【摘要】 １９９３—１９９４年，在大兴安岭加格达奇市种子园与母树林内对黑胸球果花蝇Ｓｔｒｏｂｉｌｏｍｙｉａｍｅｌａｎｉｏｌａ（Ｆａｎ）的生物学和生态学进行了观察和研究。视觉诱捕的结果显示，黑胸球果花蝇于５月初羽化，整个羽化期可持续到６月中旬，羽化盛期是在５月中旬，新羽化的成虫在补充营养二周后，２龄幼虫于５月下旬孵化（１龄幼虫在卵内完成发育），３龄老熟幼虫于６月下旬落地化蛹。对该种花蝇的发育与球果发育的同步性，以及与降雨、气温、土表温度的关系也进行了研究。皮尔逊（Ｐｅａｒｓｏｎ）相关系数分析表明：该种花蝇的羽化和产卵与球果含水量密切相关。在６月初，当球果适宜于幼虫取食时，卵大量孵化。同时，对该种花蝇的危害特点和延长滞育现象也做了初步报道。更多还原

【Abstract】 Strobilomyia melaniola (Fan) is the dominant species among the 6 species of maggots damaging larch seed cones in Da Xinganlin, northeastern China.The emergence starts inearly May and lasts until middle of June with peak emergence in mid-May. Ovipositions occurs in late May, 2-3 weeks after supplementary feeding on flowers for newly emerged flies to mature. The examination of cone phenology with development of the fly revealed a close synchrony of the process. Cone water content is found to be amain factor affecting egglaying, whereas larvae enter cones to feed when cone tissues are soft and succulent. Relations of both emergence and oviposition with daily temperature, soil temperature and rain fall are also presented in the paper.更多还原
