| 摘 要： | 1996年在黑龙江省太兴安岭地区加格达奇附近进行了落叶松球果花蝇（Strobitomyiaspp)的视觉诱捕试验。结果表明．黑胸球果花蝇为该地区的优势种．并首次发现了黄尾球果花蝇进一步探明了该地区落叶松球果花蝇的种团由6种组成。球果花蝇的种团结构及种群的雌雄性比在不同年份，不同林地有变化。挂于树冠上的蓝杯诱辅器诱捕效果优于设在树梢的黄板诱捕器，二者差异显著，挂于树冠南侧的蓝杯请捕器效果明显优于其它三个方位。蓝杯诱捕器对雌雄蝇的诱捕效果因花蝇种群在不同年份的性比变化而有明显差异。

| Abstract: | A research on visual trapping experiment of the files, Strobilomyia spp. infesting Larch cones was carried out at three sites in Daxing'anling, northeastern China in 1996. Strobilomyia melaniola (Fan) is the dominant species among the 6 species of flies damaging larch cones. S. luteoforceps (Fan & Fang) was caught for the first time in Daxing'anling. Species and sex specific response of flies to trap color and trap position were observed. The sex ratio of each species and the ratio among the species of the flies varies in different years and different sites. The effects of blue cup traps hanged upside down on the canopy trapped more flies than that of yellow board traps placed in front of the trees, and blue cup traps hanged on the south of the canopy trapped more than those the east, west and north of the canopy. |
