Mineral Content of Boll Weevils, Cotton Buds, and Synthetic Diets

The mineral content of Anthonomus grandis</it> Boheman, wild and mass-reared, cotton buds, and synthetic diets was determined by atomic absorption spectrophotometry. Manganese was low by a factor of 10 in the artificial diet when compared to cotton squares. All minerals except copper were enhanced, especially iron (100-fold) in overwintered weevils when compared to F<inf>1</inf> weevils.
