A greenhouse procedure was developed for maintaining a culture of Trialeurodes abutilonea (Haldeman) on cotton, Gossypium hirsutum L. One U.S. and 35 foreign cotton cultivars were evaluated for relative levels of resistance or susceptibility to bandedwinged whitefly colonization and emergence of adults. When compared with the commercial cultivar ‘Deltapine 16’ (DPL-16), one foreign cotton, ‘C-1211,’ had significantly (P = 0.05) lower levels of whitefly colonization. Six foreign cultivars, ‘Lasani 11,’ ‘M4 (N.T. Sind),’ ‘4S 180,’ ‘CX 349,’ ‘138-F,’ and ‘108-F,’ had levels of colonization that were not significantly different from DPL-16. None of the cultivars had significantly less adult emergence than DPL-16, and 17 had adult emergence levels that were not significantly different.
Weights were determined for tobacco budworm, Heliothis virescens F., larvae grown from hatching to 5 days of age on excised terminal leaves from a selected set of 35 foreign and eight 8 USA cotton, Gossypium hirsutum L., cultivars and strains. These data supplement previously published information from our laboratory for these cultivars and strains on resistance to three other insect pests and on agronomic, fiber property, morphological, and disease resistance measurements from Oklahoma. Larvae reared on ‘BJA 592’, ‘Laxmi’, ‘SATU 65’, MO‐HG, and HG‐BR‐8‐N were significantly (P = 0.5) smaller than those on ‘Deltapine 16’. Larvae reared on Laxmi were also significantly smaller than those on ‘Stoneville 213’.
