ABSTRACT: The effects of CB1, CB3, CB5, CB8 and CB12 cotton varieties on the growth, morphometric parameters and life length of the armyworm Spodoptera litura Fabricius (Lepidoptera: Noctuidae) were studied under laboratory conditions. The growth of the larvae differed significantly and was the highest on CB8. The larvae that fed on CB1, CB3 and CB12 revealed statistically similar and lower growth rate. The morphometric parameters of S. litura as a result of feeding on five cotton varieties revealed that the larger egg masses were laid on CB5. the varieties showed statistically significant effects on length, width and weight of different larval instars. the larvae fed on CB8 molted to bigger-sized pupae, and emerged as heavier adults. the life lengths of the male and female insects were longest on CB8 however the female showed statistically similar result on CB5. the CB8 followed by CB5 revealed suitability as the host plant of S. litura, and such varieties are less suitable for cultivation in areas where army worm is a major pest.
Keywords: Cotton varieties, Spodoptera litura, morphometric, growth, life length.
