An entomopathogenic nematode, Steinernema carpocapsae (Weiser) All strain (BioVector®), applied at two rates (1.25 and 2.5 × 109 nematodes/ha) was compared with several registered insecticides for controlling black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae), larvae during the 1991 growing season in Illinois. Fonofos, tefluthrin and chlorpyrifos were applied at planting time; permethrin and the two rates of nematodes were applied as postemergence rescue treatments. The nematodes generally performed as well as or better than the conventional insecticides in controlling black cutworm larval injury to seedling corn. Bioassays with black cutworm larvae showed that nematode efficacy was lost 8 days after application in the field. Entomopathogenic nematodes hold promise for controlling black cutworms in corn, particularly for corn grown under irrigation.

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.
