1968年8月至1971年7月,我们在阿尔卑斯山脉对落叶松鞘蛾(Coleophora laricella)的种群动态和复合寄生做了调查。其它学者在室外人工栽植的欧洲落叶松上也做了些类似的研究。种群动态的研究利用是生命表方法。在海拔高度与危害程度不同的三个地方,即Deutscheistrita Gaberl和Unterzeing对落叶松鞘蛾三个世代进行了调查。每一世代采6—7个样枝,每一样枝约30厘米长,约有150—200个枝梢。三年来,对种群的每年波动与消长都进行了描述。1968年至1971年,对越冬代的落叶松鞘蛾进行了调查,种群在上述三个地方分别增长了1.5、6和3倍。落叶松鞘蛾在施蒂里亚山脉的主要死亡因子有冬季鸟类的取食;近缘种类的鞘蛾同时取食针叶时的食物竟争;春天叶芽萌发与幼虫的取食不相吻合;恶劣的天气条件及一些通常不很重要的膜翅目寄生蜂的寄生。寄生落叶松鞘蛾的寄生蜂在阿尔卑斯山脉约20种,其中6种经常且有规律的出现,它们是Dicladocerus Westwoodjj,Chrysocharis,novellus Cirrospilus pictus,Diadcgma nana,Agathis pumila和Habrocytus semotus。有8种为奥地利的新纪录,在寄生落叶松鞘蛾上,首次记载了Teleopterus semotus。比较阿尔卑斯山脉、北欧和北美的寄生蜂组成,发现一些主要的寄生蜂在北欧人造落叶松林内数量稀少或没有,在一般情况下,寄生蜂在阿尔卑斯山脉的种类组成比在欧洲其它地方都要丰富。有些近似种也已适应被引进的寄主,从生存角度讲,它们在欧洲都是近缘种。Agathis pumila是所有寄生蜂种类中对落叶松鞘蛾显示出高度的专一性,而大多数种类确是寡食性或杂食性。落叶松鞘蛾的寄生与其密度呈反比,多数寄生蜂与它们的寄主在发育进度上是不吻合的。经普瓦松方法分析,Agathis pumila和Diadegma nana二者间无重寄生和复寄生现象。
From August 1968 to July 1971, we investigated the population dynamics and compound parasitism of Coleophora laricella in the Alps. Other scholars did similar research on outdoor artificial Larix principis-rupprechtii. The study of population dynamics is the life table method. Three generations of larch shell-moth were surveyed in three locations with different altitudes and degrees of harm, namely Deutscheistrita Gaberl and Unterzeing. Each generation collected 6-7 samples, each sample about 30 cm long, about 150-200 shoots. Over the past three years, annual fluctuations and declines in populations have been described. From 1968 to 1971, surveys were conducted on overwintering generations of C. larvae, with populations increasing by 1.5, 6 and 3 times, respectively, in all three locations. The main mortality factors of C. larvae in the Styrian mountains are winter bird feeding, the competition of coleoptile moths feeding conifers at the same time, and the sprouting of buds in spring does not coincide with larval feeding ; Harsh weather conditions and parasites of some not-so-important Hymenoptera parasitoids. Parasitic larch sheath moth parasites in the Alps about 20 species, of which 6 species often and regularly appear, they are Dicladocerus Westwoodjj, Chrysocharis, Novellus Cirrospilus pictus, Diadcgma nana, Agathis pumila and Habrocytus semotus. There are eight new records for Austria on the parasitic larch shell moth, the first recorded Teleopterus semotus. Comparing the composition of parasitic wasps in the Alps, Northern Europe and North America, it was found that some of the major parasitic wasps are sparsely populated or not in the Nordic artificial larch forests. In general, species composition of parasitoids in the Alps is more abundant than in other parts of Europe . Some of the approximations have also adapted to the hosts that were introduced, and from a survival point of view they are all relatives in Europe. Agathis pumila is a highly specific species of larch shell-mounted moth in all parasitoid species, and most species are indeed oligo-or omnivorous. The parasitic density of Larch sheath moth is inversely proportional to its density, and most parasitic wasps do not coincide with their host developmental progress. After analysis by the Poisson process, there was no parasitism or parasitism between Agathis pumila and Diadegma nana.
