2018年寿光市洪灾后6乡镇蝇类密度监测
|
摘要
目的了解寿光市2018年8月洪灾后蝇类密度情况,评价短期内洪灾对其消长的影响,为下一步全面实施蝇类防控措施提供依据。方法分别于9月1～2、8日先后对受灾最严重的6乡镇蝇密度采用目测法进行2次统一监测。结果第1次监测:成蝇密度平均为16.54只/m~2,其中进水村为19.23只/m~2,未进水村为13.85只/m~2;垃圾堆放场所密度最高为42.79只/m~2。蝇幼虫孳生率为5.51%,其中进水村为5.21%,未进水村为5.94%。第2次监测:成蝇密度平均为1.89只/m~2,其中进水村为1.25只/m~2,未进水村为2.53只/m~2,垃圾堆放场所密度最高为3.46只/m~2。结论洪灾引起蝇密度异常升高(结合2017年同期成蝇密度7.83只/m~2),灾后及时采取蝇类防控措施效果明显。
Objective To understand the flies density after the August 2018 flood in Shouguang city,and evaluate the short-term impact of the flood on its fluctuation and growth,so as to provide the basis for the further comprehensive implementation of flies control measures. Methods Visual observation method was used to monitor the flies density twice in 6 towns and villages that were seriously affected by flood on September 1 st-2 nd and 8 th. Results From September 1 th-2 nd,the average flies density was 16.54/m~2,among which the flies density was 19.23/m~2 in the waterflooded villages and 13.85/m~2 in the non-waterflooded villages;the maximum density in garbage stacking place was 42.79/m~2.The breeding rate of flies larvae was 5.51%,among which was 5.21% in waterflooded villages and 5.94% in non-waterflooded villages.On September 8 th,the average density of adult flies was 1.89/m~2,among which the flies density in waterflooded villages was 1.25/m~2,and in non-waterflooded villages was 2.53/m~2,the highest density in garbage stacking place was 3.46/m~2. Conclusion The flies density increased abnormally after the flood(combined with the flies density of 7.83/m~2 in the same period of 2017),taking prevention and control measures in time after the flood is effective.
