Abstract
ABSTRACT EQUIPMENT and techniques have been improved for mechanizing the Boll Weevil Larval Rearing System. The equipment is designed to form rearing trays from plastic film, fill the trays with food, rapidly cool the food, place eggs on the food, cover the eggs with a granular material, heat-seal a cover on the tray, and shear trays as desired. Trays for rearing weevils are processed at a rate that will provide slightly more than 106 weevils/h. A method of rearing weevils without using granular materials produced 85 percent as many weevils as were produced when using the granular materials. Also, an alternate tray cover was tested, with satisfactory results, and costs one-third as much as the cover previously used.
