The quiescent physiological status of boll weevils (Coleoptera: curculionidae) during the noncotton season in the tropical zone of Soconusco in Chiapas, México

Studies with tropical Anthonomus grandis grandis Boheman from southern Mexico indicated that these weevils remained quiescent, did not attain a true diapause state, and remained potentially physiologically active and reproductive during the noncotton season (January-July). The weevils completed their life cycles and remained encapsulated in a "quiescent" or "resting" state inside the dry bolls throughout the dry season (January-March). Over 50% of the dry bolls that were collected in January and February and protected from the rain yielded live reproductive weevils when opened in July. The sexual organs ranged from medium to large, and abdominal lipid content ranged from moderate to great, for male and female weevils dissected between January and July. All weevils were found to be active and capable of reproduction a few hours after eclosion from the dry bolls.
