The bertha armyworm, Mamestra configurata Walker (Lepidoptera: Noctuidae), causes periodic but severe damage to canola crops in North America, particularly in the Canadian provinces of Alberta, Saskatchewan and Manitoba. These web pages provide information on the tachinid flies (Diptera: Tachinidae) recorded from bertha armyworm in North America. A key to adults is provided for separation of the genera, and each species known from bertha armyworm is characterized with respect to recognition, biology (including hosts) and distribution. The species included are listed under Insect Parasitoids of Bertha Armyworm.
These web pages on the tachinids of bertha armyworm are adapted from the following paper:
