Rapid estimation of numbers of whiteflies (Hemiptera : Aleurodidae) and thrips (Thysanoptera : Thripidae) on sticky traps
Australian Journal of Entomology 38 (4), 367-372
Abstract: The presence or absence of greenhouse whiteflies, Trialeurodes vaporariorum Westwood, and thrips, primarily western flower thrips, Frankliniella occidentalis (Pergande), in cells of a grid laid over 7.6 cm by 12.7 cm sticky traps was used to estimate the population density of these pests on the trap. The method accurately predicted trap population densities of between 15 and 192 individuals per side for thrips on blue and yellow traps and between 15 and 168 whiteflies per side on yellow traps. The distribution of both whiteflies and thrips tended to be clustered on the sides and upper edge of the traps. The method is useful in giving a far more rapid estimate than counting individuals, particularly at high population densities.
