Overwintering adult boll weevils were captured in pheromone traps in Brazos Co., TX, between February and May 1999. Collected boll weevils were starved for 50-58 hours, then allowed to feed freely for 24 hours on catkins or flowers of mossy-cup oak (Quercus macrocarpa A. Michaux), dandelion [Taraxacum laevigatum (C. von Willdenow) A. P. de Candolle], wine-cup [Callirhoë involucrata (T. Nuttall ex J. Torrey & A. Gray) A. Gray var. involucrata], Mexican palo verde (Parkinsonia aculeata C. Linnaeus), and cotton (Gossypium hirsutum C. Linnaeus). Boll weevils were sacrificed and the gut was removed and examined. A total of 699 boll weevils were examined for pollen. Pollen from all taxa tested was found in the guts of the boll weevils. Cotton pollen was found in the greatest and Mexican palo verde pollen in the least percentage of the boll weevils. Significantly more cotton pollen and significantly less Parkinsonia pollen was found in the samples than pollen from other taxa. There was no significant difference in the number of pollen grains between the sexes.
