Abstract: The present studies were undertaken at Department of Entomology, College of Agriculture, Dapoli (M.S.) during 2017-18 to know the biology of Spodoptera litura (Fab.) on different host plants under laboratory condition. The data on comparative biology of S. litura on different hosts inferred that, the minimum larval development period of 11.67 days was noticed on castor, whereas, it was maximum (17.33 days) on tapioca. The minimum pre-pupal (2.00 days) and pupal period (7.33 days) were recorded on castor, while were maximum (3.00 days pre-pupal and 11.67 days pupal period) on tapioca. The pupal weight was maximum on castor i.e. 0.28 g and minimum on cowpea (0.19g). The maximum pupal success of 86.67 percent was observed in larvae fed on castor, whereas, it was significantly lowest on tapioca leaves (46.67%). Highest adult weight was found on tapioca leaves (0.20g) followed by groundnut (0.18g) and the lowest adult weights were recorded on Mulberry and cowpea (0.08g each). Among the eight hosts the adult longevity was recorded maximum on castor and sweet potato i.e.7.67 day’s each and minimum on tapioca (5.33days). The larvae fed on sweet potato leaves supported highest adult success i.e. 73.81 percent and lowest mean adult success was observed on tapioca (35.00%). The total development period was significantly highest on tapioca (37.00 days) and it was found to be minimum on castor (28.33 days). The maximum mean fecundity was 3074.00 eggs per female on castor host, whereas, minimum with 622.00 eggs per female on tapioca host. The sex ratio of female to male was observed as 1:0.7, 1:0.5, 1:0.6, 1:0.8, 1:0.6, 1:0.5 and 1:0.7 on castor, mulberry, okra, sweet potato, taro, groundnut and tapioca, respectively. The male biased ratio was only observed on cowpea (1:1.2).
