Abstract:Tetranychus urticae Koch usually appears on peach trees. Prunus persica L.. ca. 2 mo before harvest in South Australia. DIfferent densities of mites per leaf were induced by applications of carbaryl so that the effect of mite density on yield could be investigated. Yields were not affected by up to 40–50 mites/leaf, but higher numbers affected yield in the final growth phase of the fruit. The results agree with physiological evidence which suggests that photosynthetic area in peach trees is rarely rate-limiting, and that a healthy peach tree can compensate for moderate mite feeding.
