Abstract:
Major activity period of H. armigera (Hubner) was observed from 45^th SMW to 17^th SMW. P. orichalsia (Fabricius) was observed from 47^th SMW to 17^th SMW. S. litura (Fabricius) was appeared during 47^th SMW and was continuously observed till crop harvesting. L. orbonalis (Guenée) was recorded during 47^th SMW. After the appearance of moth in trap catches, a gradual increase and decrease trend was observed from 48^th SMW to 10^th SMW. Activity of P. xylostella (Linnaeus) was observed from 47^th SMW to 17^th SMW. Among all the abiotic factors, maximum temperature. minimum temperature, were showed significantly positive correlation with H. armigera (r = 0.78* and 0.59 = byx), (r = 0.79* and 0.66 byx). P. orichalsia (r = 0.67* and 0.12 = byx), (r = 0.68* and 1.35 = byx). S. litura (r = 0.84* and 0.56 = byx). (r = 0.85* and 0.62 = byx). L. arbonalis (r = 0.84* and 1.20 = byx). (r = 0.85* and 1.34 = byx) and P. xylostella (r = 0.66* and 1.20 = byx), (r = 0.68* and 1.35 = byx) while morning and evening relative humidity were showed significantly negative correlation with H. armigera (r = -0.64*and -0.15 = byx), (r = -0.63* and -0.12 = byx). P. orichalsia (r = -0.73* and -0.42 = byx), (r = -0.72* and -0.36 = byx). S. litura (r = -0.77* and -0.17 = byx). (r = -0.79* and -0.15 = byx), L. arbonalis (r = -0.73* and -0.34 = byx), (r = -0.73* and -0.29 = byx) and P. xylostella (r = -0.71* and -0.42 = byx) (r = -0.71* and -0.35 = byx).
