摘要

從玫瑰及蓎菖蒲上採回含有神澤氏葉蟎的葉片，選常用之殺蟎劑，以噴霧法處理葉片。試驗結果，玫瑰上神澤氏葉蟎在供試14種殺蟎劑中，殺蟎率達91.2%以上的藥劑有25%蟎離丹（Oxythioquinox）可濕性粉劑500倍、2.8%畢芬寧（Bifenthrin）乳劑2,000倍、25%新殺蟎（Bromopropylate）乳劑500倍、20%西脫蟎（Benzomate）乳劑1,500倍及57%歐蟎多（Propargite）乳劑2,000倍等5種藥劑。次為20%三亞蟎（Amitraz）乳劑800倍、80%硫黃（Sulfur）水分散性粒劑500倍、50%芬佈賜（Fenbutatin-oxide）可濕性粉劑2,000倍，其殺蟎率在83.4～89.6%之間。但對神澤氏葉蟎的卵僅20%西脫蟎（Benzomate）乳劑1,500倍及50%芬佈賜（Fenbutatin-oxide）可濕性粉劑2,000倍及50% Polo可濕性粉劑1,500倍較有效，其殺卵率在83.8～92.5%之間；對蓎菖蒲上之神澤氏葉蟎成、若蟎之殺蟎效果，在8種供試藥劑中以25%蟎離丹（Oxythioquinox）可濕性粉劑500倍、2.8%畢芬寧（Bifenthrin）乳劑1,000倍、57%歐蟎多（Propargite）乳劑1,000倍及25%新殺蟎（Bromopropylate）乳劑500倍等4種較優，其殺蟎率在93.5～99.2%之間，效果甚佳，對卵亦以上述藥劑較佳，唯殺卵率略有下降。從試驗結果顯示，多種殺蟎劑同時對玫瑰及蓎菖蒲上之神澤氏葉蟎均有佳效，若能正式推荐，足供花農輪流使用。

Several common miticides were sprayed onto leaves to test their effectiveness against the kanzawa spider mites collected from roses and gladiolus. Five of the 14 miticides tested, i.e., 25% Oxythioquinox W. P. (500-fold), 2.8% Bifenthrin E. C. (2000-fold), 25% Bromopropylate E. C. (500-fold), 20% Bnzomate E. C. (1500-fold) and 57% Propargite E.C. (2000-fold) produced mortality as high as 91.2% of this spider mite of roses. 20% Amitraz E. C. (800-fold), 80% Sulfur F. G. (500-fold), 50% Fenbutatin-oxide W. P. (2000-fold), and 50% Polo W. P. (1500-fold) also produced 83.4% to 89.6% mortality. However, only 20% Benzomate E. C. (1500-fold), 50% Fenbutatin-oxide W. P. (2000-fold) and 50% Polo W. P. (1500-fold) were ovicidal and gave 83.8% to 92.5% mortality. Among the 8 miticides tested, 25% Oxythioquinox W. P. (500-fold), 2.8% Bifenthrin E. C. (1000-fold), 57% Propargite E. C. (1000-fold) and 25% Bromopropylate E. C. (500-fold) gave excellent control (93.5% to 99.2%) of nymphs and adults of Kanzawa spider mites collected from gladiolus. These chemicals also showed good, but somewhat lower, ovicidal activity. These results indicate that many miticides are still effective against Kanzawa spider mites on roses and gladiolus, and if officially recommended, they can be used alternately by the growers.
