PLANTS, PEOPLE, PLANET, Volume 6, Issue 5, Page 1024-1037, September 2024.Agricultural extension is recognized as an important pathway for generating changes in individual farmers' practices and therefore broader patterns of production. In the United States, historical research has implicated extension work in transformations that privileged White farmers and wealthier operations over other producers and that fostered the ...

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.

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 ...

Do tissue carbon and nitrogen limit population growth of weevils introduced to control waterhyacinth at a site in the Sacramento-San Joaquin Delta, California? [PDF]
, 2004 Waterhyacinth (Eichhornia crassipes(Mart.) Solms), is a serious problem in the Sacramento Delta. Two weevil species (Neochetina bruchi Hustache and N. eichhorniae Warner) have been introduced as biological control agents. The purpose of this study was

Boll weevils in dry bolls: is there a performance disadvantage?
Journal of Cotton ResearchBackground Anthonomus grandis grandis is the main cotton pest in the Americas, with the potential to become a pest in other continents. The insect uses the plant’s reproductive organs for feeding, oviposition, and survival strategies in the off-season ...
