MIGRATORY ECOLOGY OF THE BLACK CUTWORM
Annual Review of Entomology, 1997▪ Abstract The long-range migration of insects in general is briefly discussed here and serves as an introduction for in-depth inquiry into the migratory ecology of Agrotis ipsilon, the black cutworm. Zoogeography, pest status and injury, and seasonal occurrence of the species are reviewed. Circumstantial evidence of long-range movement of A.

A comparison of Paris green with sodium fluosilicate in poison baits against the greasy cutworm, Agrotis ypsilon , and the southern grassworm, Laphygma frugiperda , indicated that Paris green is more rapid in its action and considerably more toxic, and that A. ypsilon is more easily killed than L. frugiperda .

An Experiment in Trapping Cutworms
Journal of Economic Entomology, 19287703 cutworms were collected in traps at Waltham between April 27 and July 17, 1927. Chickweed sods were used as traps in the largest experiment where 6627 cutworms were collected but shallow trays with a screen bottom when baited with chickweed proved to be as effective and were more easily handled.

Insecticide and Acaricide Tests, 1990
Abstract Performance of granular and liquid insecticides against BCW was evaluated with artificial infestations at the Rosemount Experiment Station, Rosemount, MN. Treatment plots, each measuring 4 rows (30-inch spacing) × 50 ft, were established in corn planted on 2 Jun.

A nonoccluded virus of the army cutworm
Journal of Invertebrate Pathology, 1973Abstract A nonoccluded virus was isolated from larvae of the army cutworm, Euxoa auxiliaris. Infected larvae became lethargic and shrunken, and death usually occurred 12–20 days after infection. The primary site of viral infection and replication appeared to be the nuclei of midgut epithelial cells; however, virus replication also occurred in cells ...

Small-scale field trials using microplots were conducted to assess effectiveness of soil treatments of DDT, Dursban® ( O, O -diethyl 0-3,5,6-trichloro-2-pyridyl phosphorothioate), and Bayer 37289 ( O -ethyl O -2,4,5-trichlorophenyl ethylphosphonothioate) against larvae of the dark-sided cutworm, Euxoa messoria (Harris), attacking flue-cured tobacco ...

CUTWORM SYSTEMATICS: CONFUSIONS AND SOLUTIONS
Memoirs of the Entomological Society of Canada, 1993AbstractConfusion in cutworm systematics pervades every level of their classification ranging from problems in defining them as a monophyletic group to problems with defining species. Classification provides the primary means of communication and prediction and is most effective when names are stable, and the classification is widely accepted and used,

A pox virus of the army cutworm
Journal of Invertebrate Pathology, 1972Abstract A pox virus was isolated from a field-collected larva of the army cutworm, Euxoa auxiliaris . Death of diseased larvae usually occurred 16–18 days after infection when from 1 to 1.5 million polyhedral inclusion bodies per milligram of larval tissue were recovered.

Rearing the Army Cutworm on an Artificial Diet123
Journal of Economic Entomology, 1972Euxoa auxiliaries (Grote) was reared successfully on a semi synthetic diet for 10 generations without any apparent change in morphology, fecundity, or egg viability. Eggs hatched in 5 days when they were incubated at 26.5 and 80% RH. The 7 larval stages obtained with this rearing method were completed in 29-33 days, and 97% of the larvae survived.
