Evaluation of various natural diets for mass rearing of Spodoptera frugiperda J.E Smith (Lepidoptera: Noctuidae). Spodoptera frugiperda is one of the pests that attack corn in Indonesia. This study aimed to evaluate the most suitable diet for rearing of S. frugiperda from various natural diets. The study was conducted in vitro. The treatments were consisted of variation on S. frugiperda natural diets, such as maize leaf, green mustard leaf, water spinach, sweet potato leaf, sugar cane leaf, and soybeans leaf. The observed variables were life cycle period, pupa size, and pupa weight. The results showed that the shortest life cycle period was on corn leaves diet (40.92 days), and the longest was on sugarcane leaves (45.01 days). The longest size of pupa were S. frugiperda on mustard leaves diet (12.86 mm) and corn leaves (12.56 mm), The heaviest pupa weights were observed in S. frugiperda on mustard leaves diet (0.18 mg), and corn leaves (0.16 mg). Based on the data, it could be concluded that corn leaves were the most suitable type of diet for the growth and development of S. frugiperda.

The functional properties of marine invertebrate larvae represent the sum of the physiological activities of the individual, the interdependence among cells making up the whole, and the correct positioning of cells within the larval body. This chapter examines physiological aspects of nutrient acquisition, digestion, assimilation, and distribution within invertebrate larvae from an organismic and comparative perspective. Growth and development of larvae obviously require the acquisition of “food.” Yet the mechanisms where particulate or dissolved organic materials are converted into biomass and promote development of larvae differ and are variably known among groups. Differences in the physiology of the digestive system (secreted enzymes, gut transit time, and assimilation) within and among feeding larvae suggest the possibility of an underappreciated plasticity of digestive physiology. How the ingestion of seawater by and the existence of a circulatory system within larvae contribute to larval growth and development represent important topics for future research.

O objetivo deste trabalho foi avaliar o efeito da temperatura sobre a biologia dos biótipos "milho" e "arroz" de Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) e estimar o número de gerações por ano em laboratório e campo. Foram coletadas lagartas de quatro populações de S. frugiperda no Estado do Rio Grande do Sul, identificadas eletroforeticamente como os biótipos "milho" e "arroz", em áreas isoladas, distanciadas entre si em mais de 300 km, produtoras de milho e arroz irrigado e em áreas adjacentes, que produzem milho e arroz irrigado lado a lado. A temperatura mais adequada para o desenvolvimento dos dois biótipos foi 25ºC. Em laboratório, podem ser obtidas 11,0 e 11,3 gerações ano-1 do biótipo "milho" proveniente de áreas isoladas e adjacentes, respectivamente. Foram estimadas 12,1 gerações ano-1 do biótipo "arroz" quando proveniente de áreas isoladas e 12,2 gerações ano-1 quando proveniente de áreas adjacentes. Em campo, estimou-se a ocorrência de 8,3 e 6,1 gerações ano-1 do biótipo "milho", respectivamente, em áreas isoladas e áreas adjacentes e 8,4 e 7,0 gerações ano-1 do biótipo "arroz", respectivamente, em áreas isoladas e áreas adjacentes. Em áreas adjacentes, o biótipo "arroz" apresenta uma geração a mais ao longo de um ano em relação ao biótipo "milho".

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.
