Survey Recommendations
The following are recommendations for executing the survey using the approved methods for pest surveillance. The recommendations are developed through literature review and consultation with subject matter experts.
Key Diagnostic or Identification
Approved Method(s)
ID/Diagnostic:
Morphological: Dissection of genitalia may be required to differentiate between similar-looking native species.
Mistaken Identities:
Anarta trifolii (present in the United States) and Lacanobia w-latinum and Mythimna pallens (both not present in the United States) can be distinguished from M. brassicae by no tibial spur on foreleg. Apamea spp. can be distinguished from M. brassicae by no tibial spur on foreleg, and glabrous eyes. Mamestra configurata and Mamestra curialis are very morphologically similar to Mamestra brassicae, requiring dissection of male genitalia to distinguish between them. Mamestra configurata is present in the Western United States, and M. curialis is present in Canada and the northeastern United States.
