Interpretive Summary: PBW moths have been reported to live longer and females produce more viable eggs when provided a source of adult food (sugar or honey solutions). Moths have been assumed to feed on cotton plant nectaries and indeed larval infestations in cotton bolls are drastically reduced in nectariless cotton fields. Cottons containing the gene from Bacillus thuringiensis var. Kurstaki (Berliner) controlling the production of insect toxic protein (Cry1Ac) (Bt cottons) have been grown commercially in Arizona since 1996. The results have been outstanding. PBW larval infestations in green cotton bolls have been < 0.5% annually.
