Abstract
A photographic sampling method for mites on plants was evaluated using Tetranychus urticae and Phytoseiulus persimilis on pepper plants. It was found to be 92% accurate for T. urticae eggs and 98% accurate for P. persimilis eggs at densities up to 45 eggs per cm2 for T. urticae, and up to 3 eggs per cm2 for P. persimilis. The motiles of the two species were not confused, nor were they confused with exuviae or other matter.
