Abstract:
To study and monitor the adult population of Fall armyworm during kharif, 2021 throughout the entire season of Maize, pheromone traps were installed at farmers field’s Chandragiri, Narayanavanam and ARS Perumalpalli. The highest trap catches in the entire season with respect to Chandragiri was noticed at thirty five days after sowing at V8 and V9 stages viz., 81.49 moths / trap / week followed by trap catches in Narayanavanam which recorded 77.99 moths / trap / week at twenty eight days after sowing during V5, V6 and V7 stages. In ARS perumalpalli at twenty one days after sowing during V3 and V4 stages trap catches recorded 22.67 moths / trap / week. The maximum overall mean moth trap catches during kharif, 2021 (Table 1) was observed in Pheromone traps at Chandragiri (26.96 moths / trap / week) followed by Narayanavanam (21.94 moths / trap / week) which were statistically found to be at par with one another. Least mean moth trap catches were observed in ARS Perumalpalli (10.13 moths / trap / week) which differed statistically.
