In the present study, we identified a novel, positive-sense single-stranded RNA virus in the Chinese black cutworm, Agrotis ipsilon. It has a genome length of 11,312 nucleotides, excluding the poly(A) tails, and contains five open reading frames. The ORF2 encodes the conserved domains of RNA helicase and RNA-dependent RNA polymerase, while ORF4 and 5 encode three viral proteins. Herein, the A. ipsilon virus was clustered with a Helicoverpa armigera Nora virus and was thus provisionally named “Agrotis ipsilon Nora virus” (AINV). AINV was successfully transmitted into a novel host, Spodoptera frugiperda, through injection, causing a stable infection. This found the possibility of horizontal AINV transmission among moths belonging to the same taxonomic family. Nonetheless, AINV infection was deleterious to S. frugiperda and mainly mediated by antiviral and amino acid metabolism-related pathways. Furthermore, the infection significantly increased the S. frugiperda larval period but significantly reduced its moth eclosion rate. It suggests that AINV is probably to be a parasitic virus of S. frugiperda.

Diapetimorpha introita (Cresson) occurred from May to November and was the primary parasitoid of fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith), pupae in corn fields at Tifton, GA, from 1983 to 1985. Another previously unreported pupal parasitoid of FAW, Cryptus albitarsis (Cresson), occurred only during a single sample conducted in November 1984. Rates of parasitism averaged 5.2% (range 0–23.7%) and 8.4% (range 0–50.0%), respectively, during 1983 and 1984, with the highest rate occurring in September to November of each year. In a limited study conducted in September and October 1985, total pupal parasitism averaged 33.3% (range 0–44.4%). Predation was the primary mortality factor, averaging 44.7, 37.8, and 95.8%, respectively, during 1983, 1984, and 1985. Predators found either in FAW pupation tunnels or feeding directly upon pupae were earwigs, Labidura riparia (Pallas); nonidentified carabid beetles; wireworms, Conoderus sp.; and the imported fire ant, Solenopsis invicta Buren. These studies indicate parasitoids and predators of FAW pupae play a primary role in regulating FAW populations following their development in corn and likely significantly reduce the numbers that subsequently disperse into new habitats for oviposition on other crops.
