Abstract:

Laboratory studies were conducted to determine the effects of various food sources and temperature on adult longevity of the boll weevil,Anthonomus grandis Boheman. Boll weevil adults reared from cotton have the potential to live up to 9 mo on a continuous supply of cotton flower buds (squares). Kenaf, Hibiscus cannabinus L., and okra, H. esculentus L., flower buds playa minor role in boll weevil survival, but hibiscus, Hibiscus rosasinensis L., could be important for survival because weevils can exist for up to 4 mo on this food source. Boll weevil longevity was increased on all food sources at temperatures of 18 and 24"C compared with longevity at 12 and 3O"C. Use of alternative feeding sources could aid boll weevil survival during periods when cotton fruiting structures are not available.
