Integrated pest control in gardens and amenities: a trial with Phytoseiidaea against spider mite on lime trees.

摘要

Experiments were conducted in Villandry, France in 2001, to study the efficiency of two Phytoseiidae species (Euseius finlandicus [Seiulus finlandicus] and Kampimodromus aberrans) on controlling the spider mite (Eotetranychus tiliarium) infesting lime trees (Tilia platyphyllos) of the park castle. Typhlodromus pyri, a mite successfully used in orchards, was also used. T. pyri settled down but their efficiency were not observed. During the year, Tetranychidae population stayed at relatively low level, except for the non-treated control. This may be due to climatic conditions in 2001, which was very humid, a factor that does not promote the Tetranychidae development. Except for the treated control, where Phytoseiidae were killed, Phytoseiidae were present at very high level.
