抄録

The toxicity of 29 fungicides was tested against 4 native phytoseiid species, namely, Amblyseius eharai Amitai and Swirski, Amblyseius tsugawai Ehara, Euseius sojaensis（Ehara）, and Typhlodromus vulgaris Ehara（Acari: Phytoseiidae）, which are abundantly found in fruit tree orchards in Japan. Mancozeb and propineb were toxic to the immature individuals of all 4 species and to the fecundity of adult females of E. sojaensis and A. eharai. Thiuram was harmless or slightly toxic to A. eharai, A. tsugawai, and T. vulgaris, whereas it was toxic to E. sojaensis. Sulphur and polyoxin were toxic to the immature individuals of all four species. Benomyl and thiophanate-methyl reduced the fecundity of A. eharai, A. tsugawai, and E. sojaensis. Fluazinam was toxic to immature individuals and the fecundity of adult females of E. sojaensis and moderately toxic to A. eharai and A. tsugawai. Iminoctadine triacetate was toxic to immature individuals of E. sojaensis. Fluoroimide was also moderately toxic to immature individuals of E. sojaensis. On the other hand, basic copper sulfate, oxine-copper, captan, chlorothalonil, iminoctadine tris（albesilate）, dithianon, difenoconazole, hexaconazole, imibenconazole, tebuconazole, fluopyram, inpyrfluxam, isopyrazam, penthiopyrad, pyraziflumid, cyprodinil, kresoxim-methyl, pyribencarb, and trifloxystrobin were harmless to all 4 species.
