Research Article. Biological ... Agrotis ipsilon . The adult moths can be distinguished on the basis of wing shape and colour but this would require taxonomic expertise. Agrotis ipsilon Hufnagel Appearance and Life History. Traditionally, the management of maize pests has focused on cultural control and conventional insecticides. Agrotis ipsilon is one of the most widely distributed species of the cutworm complex. The black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae), is the most destructive pests against many economically important crops, including cotton. Integrated pest management (IPM) practices that consider both primary and secondary maize pests can complement IRM plans that are designed around primary pests. The following list will assist the reader with the acronyms for the insect pests discussed in this section. Black Cutworm (Agrotis ipsilon Hufnagel) Insect Fact Sheet integrated pest management Description Life Cycle Injury Black cutworm larvae vary in color from light gray to black and are about 1 ½ inches long when fully grown. It is generally considered to be worldwide in distribution. This management guideline is based on the assumption that for each 1% of plants with leaf feeding there is a good chance that 3 to 5% of the plants will eventually sustain damage due to cutting or notching. This project examined interactions between natural enemies of the black cutworm, Agrotis ipsilon (Hufnagel), an important turfgrass pest, and host plant resistance by endophytic grass. The frequent uses of chemical pesticides to protect field crops leads to the development of insecticide-resistant strains. While there are a few species that can be injurious in turfgrass of NY, the main species of concern are the black cutworm (BCW, Agrotis ipsilon) and the fall armyworm (FAW, Spodoptera frugiperda). This widely distributed pest is particularly a nuisance in Pakistan where it damages many crops, e.g., wheat and vegetables.
