Abstract
To furnish parasites for release in 1942, overwintering corn borer larvae were collected in two localities, central Connecticut and southeastern Massachusetts, in the fall of 1941. Several of the most important parasites of the European corn borer imported from Europe and the Orient are established and abundant in these localities.
Collections were made in central Connecticut during the period October 27 to November 15, 1941. A total of 14,214 host larvae, or an average of 861 per working day, were obtained. Collections in southeastern Massachusetts were made during the period November 12 to 25 but, owing to a very light plant infestation, only 368 larvae were obtained per working day.
