| Research Abstract |
To investigate a possible model in which native natural enemy is artificially introduced into the agricultural land and it is used as a biological control agent, the study was conducted using spider mites and predacious phytoseiid mites system. The main target was set on a predacious mite species (A.finlandicus (Oudemans)) living on Magnolia hypoleuca, which was introduced in apple orchards to control spider mites. Experimental application was conducted at Morioka in 2003-2004, but clear results was not obtained due partially to low spider mite density during the experimental period.
During the course of the study, species composition of phytoseiid mites on Magnolia hypoleuca was clarified in northern and middle-to-south Japan. In north, A. Gnlandicus (Oudemans) was a dominant species but in south of Mie and Gifu prefectures A.sojaensis Ehara replaced the position.
These results were presented at international conferences such as ICA (Sept.2002,in Mexico) and EURAAC (July 2004,in Berlin) and others.
