Adults of the boll weevil naturally exhibit considerable variation in size. Yet the reproductive consequences of this variability have not been examined. We examined the relationships between pupal weight of the female boll weevil and subsequent feeding and reproductive activities. Numbers of egg punctures, numbers of feeding punctures, and the ratio of egg punctures to total punctures were reduced in females weighing < 10 mg.

Species 1: Coleoptera Curculionidae Anthonomus grandis grandis (boll weevil)
Keywords: punctures, variation
