目的掌握河南省蝇类的种群分布、生态习性及季节消长等变化规律,更好地控制蝇类的孳生与繁殖,为蝇类防治工作提供科学依据。方法采用捕蝇笼糖醋诱饵诱捕法。结果 2008-2011年河南省共捕蝇128 623只,其中大头金蝇、丝光绿蝇和家蝇为优势种,分别占40.28%、24.59%和12.74%。捕获蝇类的总平均密度为54.04只/笼,其中2008-2011各年的平均密度分别为55.57、129.48、22.77、19.44只/笼。蝇类总体的季节消长情况为单峰型曲线,最高峰出现在8月份。结论河南省蝇类主要以大头金蝇、丝光绿蝇和家蝇为主;自2010年后,蝇密度出现明显的下降;河南省蝇类4-10月均有出现,密度最高峰出现在每年的8月份,这种单峰性的分布应与本地的气候有关。本研究整理了近年来河南省的蝇类监测结果,为今后的蝇类防治工作提供了科学依据。
Objective To grasp the distribution rules of flies in Henan Province, ecological habits and seasonal changes and other changes, to better control flies breeding and reproduction, provide a scientific basis for the prevention and control of flies. Methods Catches and catches trap bait trap. Results A total of 128 623 fly flies were collected in Henan province during 2008-2011, of which 10 were dominant species, accounting for 40.28%, 24.59% and 12.74%, respectively. The total average density of flies caught was 54.04 / cage, of which the average density in 2008-2011 was 55.57, 129.48, 22.77, 19.44 / cage respectively. The overall seasonal fluctuation of flies was unimodal, with the highest peak appearing in August. Conclusion The flies in Henan Province are mainly dominated by golden flies, green flies and houseflies. The flies densities have been significantly decreased since 2010, and all flies in Henan Province have been observed from April to October. The highest density peak occurs in each year In August, this unimodal distribution should be related to the local climate. In this study, the results of flies surveillance in Henan Province in recent years were summarized, which provided a scientific basis for the future prevention and control of flies.
