两种苍蝇密度监测方法的比较分析

Monitoring of fly density with two methods

目的比较笼诱法和粘蝇纸法在苍蝇密度监测中的差异,为选择更合适的苍蝇密度调查和灭效评估方法提供科学依据。方法在同一环境地点中同时布放粘蝇纸和捕蝇笼进行比对试验,分析比较2种方法的监测结果。结果粘蝇纸法的平均密度为6.44只/张,笼诱法的平均密度为1.81只/笼,经统计学分析P<0.01,具有显著性差异。粘蝇纸法和笼诱法所诱捕的优势蝇种均为家蝇,其次为丝光绿蝇,在诱捕成蝇的种群方面两者没有显著差别。结论粘蝇纸法能捕获监测环境中更多的苍蝇,更能真实反映实际的苍蝇密度。

Aim To compare the methods of monitoring fly density by cage trapping and paper-sticking capture. Methods Fly density was monitored in the field with two methods of cage trapping and paper-staicking capture and the results were compared. Results The average density of paper-sticking capture was 6.44/piece,and that of cage trapping was 1.81/cage,showing statistically significant difference between two methods （P〈0.01）. Musca domesica,and Lucilia sercata predominated. Conclusion Paper-sticking capture could caought more flies and reflected the real density of the flies.
