中文摘要:为科学评价触杀性粉剂对红火蚁Solenopsis invicta Buren的防治效果，利用0.2%高效氯氰菊酯粉剂对田间红火蚁蚁巢进行单蚁巢处理，分析粉剂施用剂量和次数对田间红火蚁种群数量及蚁巢迁移的影响。结果表明，触杀性粉剂处理可在短期内显著降低红火蚁的蚁巢数量和工蚁诱集数量，50 g/巢和100 g/巢处理1 d后，蚁巢数量降幅分别达55.17%和66.04%，工蚁诱集数量降幅分别达31.79%和51.95%，但5~9 d后基本恢复至处理前水平，第21天蚁巢增加率达86.21%和37.74%，持效性较差。增多粉剂施用次数同样也只能在短期内压低红火蚁的蚁巢数量和工蚁诱集数量，施用1、2和3次粉剂1 d后蚁巢数量降幅分别达61.44%、76.82%和80.79%，工蚁诱集数量降幅分别达55.40%、47.21%和28.36%，随着时间延长，蚁巢数量和工蚁数量很快恢复。虽然随着施药剂量增加，蚁巢增加率和分巢率明显降低，新蚁巢出现时间略有延迟，新蚁巢的体积明显减小，但整体来看蚁巢数量仍呈上升趋势，新蚁巢出现的距离和方位也没有明显差异。表明粉剂防治仅可在短期内表面上压低红火蚁种群数量，即使增加施药剂量和次数也不能有效降低红火蚁蚁巢数量，甚至会引起并加剧蚁巢的分巢扩散，建议在红火蚁防控中应慎重使用，或仅用于局部应急防控工作。

Abstract:In order to scientifically evaluate the effect of contact insecticide dusts in controlling the red imported fire ant, Solenopsis invicta Buren, individual mounds were treated with 0.2% beta-cypermethrin dusts in the field. Population density and colony relocation of S. invicta were studied by sprinkling different doses of contact insecticide dusts at different frequencies. The results showed that treatment with 50 g/mound and 100 g/mound contact insecticide dusts significantly reduced the density of active mounds of S. invicta by 55.17% and 66.04%, and decreased the density of baited workers of S. invicta by 31.79% and 51.95% one day later, respectively. The population density of S. invicta returned to the normal level during five to nine days later with a poor sustainability. At 21st day, the increasing rate of mounds of S. invicta reached 86.21% and 37.74%, respectively. Similarly, application of contact insecticide dusts for one to three times also reduced the density of active mounds of S. invicta by 61.44%, 76.82% and 80.79%, and decreased the density of baited workers of S. invicta by 55.40%, 47.21% and 28.36% one day later, respectively. The population density of active mounds and baited workers of S. invicta recovered quickly with time. Although the rate of mound growth and division significantly decreased with increasing doses of contact insecticide dusts, and the appearance time of new mounds was slightly delayed, and the size of new mounds significantly decreased, no significant differences were observed between the movement distance and orientation of new mounds. Overall, the density of mounds showed an upward trend, indicating that contact insecticide dusts could only reduce the population density of S. invicta temporarily. Even increasing the application dosage and frequency of contact insecticide dusts could not effectively reduce the number of fire ant mounds. Contact insecticide dusts even worsened the budding and diffusion of fire ant colonies. Caution should be taken in using contact insecticide dusts for controlling the red imported fire ant, and it is recommended only for emergency control.
