【摘要】：目的观察中华按蚊吸血趋性和吸血前后活动情况,为改进灭蚊措施,提高防制效果提供依据。方法利用室外人、牛饵帐诱捕法进行中华按蚊吸血趋性观察,采用实验小屋法观察蚊虫吸血前后活动情况。结果室内人饵帐捕获中华按蚊约是室外捕蚊数的2.99倍,差异有统计学意义(χ2=15.12,P0.01);室内外牛饵帐诱捕蚊数相近,差异无统计学意义(χ2=0.69,P0.05)。牛房傍晚3h的捕蚊数为白天栖息该室内蚊虫数的12.59倍,在室内吸血前后停息1~10min者约占50%,停息30min以内者占80%以上,差异均有统计学意义(P0.05);停息60min以上者仅占10%,差异无统计学意义(P0.05)。结论中华按蚊具有偏外栖性,这是滞留喷洒杀灭效果不理想的重要原因。基于其吸血前后室内短暂停留的行为习性,应选用无驱避性且具有熏杀作用的速效高效杀虫剂杀灭室内中华按蚊。
[Abstract]:Objective to observe the tendency and activity of Anopheles sinensis before and after blood sucking so as to provide evidence for improving mosquito control measures and control effects. Methods the blood absorption tendency of Anopheles sinensis was observed by the method of outdoor human and cattle bait trapping, and the activity of mosquitoes before and after blood sucking was observed by the method of laboratory cabin. Results the number of Anopheles sinensis captured by indoor human bait was 2.99 times of that of outdoor ones (蠂 ~ 2 ~ 2 ~ (15.12) P _ (0.01), but the number of mosquito trapping by cattle bait was similar (蠂 ~ (2) 0.69) (蠂 ~ (2) 0.69 (P _ (0.05). The number of mosquitoes caught at 3 hours in the evening of cattle house was 12.59 times of that in the daytime. The number of 1~10min stopped before and after indoor blood sucking was about 50, the rest of 30min was more than 80%, the difference was statistically significant (P0.05), and the rest of 60min accounted for only 10%, the difference was not statistically significant (P0.05). Conclusion Anopheles sinensis has extraneous nature, which is an important reason for the unsatisfactory efficacy of residual spraying. Based on the behavior of temporary stay in the room before and after bloodsucking, it was suggested that the effective and effective insecticides with no repellent and fumigation effect should be used to kill Anopheles sinensis.
