Do Boll Weevils Really Diapause? [PDF]
American Entomologist, 2010 Boll weevil, Anthonomus grandis grandis Boheman, diapause has been poorly understood since the term was first applied 50 yr ago to the pest's winter dormancy in temperate regions. In this literature-based study, I found that low temperatures and changes in photoperiod are the boll weevil diapause-induction factors most often referred to by scientists ...
