Overview

Excerpt from Fruit Notes of New England, Vol. 64 How can T. Pyri be used to provide cost-free mite control? Achieving biological mite control using T. Pyri is minimally a one-step process and may require two steps. First, an environment must be established in the orchard that will allow T. Pyri to survive and flourish. This requires that pesticides that are toxic to these beneficial mites not be used. Second, if T. Pyri are not already present in the orchard, they must be introduced. An environment conducive to T. Ei T. Pyri have acquired resistance to some chemical pesticides used in commercial orchards and are innately tolerant of others. However, some pesticides are quite toxic to T. Pyri. If biological mite control is to be achieved using this predator, these toxic materials must be avoided. Because T. Pyri are resident in trees year round, and because these predators have a relatively slow growth rate, pesticides toxic to T. Pyri cannot be used even intermittently every other year) without serious disruption to biological control. A list of pesticides that can be used to control insects and diseases of apple while conserving T. Pyri is provided in Table 2. Be advised that estimates of toxicity to T. Pyri were obtained using predators from western ny, and there may be differences in susceptibility among predator populations indig enons to other regions of the Northeast.
