【摘要】 1993年对中国东北大兴安岭林区为害落叶松球果的几种花蝇产卵习性进行了观察,结果表明这一区球果花蝇种团可区分出5个产卵类型,但通过扫描电镜对卵的形态观察表明这一种团共有6种,即Strobilomyia lariciola,S.melaniola,S.infrequens,S.baicalensis,S.svenssoni和S.sanyangi。更多还原

【Abstract】 The oviposition patterns of 6 larch cone flies, Strobilomyia spp. , were surveyed in 1993 in Da Hinggan Mountains, northeastern China. The colonization of distinct phases of cone development and the selection of different sites to lay eggs allowed to distinguish 5 patterns of oviposition. Observa-tions of the egg morphology and of the chorion architecture using scanning electron microscope lead to classify the examined cone fly eggs into 6 different types. Each type of egg was related to a given ovipo-sition pattern. Among the 6 egg types, eggs of S. laricicola, S. melaniola and S. infrequens were iden-tified with certainty. Although hypotheses were given, further experiments under controlled conditions are required to identify which of the 3 other egg types is associated to S, baicalensis, S. svenssoni and S. sanyangi, respectively.更多还原
