摘 要 ：1988年和1989年,我们分别对大、小兴安岭危害落叶松的球果花蝇(Strob-ilomyia spp.)种群进行了定点观察研究。在大兴安岭,种群由S.laricicola(Ka-rl)、S.baicalensis(Elberg)、S.infrequens(Ackland)和S.melaniola(Fan)组成,其中S.melaniola为优势种。在小兴安岭,种群由S.luteoforceps(Fan & Fang)S.batcalensis(Elberg)、S.infrequens(Ackland)和S.melaniola(Fan)组成,其中S.infrequens为优势种。利用黄色胶纸诱捕成蝇,发现各种类羽化期不同,进而幼虫的发育期也不同,并与落叶松球果的物候同步。各种球果花蝇在球果上产卵位置不同,因而其为害状也不相同。

Abstract:From 1988 to 1989, the authors conducted fixed-site observation on thelarch cone fly complex (Strobilomyia spp. ) in the Da Xingan and the Xiao Xi-ngan Mts. In the Da Xingan Mts., the complex is composed of S. laricicola(Karl), S. baicaleneis (Elberg), S. infrequens (Ackland) and S. melaniola(Fan). S. melaniola is the prominent species. In the Xiao Xingan Mts., thecomplex is composed of S. luteoforceps (Fan & Fang),S. baicalensis(Elberg),S. infrequens (Ackland) and S. melaniola (Fan). S. infrequens is the domi-nant species. Yellow-glue paper trapping shows that each species has different emergingperiod and so the larval developing period is different from each other; alsothe developing period is accordant with the cone development.
