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.

Chromosomal polymorphism in sweet potato weevil, Cylas formicarius.

CYTOLOGIA, 1985
Karyotype and sex-determining system of Cylas formicarius from Louisiana were determined as 10AA+XX in females, and 10AA+XY in most males with a few individuals exhibited both XY and Xyyp karyotypes. The culture from Hawaii had only Xyp males, those from Guam, Tinian and Taiwan were mostly Xyp although some were Xyyp and a few had both the Xyyp and Xyp
