ABSTRACT
Sticky cotton caused by insect honeydew contamination is a major issue in the cotton industry. Bemisia tabaci (Gennadius) Strain B (= B. argentifolii Bellows and Perring) honeydew contributes to cotton lint stickiness. Increases in thermodetector sticky cotton counts and trehalulose and melezitose were correlated to increasing Bemisia nymph and adult populations. Effective chemical control reduced whitefly populations and sticky cotton levels. Thermodetector counts did not reach levels  5 until average Bemisia adult leaf-turn counts were 11.7 or nymphs were 1.7 per cm2 of leaf disk during the open mature cotton boll period.
