Beneficial insects; Insect pests. - 34 - Boll Weevil Hibernation Survey In Louisiana - Fall 1964 The fall collections of surface woods trash (two square yards per sample) were made in Madison, East Carroll and Tensas Parishes (northeast area) from November 23 to December 3, 1964, to determine the number of boll weevil (Anthonomus grandls) adults that went into hibernation. A total of 3 samples was collected at each location, with 10 locations in East Carroll, 10 locations in Tensas and 20 locations in Madison Parishes being used. A total of 120 samples was collected at these 40 locations. The average number of live boll weevils per acre in the tri-parish area was 5,875. This compares with an average of 7,317 in the fall of 1963. The average by parish was 4,154 in Madison, 9,842 in East Carroll and 3,630 in Tensas. During the 10 past falls that these records have been made in the tri-parish area, the number of weevils per acre has ranged 2,622 to 13,443 and averaged 5,855 in Madison Parish; 5,165 to 13,235 and averaged 8,868 in East Carroll Parish; and 0 to 17,593 and averaged 6,702 in Tensas Parish. During the past 29 years that similar records have been made in Madison Parish, there have been 10 years in which a larger number of weevils has been found in ground trash in the fall than the 4,154 found in Average number of boll weevils per acre of ground trash A light frost occurred the second and third weeks of October, and a low of 31 degrees was recorded October 20; however, cotton was not completely killed until November 22 and 23 when a low of 25 degrees was recorded on these 2 dates. Cotton stalks had been destroyed on only about 25 percent of fields near woods trash sampling areas. Trash collected was ideal in most cases for running through separatory screens. Collections were interrupted twice by rain, once on November 24 and once on November 27. (T. C. Cleveland). Boll Weevil Hibernation Survev in Tennessee — Fal
