中文摘要:

本研究监测了不同生境下瓜实蝇雄成虫的数量动态，分析了气象因子与其数量变动的相关性。结果表明儋州地区瓜实蝇雄成虫发生低谷为每年12 月和1 月; 从2 月开始，瓜实蝇雄成虫数量逐渐增加，4 － 8 月达到高峰，从9 月开始数量逐渐下降。生境显著影响了瓜实蝇的雄成虫数量，混合菜地、园林区以及混合果园诱集的瓜实蝇雄虫数量多于住宅区、农贸市场、苦瓜地诱集的雄成虫数量。气象因子也显著影响了瓜实蝇雄虫的数量。经逐步回归分析发现瓜实蝇雄虫数量变动受月降水量、月均最高气温、月均最小湿度综合影响，其中月均最高气温是影响瓜实蝇雄虫数量变动的最重要因素。因此，瓜实蝇防控应不仅局限在其寄主园区生境，还应根据其监测的数据对多生境的瓜实蝇进行治理。

英文摘要:

The quantitative dynamics of male Bactrocera cucurbitae were monitored in different habitats，and the correlation between its quantitative fluctuation and climatic factors were analyzed. The results showed that male B. cucurbitae had low valleys in December and January in Danzhou. The population of male B. cucurbitae gradually increased from February，then they had high peaks from April to August. The population gradually decreased from September. Habitats significantly influenced the quantity of male B.cucurbitae. The number of B. cucurbitae in mixed vegetable plot，landscape area and mixed orchard were more than those in residential area，farmer's market and bitter gourd field. Climatic factors significantly affected the quantity of male B. cucurbitae. The stepwise regression analysis indicated that the quantitative fluctuation of male B. cucurbitae was controlled by monthly rain fall amounts，mean monthly maximum temperature and monthly minimum relative humidity，hereinto，mean monthly maximum temperature was the most important factors. Based on these results，the control of B. cucurbitae was not limited in its host habitats. B. cucurbitae should be managed in other habitats arrcording to its monitoring data.
