Abstract

Campylomma verbasci (Meyer) overwinters as an egg on apple, pear, Rosa spp., and Amelanchier sp. On pear, the chief prey are eggs and nymphs of Psylla pyricola Forster and all stages of Panonychus ulmi (Koch). C. verbasci is partially phytophagous but prolonged feeding by nymphs on pear fruits caused no injury. During the summer, C. verbasci lives and reproduces as a predator–phytophage on a number of herbaceous plants. Three, possibly four, generations occur in the southern interior of British Columbia. The effects on C. verbasci populations of a number of pesticides applied to pear trees are reported.
