Abstract
The present study may be the first attempt in Egypt which devoted to studying the biological aspects of fall armyworm, Spodoptera frugiperda (J.E. Smith). The study was conducted under laboratory conditions (26 ±1°C and 65 % R.H.) at the Department of Zoology, Faculty of Science, South Vally University, Qena Governorate, Egypt. The results included both hatchability (%) and incubation period (days) for egg stage; larval duration (days), pupation %, larval mortality %, malformed larvae %, and normal larvae % for the larval stage. While, the pupal duration, normal pupae %, malformed pupae %, pupal weight (gm), malformed pupae %, pupal mortality %, and emergence % for the pupal stage. Adult malformation %, sex ratio %, adult longevity (days), male longevity, female longevity, pre- oviposition period, oviposition period, post -oviposition period, fecundity (No. eggs/ ♂) and fertility % for the adult stage. The study of the biological aspects of the fall armyworm as a new invasive pest came to Egypt from the of South Africa countries is very important in order to determine the stages of life history to contribute to the planning IPM strategies for this dangerous pest in the absence of any local information about it
