Whitefly Population Growth in Cotton: A 3-Year Study in Maricopa, Arizona.

摘要

Populations of nymphs and adults of the sweetpotato whitefly, Bermisia tabaci Gennadius and the banded winged whitefly, Trialeurodes abutilonea Haldeman were observed on drip- or furrow-irrigated cotton, Gossypium spp. on the University of Arizona Maricopa Agricultural Center farm during the 1987-89 seasons. The relationships of whitefly populations to leaf water potential pH of leaf exudate, and soluble sugars in leaf sap of cotton plants were studied.
