“…Plant nitrogen fertilization effects on whiteflies and honeydew production under greenhouse conditions have been reported by several researchers (Blua & Toscano, 1994;Rubeiz et al, 1995;Bentz et al, 1995). Blua & Toscano (1994) indicated subtle differences in silverleaf whitefly development at different levels of cotton nitrogen fertilization.…”

“…On higher nitrogen treated plants, early-instar whiteflies initiated production of honeydew earlier than those on plants treated with medium or low nitrogen but subsequently generated fewer droplets (Blua & Toscano, 1994). Rubeiz et al (1995) reported that there were no significant differences in populations of the sweetpotato whitefly, B. tabaci (Gennadius), between the control and the nitrogen fertilized cantaloupes. However, Bentz et al (1995) found more B. tabaci on fertilized poinsettia plants than on nonfertilized controls.…”

The impact of nitrogen fertilization on cotton plants, Gossypium hirsutum L., silverleaf whitefly, Bemisia argentifolii Bellows & Perring, population dynamics and honeydew production were investigated in the field at Riverside, California, USA. Treatments were soil applications of 0, 112, 168 and 224 kg nitrogen per hectare, and a soil application of 112 kg of nitrogen plus a foliar application of 17 kg nitrogen per hectare. Increased numbers of both adult and immature whiteflies occurred during population peaks with increasing amounts of applied nitrogen. Higher numbers of whiteflies resulted in increased levels of honeydew. Increasing plant nitrogen also enhanced cotton foliar photosynthetic rates and stomatal conductance, and altered concentrations of glucose, fructose and sucrose in cotton petioles. However, at our treatment levels nitrogen had no effect on seedcotton yield. Petiole glucose levels were significantly correlated with numbers of whitefly adults on leaves during their peak populations. Significant correlations between whitefly numbers and other cotton physiological parameters occurred on only a few sampling dates.
