Some Shortcuts in Laboratory Rearing of Boll Weevils1

Abstract

A method of reducing the time required for laboratory rearing of the boll weevil, Anthonomus grandis, is presented. Egg extraction from cotton squares is accomplished by grinding squares in a blender and separating eggs by means of screens and salt flotation. A description is given of simple mechanical rollers for removing the leaf bracts from the squares prior to placing them in the oviposition cage.
