Screening Dead Eggs of the West Indian Sweet Potato Weevil, Euscepes postfasciatus (Fairmaire) (Coleoptera: Curculionidae), by the Brine-flotation Technique.
In the artificial rearing of the West Indian sweet potato weevil, Euscepes postfasciatus, dead eggs should be screened before egg-seeding on an artificial diet because they could become sources ofExpand

Improvement of survival of the West Indian sweet potato weevil, Euscepes postfasciatus (Coleoptera: Curculionidae), by placing absorbent paper on the artificial diet after egg seeding and ensuring
A remarkable reduction of the post-hatching survival rate caused by adopting the furcellaran solution (a viscous liquid, hereafter FS) as an egg-seeding agent has become a problem during developmentExpand
