| Abstract: | Fifteen cotton cultivars were evaluated in Israel during 1985 or 1986 for resistance to sweetpotato whitefly, Bemisia tabaci (Gennadius). Lowest whitefly populations were found on the okra-leaf cottons; however, lower yields were obtained with the most resistant okra-leaf type cotton tested. Under dryland cotton culture, whitefly populations were higher than under auxiliary or normal irrigations. High whitefly populations were positively correlated with high reducing and total sugar contamination of the cotton lint. |
