Abstract:

A high per cent carryover of boll weevils (Anthonomus grandis Boheman) from one crop year to the next occurs in surface ground trash in wooded areas adjacent to infested cotton fields. In central Texas recent studies have indicated that boll weevils can survive from one crop year to the next in bolls on standing stalks within cotton fields. Boll weevils can also over winter in bolls on the soil surface, even during winters of more than usual weather severity. When bolls were buried to a depth of 2 in. on December 1, results indicated that survival can occur within fields even though stalks were destroyed and fields plowed in early winter. However, survival was considerably less than in bolls remaining on the soil surface throughout the winter. Such survival could be important in areas where favorable hibernation sites are scarce or nonexistent.
