Within-plant distribution of Bemisia tabaci (Homoptera: Aleyrodidae) adults and immatures on greenhouse-grown winter cucumber plants
Journal of Economic Entomology 100 (4), 1160-1165
Abstract: Within-plant distribution of adults, pupae, nymphs, and eggs of Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) on leaves of greenhouse-grown winter cucumber, Cucumis sativum L., plants were studied in field plots for integrated pest management decision making. Distribution of specific life stages depended on the leaf positions. The leaves with most abundance and low or lowest variation of whiteflies were leaves 8-12 for adults, 8-11 for pupae, 6-12 for nymphs, and 6-9 for eggs. In light of the criterion in selecting within-plant sample sites with pest abundance and low variation, these leaves were considered as the most convenient for sampling specific life stages of B. tabaci. Single a and b values for each life stage of the whitefly were calculated by Taylor's power law and were used to estimate minimum sample sizes at a precision of 0.25 (SE/mean). The minimum sample size decreased with increasing density of adults on leaves 8-12, of nymphs on leaves 7 and 8, and of eggs on leaf 6, but slightly increased with increasing density of pupae on leaves 8-11, of nymphs on leaves 6 and 9-12, and of eggs on leaves 7-9.
