Abstract
A complex of typhlodromid mites proved to be the most effective predators of tetranychid mites on citrus and avocado trees. Typhlodromus finlandicus, T. conspicuus, T. longipilus were collected from both citrus and avocado; T. sp. near finlandicus and T. similis were found on avocado but not on citrus trees. T. finlandicus was observed to feed on the citrus red mite Metatet-ranychus citri, citrus bud mite Aceria sheldoni and avocado brown mite Paratetranychus coiti, T. longipilus fed on avocado brown mite and 2 spotted mite Tetranychus bimaculatus T. sp. near finlandicus fed on avocado brown mite, citrus red mite, 2-spotted mite, 6-spotted mite Tetranychus sexmaculatus, and citrus bud mite. T. similis fed on avocado brown mite and 2-spotted mite. None of these predatory mites would feed on the pallid mite, Tydeus californicus T. conspicuus fed on T. californicus but would not feed on any of the tetranychid mites. None of these mites would feed on Brevipalpus mites. The food habits of 3 other spp. of mites, Typhlodromus masseii, T. pomi, and an undescribed spp. were studied.This publication has 0 references indexed in Scilit:
