【摘要】 使用溴甲烷对 1 6种切花及主要携带的南美斑潜蝇、棉蚜、二斑叶螨及花蓟马等害虫进行熏蒸试验。结果表明 :如仅带有蚜虫或蓟马 ,所有供试切花均可进行熏蒸处理 ;如带有叶螨或斑潜蝇 ,金鱼草、菊花和孔雀草不宜熏蒸 ,玫瑰、勿忘我、康乃馨、百合、马蹄莲、情人草、非洲菊、剑兰和石斛兰可以熏蒸 ,满天星、天堂鸟、橙菠萝和紫罗兰在 2 1℃下以 3 6g/m3,1 5h处理 ,对品质有轻度影响 ,但可 1 0 0 %杀死叶螨及斑潜蝇的成虫、幼虫和蛹。由于斑潜蝇卵的耐药性比其它虫态要强 ,对带有斑潜蝇卵而耐药性较差的切花 ,可以在采收后于室温下放置 1～ 3天 ,待卵孵化后再进行熏蒸处理。更多还原

【Abstract】 Using methyl bromide (MB) to fumigate 16 cutflowers and their pest insects,Liriomyza huidobrensis Blanchard,Aphis gossypii Glover,Tetranychus urticae Koch and Frankliniella intonsa Trybom in this test,the results showed that:anyone of the 16 flowers with only aphids like Aphis gossypii or thrips like Frankliniella intonsa can be fumigated,If there are mites like Tetranychus urticae or serpentine leafminer like Liriomyza huidobrensis,snapdragon,chrysanthemum of aster hybriden is not suitable for fumigation,rose,limonium sinuatum,carnation,lily,calla,limonium,gerbera,gladiolus or dendrobium is suitable for fumigation.Using MB in the dosage of 36 g/m 3for 1 5h under 21℃can kill all of the mites or the adults,larvae and pupae of the leafminer,but it can make slight side effects to the quality of gypsophila,strelitzia reginae,carthamus tinctorius or matthiola incana.Because the endurance of eggs of the leafminer to MB is higher than the adults,larvae and pupae,those cutflowers with lower endurance to MB can be placed indoor for 1～3 days after harvesting,then eggs of the leafminer are hatchcd and the cutflowers can be fumigated.更多还原
