The fall armyworm, Spodoptera frugiperda (J. E. Smith, 1797), is the most important noctuid pest in the Americas and has recently become an invasive pest in Africa and in India. Having a detailed and standardized record of the biology and the larval development of S. frugiperda will be critical to further studies on integrated pest management, toxicology, and applied ecology. This study reports the temporal and morphological parameters of the immature stages of S. frugiperda for larvae fed on artificial diet under controlled conditions (25±1 °C, 70±10% RH and 14 hour photophase). The survival of the egg, larval, prepupal and pupal stages was 97.40, 98.33, 99.32 and 97.95%, respectively. The average duration of the egg, larval, prepupal and pupal stages were 2.69, 13.73, 1.43, and 9.24 days, respectively. All larvae passed through six instars, with significantly slower larval development for females. However, females had faster pupal development and heavier pupae, thus total time from egg to adult was not significantly different between sexes. With the growing importance of this highly polyphagous species, centralizing the fragmented information in the literature and standardizing its rearing methods will improve and facilitate future studies on this pest.

The interactions among insect communities influence the composition of pest complexes that attack crops and, in parallel, their natural enemies, which regulate their abundance. The lepidopteran stemborers have been the major maize pests in Kenya. Their population has been regulated by natural enemies, mostly parasitoids, some of which have been used for biological control. It is not known how a new exotic invasive species, such as the fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera, Noctuidae), may affect the abundance and parasitism of the resident stemborers. For this reason, pest and parasitism surveys have been conducted, before and after the FAW invaded Kenya, in maize fields in 40 localities across 6 agroecological zones (AEZs) during the maize-growing season, as well as at 3 different plant growth stages (pre-tasseling, reproductive, and senescence stages) in 2 elevations at mid-altitude, where all maize stemborer species used to occur together. Results indicated that the introduction of the FAW significantly correlated with the reduction of the abundance of the resident communities of maize stemborers and parasitoids in maize fields; moreover, the decrease of stemborer density after the arrival of FAW occurred mostly at both reproductive and senescent maize stages. It also suggests a possible displacement of stemborers by FAW elsewhere; for example, to other cereals. However, since this study was conducted only three years after the introduction of the FAW, further studies will need to be conducted to confirm such displacements.

AbstractThe fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), has become a major threat in maize cultivation since its invasion to India in 2018. The humpbacked fly, Megaselia scalaris (Loew) (Diptera: Phoridae), was recorded as a laboratory parasitoid of FAW, for the first time in India. Initially, 30–40 maggots of M. (M) scalaris emerged out from the dead pre-pupa and pupa of laboratory-reared FAW. The fly laid up to 15 eggs on the outer surface of 6th instar larva or pre-pupa of the FAW. The incubation period was 1–2 days. The fly had 3 larval instars which lasted 3–4 days and a pupal period of 10–11 days. The adults survived for 6–7 days.
