摘要
红火蚁是元谋干热河谷区一种具有重大危害的危险性入侵生物,为了筛选出适用于干热河谷区的红火蚁防治药剂,开展了 7 种杀虫剂对红火蚁的防效试验.结果表明:对蚁巢的防控效果,药后 7 d以 8%高效氯氰菊酯可湿性粉剂的最好,其次是 0.73%氟蚁腙饵剂,平均防效分别为 100.00%和 93.75%,药后 14 和 21 d时,8%高效氯氰菊酯可湿性粉剂和 2.05%氟蚁腙吡虫啉杀虫饵剂的防效均达 100.00%,其他药剂处理的防效均为 93.75%;8%高效氯氰菊酯可湿性粉剂在施药后 1 d时单个蚁巢工蚁的虫口减退率达 100.00%,且显著高于除0.1%呋虫胺饵剂处理以外的其他处理,施药后7 d供试药剂的虫口减退率均在 90%以上,但在施药后 21 d时其虫口减退率均出现下降.因此,可交替使用7 种供试药剂进行红火蚁的防控,建议先撒施 0.2%高效氯氰菊酯粉剂、0.73%氟蚁腙饵剂、2.05%氟蚁腙吡虫啉杀虫饵剂等控制红火蚁,然后用 8%高效氯氰菊酯可湿性粉剂灌巢彻底铲除红火蚁.
Abstract
The red imported fire ants are dangerous invasive pests in Yuanmou dry-hot valley area.A field experiment was conducted to determine the control effects of 7 insecticides against red imported fire ants,on the basis of which the insecticides suitable to be applied here were screened out.The results showed that on day 7 after application,8%cypermethrin wettable powder had the strongest control effect on the nests of red imported fire ants,followed by 0.73%hydramethylnon bait,which showed the mean control effects of 100%and 93.75%,respectively.On days 14 and 21 after application,8%cypermethrin wettable powder and 2.05%hydramethylnon + imidacloprid bait showed the control effect of 100%,and other insecticides showed the control effect of 93.75%.On day 1 after application,8%cypermethrin wettable powder reduced the ants per nest by 100%,which was higher than that of other treatments except 0.1%dinotefuran bait.On day 7 after application,8%cypermethrin wettable powder reduced the ants per nest by over 90%,which,however,decreased on day 21.The seven insecticides tested can be used alternately according to the environmental changes in Yuanmou dry-hot valley area for effective control of red imported fire ants.Specifically,0.2%cypermethrin powder,0.73%hydramethylnon bait,2.05%hydramethylnon + imidacloprid bait and other insecticides can be used to control the population,and then 8%cypermethrin wettable powder can be used to eradicate red imported fire ants.
