Pollination biology of Gossypium turneri: Autonomous selfing provides reproductive assurance in an endangered wild cotton from Sonora, Mexico

Plant Species Biology, Volume 39, Issue 5, Page 260-274, September 2024.
Gossypium turneri is a wild cotton that is currently threatened by tourism development and an invasive species. Our results indicate that this species has the ability of autonomous self‐pollination by style curvature, providing reproductive assurance when pollinators are scarce. This finding is relevant as current disturbance might disrupt interactions

Assessing the sterility and quality of gamma‐irradiated pepper weevils, Anthonomus eugenii (Coleoptera: Curculionidae), toward the development of the sterile insect technique

Pest Management Science, Volume 80, Issue 4, Page 1692-1701, April 2024.
Pepper weevil were treated with gamma radiation at the pupal stage to investigate its impact on reproduction and quality. Male and female pepper weevils irradiated with 110 Gy as late‐stage pupae were effectively sterilized and also had decreased fecundity, longevity and spontaneous flight activity.

Fungal seed treatments of cotton affect boll weevil development

Pest Management Science, Volume 80, Issue 3, Page 1566-1576, March 2024.
Fewer boll weevil larvae hatched and fewer adults emerged from fungal‐treated plants. In addition, the developmental time from oviposition to adult emergence was delayed in the fungal‐treated plants. Abstract BACKGROUND Nonpathogenic fungi associated with plants can enhance plant defenses against stress factors, including herbivory. This study assessed

Starvation-Induced Morphological Responses of the Boll Weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae)

Journal of Cotton Science, 2017
Status of the boll weevil, Anthonomus grandis grandis Boheman, as a pest of cotton (Gossypium spp.) in the United States has diminished because of progress by eradication programs. However, this pest remains of critical importance in South America, and intractable populations in extreme South Texas and northern Mexico persistently threaten ...
