Abstract:
The leaf turn method and the black pan method, two sampling methods for estimating the abundance of Bemisia tabaci (Strain B) on cotton, were compared over a two year period in Maricopa and Phoenix, AZ Both methods were highly correlated with the density of immature stages prior to the use of insecticides, but more poorly correlated after insecticide use began. The two methods were highly correlated with one another, however, leaf turn counts were better predictors of immature infestation. The leaf turn method was also much less variable between individual samplers than the black pan method. Finally, in terms of cost-efficiency it takes, on average, 71% less time to estimate population density with an acceptable precision using the leaf turn method. Based on these criteria, the leaf turn method is a more reliable and efficient technique for estimating adult abundance.
