| 摘 要： | 经过水平和垂直地带的性诱观测与室内外调查试验，发现云南桔小寡鬃实蝇年发生４－５代。第二代为主害代，主要为害芒果、桃、番石榴等。成虫诱集高蜂期除柑桔点（高峰期为９－１０月）、甜橙点（高峰期为１０－１２月）外，蓁各点均在６－７月间。各年高峰期早晚和诱集量不同。同年各点成虫高峰期出现的时间也有差异，主要表现为从南到北高峰期推迟。冬季除昆明外，其它各点均可诱到成虫。以高温高湿的西双版纳数量最多。同一地区随

| Abstract: | Based on the horizontal and vertical catches tested by sex attractant traps and in- and out-door investigations, it was found that there are four to five generations of oriental fruit fly Dacus dorsalis Hendel per year in Yunnan Province, its 2nd generation is most important, feeding on mango, peach and guava fruits. The peak period of adult determined by the number caught in traps in most places is in June to July, with the exceptions of citrus and sweet orange orchards in September to October and October to December, respectively. The peak period and number of adult occurrence are different with years; and in a same year, its peak period delayed gradually from south to north, coin-sided with the mature periods of fruit trees. In winter, the adult flies have been caught from all the places except Kunming Area, with the largest population caught in Xishuangbanna, a high temperature and humidity place in the Province. The attracted adult number decreased with the increase of elevation. |
