Description

<p>We evaluated the effects of pesticides on two native generalist phytoseiid species, Amblyseius eharai Amitai and Swirski and Euseius sojaensis (Ehara), collected in and around citrus orchards in Shizuoka Prefecture Japan. Test results indicated that ethiprole, pyrifluquinazon, etoxazole, chlorfenapyr, flufenoxuron, lufenuron, buprofezin, flometoquin, spirodiclofen, spiromesifen, cyenopyrafen, cyflumetofen, pyflubumide, cyantraniliprole, flubendiamide, flonicamid, imibenconazole, boscalid, mepanipyrim, kresoxim-methyl, pyribencarb, cyazofamid, copper(II)-hydroxide, and dithianon do not have harmful effects on adult females of these species or their oviposition. Comparison of our findings with those of previous studies suggested that pesticide effects on generalist phytoseiids differ not only among species but also among populations. Therefore, to establish effective regional IPM programs, it will be necessary to further evaluate the effects of specific pesticides on generalist phytoseiid mite populations living in and around target orchards.</p>
