Abstract
Overwintering rice water weevils, Lissorhoptrus oryzophilus Kuschel, were held at different temperatures with and without food to determine the response of indirect flight muscle regeneration. Flight muscle regeneration has a temperature threshold of ca. 18°C. The rate of regeneration is greater at higher temperatures and when adults feed. Emergence of adult weevils from overwintering sites was monitored with sticky traps for 4 years near Stuttgart, Ark., and for 2 years near Crowley, La. The date adults emerged in the spring is closely related to springtime temperatures.Keywords
