Abstract

The behaviour of individual adult female European red mites was observed on peach leaf discs sprayed with different numbers of 200 micron droplets of nigrosine dye solution, nigrosine plus Carzol miticide, and nigrosine plus dicofol. On nigrosine and Carzol deposits, the relationship between the number of contacts and the number of stains was linear, but the addition of Carzol reduced the slope of the line. Tests of stains containing dicofol were intermediate to those of nigrosine and Carzol.
