The boll weevil (Anthonomus grandis Boheman) preferred curved to flat-surfaced diets. On a cylindrically-shaped diet that was hemispheric at one end, the weevils fed and ovi- posited as well as on cotton buds. A mechanical method of removing eggs from diet involved breaking up the cylinders with water in a blender, placing the mixture in a sieve that retained the large particles but permitted the small particles and eggs to pass through, and floating the eggs in a sucrose solution to cause further separation. An effective oviposition diet consisted of enzymatic hydrolyzate of casein, sucrose, salts, cholesterol, B-vitamins, choline, inositol, ascorbic acid, germinated cottonseed, water, and agar. A similar diet with the addition of more ascorbic acid, corn oil, and fat-soluble vitamins was tried. During the first 20 days on these diets, each female laid an average of 114 and 202 eggs, respectively. Since tests were conducted over 12 months and conditions and weevils may have varied, the composition of the diet may not have caused the difference in oviposition. These crude diets are satisfactory for routine rearing.
