended by VNMKV, Parbhani + installation of pheromone traps @ 40 /ha recommended by AAU, Gujarat. The observations at weekly interval revealed that lowest rosette flowers, Green boll damage, locule damage and adult moth catches per trap i.e. 7.45, 9.50, 8.95 and 14.00 per cent were recorded in T3 – IPM + installation of pheromone traps @ 40 /ha, respectively. Which was followed by T2 - IPM practices i.e. 9.02, 11.85, 10.01 and 12.31 per cent rosette flowers, green boll damage, locule damage and adult moth catches per trap per week, respectively. Whereas highest percentage of rosette flowers (11.25), green boll damage (13.02), locule damage (12.01) and adult moth catches (9.62) per trap per week were found in T1 -farmers practices. Considering the yield (qt/ha) and B:C ratio highest yield and benefit cost ratio was found in T3 (i.e. 18.75 qt./ha and 2.32) followed by T2(i.e. 17.45 qt./ha and 2.12) whereas lowest yield and benefit cost ratio was found in T1 (i.e. 16.20 qt./ha and 1.88). From the study it is concluded that treatment T3 – IPM practices recommended by VNMKV, Parbhani + installation of pheromone traps @ 40 /ha recommended by AAU, Gujarat was found superior over other treatments.
