南宁市火龙果产区橘小实蝇成虫消长规律研究

本研究旨在弄清南宁市火龙果产区橘小实蝇成虫田间消长规律,以期为橘小实蝇的预测预报和综合防控提供理论依据。采用甲基丁香酚(methyl eugenol)为诱芯的诱捕器和涂有甲基丁香酚的黄板,在南宁市良庆区那陈镇西宁村和南宁市邕宁区蒲庙振企农业科技有限公司两大火龙果基地设置了14个监测点,诱捕监测2018年～2019年的橘小实蝇Bactrocera dorsalis成虫消长动态并根据当地气象资料分析气象因素与橘小实蝇成虫活动数量的关系。结果表明,橘小实蝇诱捕高峰期发生在7月下半月～9月下半月,12月下半月~次年3月下半月未捕获到成虫；气温是影响当地橘小实蝇活动的主要气象因子。

Study on the population dynamics of Bactrocera dorsalis (Hendel) adults in pitaya-producing areas in Nanning

The purpose of the research is to find out the population dynamics of Bactrocera dorsalis (Hendel) male adults so as to provide theoretical basis for prediction and comprehensive prevention in pitaya-producing areas in Nanning. Methyl eugenol was used as lure core on the trap and yellow sticky, and the experiment was set 14 monitoring stations in Xining Village and Zhenqi Company from 2018 to 2019 which for monitoring dynamics of B.dorsalis adults and analyzing the relationship between local meteorological data and adult activity of B.dorsalis. The results showed that the trapping peak of B.dorsalis between late July to late August, it began to stop activity from late December to late March. Temperature is the main meteorological factor affecting the local population dynamics of B. dorsalis.
