Abstract

Not available – first paragraph follows:

In sampling for spider mites on cotton, time limitations are important, especially when Tetranychus cinnabarinus (Boisduval) populations can reach levels exceeding tens of thousands per plant. Counting all Tetranychus spp. on a single cotton leaf often requires an hour or more. Consequently, few researchers or pest control advisors take the time for careful sampling.
