Abstract
ABSTRACT Whitefly Bemisia tabaci (Genn.) populations were studied for five weeks on cantaloup (Cucumis melo L. cv. Annanas F1) to which different fertilizers (organic and inorganic) had been applied. The unfertilized control, ammonium sulphate at 100 kg N/ha, layer poultry manure (13.6 ton/ha, containing 3.9% N and 1.8% P) and broiler poultry manure (10.8 ton/ha, containing 5.0% N and 1.6% P) treatments resulted in a population of immatures of 21.0, 17.0, 7.0 and 6.0 per cm2 respectively, during five weeks. There were no significant differences in the populations between the control and the inorganic nitrogen treatments (P > 0.05), nor between the two types of poultry manure (P > 0.05). Populations were significantly lowered in the poultry manure treatments in comparison to the inorganic N and the control treatment (P < 0.05).
