Abstract:Compound eyes of boll weevils, Anthonomus grandis grandis Boheman, reared for many generations on artificial diets at the Gast Rearing Laboratory had reduced visual sensitivity when compared with field-collected weevils. Visual sensitivity was measured using electroretinographic methods. Vision of both recently colonized boll weevils (<1 year) reared on the standard larval diet without the calico red dye marker, and boll weevils of the Gast strain reared on the same diet with and without calico red dye, was impaired greatly. Laboratory-reared boll weevils were 400-fold less sensitive to monochromatic light stimuli at 510 nm than held-collected weevils. Visual sensitivity of recently colonized weevils and the Gast laboratory-reared weevils (reared on diets with and without calico red dye) improved to approximately one-half that of field-collected weevils after feeding on cotton seedlings for 4–5 days.
