Sampling and dispersion of the twospotted spider mite (Acari: Tetranychidae) and the western orchard predatory mite (Acari: Phytoseiidae) on tart cherry
1990
Jones, V.P.
The distribution and dispersion of the Western orchard predatory mite, Typhlodromus occidentalis Nesbitt (Acari: Phytoseiidae) and its prey, the twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), were determined on tart cherry, Prunus cerasus L. Taylor's power law was used to quantify the relationship between mean and variance and develop binomial sampling plans. The association between Typhlodromus occidentalis and Tetranychus urticae was found to be statistically significant (P > 0.01), but weaker than that reported for Typhlodromus occidentalis and Tetranychus mcdanieli on apple in Washington.
