Abstract:
The study of effect of biotic and abiotic factors on Spodoptera frugiperda in Parbhani, Marathwada region was carried out at the Department of Agricultural Entomology, VNMKV, Parbhani during Rabi 2021-22. The seasonal incidence results showed that the population of Fall armyworm (larvae per ten plants) ranged between 0-13.5 and first appearance was noticed in 1^st SMW (1.5). Thereafter, it increased progressively and peaked in 11^th SMW (13.5). The population of sucking pests on maize was negligible. The first appearance of natural enemy, Coccinellid beetles (grubs and adults per plant) was noticed in 1^st SMW (0.13) while they peaked in (0.45) in 11^th SMW. The correlation study of weather parameters with Fall armyworm and Coccinellid beetle showed significant negative correlation with evening relative humidity.
