Abstract
A simple and inexpensive technique for measuring ingestion by adult Anthonomus grandis Boheman is described. Identical results were obtained using both the chromic oxide method and a red dye (Calco Oil Red N-1700®). Recovery of dye injected into adult weevils averaged 98%. No evidence of metabolism of the dye for as long as 8 hr postinjection was observed. The dye has no deleterious effects on the boll weevil, is easily recovered, and docs not require the use of dangerous chemicals prepared reagents, or a chemical reaction. Suggestions are made for formulating the dye to obtain uniform dispersions in aqueous media.
