１９９３年４～９月与法国农科院合作，对东北地区兴安落叶松和红皮云杉球果种实害虫危害调查的初步总结得出：危害兴安落叶松球果的害虫以球果花蝇（Ｓｔｒｏｂｉｌｏｍｖｉａ）属为主，共５种，落叶松球果花蝇［Ｓ．ｌａｒｉｃｉｃｏｌａ（Ｋａｒｌ）］。贝加尔球果花蝇［Ｓ．ｂａｃｉｃａｌｅｎｓｅ（Ｅｌｂｅｒｇ）］、黑胸球果花蝇［Ｓ．ｍｅｌａｎｉｏｌａ（Ｆａｎ）］、稀球果花蝇［Ｓ．ｉｎｆｒｅｑｕｅｎｓ（Ａｃｋｌａｎｄ）］和斯氏球果花蝇［Ｓ．ｓｖｅｎｓｓｏｎｉＭｉｃｈｅｌｓｅｎ］。其中斯氏球果花蝇在我国是首次报道为新记录。这几种花蝇造成的落叶松球果被害率、其中有些地区可达１００％，平均为６３％。以黑胸球果花绳为绝对优势种，占花蝇种群数量的５３％。兴安落叶松种子的主要害虫是落叶松种子小蜂（Ｅｕｒｙｔｏｍａｌａｒｉｃｉｓｙａｎｏ），危害率为３３％。云杉球果小卷蛾［Ｃｙｄｉａｓｔｒｏｂｉｌｅｌｌａ（Ｌ．）］是红皮云杉的主要害虫，危害率可达９５％，其次是球果螟［Ｄｉｏｒｙｃｔｒｉａａｂｉｅｔｅｌｌａ（ＤｅｎｉｓｅｔＳｃｈｉｆｆｅｒｍｕｌｌｅｒ）］。
From April to September of 1993, in cooperation with the French Academy of Agricultural Sciences, a preliminary survey on the investigation of the hazards of larch and spruce coniferous fruit pests in the northeast of China was conducted. The results showed that: (Strobilomvia) genus, a total of 5 species, larch Conesfly [S. laricicola (Karl)]. Siberian fruit flies [S. Bacicalense (Elberg)], black-billed fly [S. melaniola (Fan)], Drosophila melanogaster [S. infrequens (Ackland)] and Ssp. svenssoni Michelsen]. Among them, Sesamia foetidus was first reported as a new record in our country. Larch cones damage caused by these types of flies, in some areas up to 100%, an average of 63%. With black chestnut flower rope as the dominant species, accounting for 53% of the population of the flower flies. The main pest of Larix gmelinii seeds is Larch (Eurytomalaricisyano), with a hazard rate of 33%. Cyadostrobilella (L.)] is the major pest of Picea koraiensis, with a hazard rate of up to 95%, followed by Dioscorea nipponica [Dioryctriaabietella (Deniset Schiffermuller)].
