Changes in the Biology and Susceptibility of Weevil (Cylas formicarius) to the Insecticide Spinetoram as a Response to Cadmium Contamination [PDF]

Toxics
The sweet potato weevil Cylas formicarius is a notorious underground pest in sweet potato (Ipomoea batatas L.). However, little is known about the effects of cadmium (Cd) stress on weevil biology and resistance to pesticides and biotic agents. Therefore,

Defining the parameters of comet assay for reliably detecting DNA damage as a marker of X-ray based irradiation in insects treated with non-lethal doses for export fruit sanitation. [PDF]

Pest Manag Sci
Houseflies, clover root weevils, and mangoes were used to demonstrate the comet assay's adaptability. Our findings indicate that the comet assay can reliably detect irradiation‐induced DNA damage in both insects and fruit. However, the assay parameters require careful adjustment to account for differences in insect tissue types and life stages ...

Synthesis of (3Z)-Dodecenyl-(E)-2-butenoate, the Pheromone of Sweet Potato Weevil

Molecules, 1999
A practical synthesis of the title pheromone has been developed. The key feature of the synthesis was the fixation of the required olefin geometry via a cis-selective Wittig reaction and use of commercially available starting materials to prepare the ...
