Abstract
The various aspects of the biology of the cotton leaf –worm ,Spodoptera littoralis (Boisd.) ((Lepidoptera: Noctuidae)where it fed on four different vegetable plants okra , squash,cabbage and green beans to study the effect of these host plants on the developmental stages, fecundity and life table parameters under laboratory conditions of ( 25±1°C) and 75±5%R.H.Obtanied results and statistical analysis cleared that the developmental stages, fecundity and life table parameters affected by different hosts whereas the life cycle(39.6±1.46±2.3, 34±2.07 and35.8±4.08) ,oviposition period (5.4±1.1, 9.2 ±1.3, 9.4±1.14&9.6±1.5) and an averages numbers of eggs (660,448,860&391)green beans, okra, cabbage and squash respectively. okra and squash provide the shortest generation time (G) and longevity as well as greatest fecundity (F)which increased (exprm)to . okra and squash was the most suitable tested host, and cabbage was the least suitable one green beans was of intermediate suitability.
