The results in this paper indicated that the main antifreezes in the overwintering larva of D.

不同昆虫种类其抗寒物质的种类和含量不同，在此方面已有较多报道[3]。

Microgastrinae is one of the largest and most important subfamilies in Braconidae.It"s species component is very rich and It"s distribution covers all over the world, all the known species are parasitods of Lepidopteran pests which are the major insect pests in agriculture and forestry. Numerous of them have more value in bio-Logical controll.

小腹茧蜂亚科Microgastrinae是茧蜂科Braconidae内的一个最大和重要的类群，种类多，分布广，已知的寄主全都为鳞翅目害虫，其中有很多的种类有用于农业害虫的生物防治的价值。

Bt cotton and corn may affect natural enemies indirectly by decreasing the population of lepidopteran insects that serve as hosts of parasitoids or predators. Population densities of predators in Bt fields were significantly higher than those in non-Bt fields treated with insecticides for control of target pests.

杀虫剂用量的减少，降低了对天敌的杀伤力，Bt田中捕食性天敌的种类和数量均显著高于常规施药田；但Bt田内靶标害虫数量的减少和质量的降低，在一定程度上影响了寄生性天敌的种类和数量。

Methods: The cyclodextrin, concentration, pH, organic solvent were studied, and the results indicated that the enantiomer of ephedrin and ephedrine levorotatory were baseline separated under the following experimental conditions: uncoated fused silica capillary (75 μm× 68 cm), 25 mmol/L Tris, 2% HP-β-CD and 1% SBE-β-CD, pH was adjusted at 3.0 by phosphoric acid, and 15 kV separation voltage.

以SBE-β-CD和HP-β-CD二元环糊精为手性添加剂，探讨了环糊精种类及浓度、pH、有机溶剂种类等因素对麻黄碱及伪麻黄碱对映体拆分的影响，结果表明：毛细管：未涂渍熔融石英毛细管75μm×68 cm（有效长度60 cm）。分离用缓冲液为25 mmol/L的Tris缓冲液，含2.0% HP-β-CD和1.0% SBE-β-CD，用磷酸调节pH至3.0。

The Bengal Florican is a shy, charismatic species - much loved for its elaborate courtship display.Biologists are trying to learn more about this enigmatic bird.Bengal Floricans Researcher, Lotty Packman:"...the way they jump up and they call and fly down, they're just very unique, very interesting species to be studying."

孟加拉鸨是害羞但又十分有吸引力的种类，它们夸张的求偶表现令人喜爱，生物家希望能更了解这种如谜一般的鸟，它们跳的方式叫的声音及飞下来的样子，它们就是非常独特，研究起来是非常有趣的种类。

Results show that phanerophytes is the dominant life form in the three forests, in which micro-phanerophytes is in the largest proportion, and then followed by hemicryptophytes. In the three communities, the principal leaf size is mesophyl1, the main light eco-form is heliophyle, and the dominating water eco-form is mesophyte.

结果发现，3个群落都以高位芽植物为主，其次为地面芽植物；在高位芽植物中又都以小高位芽植物比例较高；3个群落的叶型谱以小型叶为主，光照生态类型谱以阳生种类为主，水分生态类型谱以中生种类占优势。

Abundance and species number were low in the nearshore than in the offshore of the East China Sea, because most of the pelagic mollusc are offshore water species.

浮游软体动物作为一种偏大洋性的种类，在外海的数量和种类分布要远高于近海。

The results showed that the biomass of every station was distributed inhomogeneously, the polychaeta on biomass was increased remarkably, and the inhabiting density of polychaeta and molluscan were absolutely advantage species.

结果表明，各站位生物量分布不均匀，生物种类上多毛类显著增多，多毛类和软体动物的栖息密度为绝对的优势种类。

Second, the movement of continents has allowed species to move, adapt to new environments, and form new species through natural selection.

其次，大陆的运动允许种类移动，适应新的环境和通过自然选择形成新的种类。

Nematicidal Activity to Different Nematodes of Basidiomycetes from Shenyang CHEN Li-jie, ZHANG Guo-dong, DUAN Yu-xi, LIU Bin, WANG Yuan-yuan (Plant Nematology Laboratory, Shenyang Agricultural University, Shenyang 110161, China) Abstract: The 94 kinds wild macro-fungi of Basidiomycetes were collected from the east of Shenyang around mountains and Shenyang Agricultural University, China. The nematicidal activity of extraction for the fungi were tested with 5 speceies of nematode, including Heterodera glycines, Meloidogyne incognita, Ditylenchus destructor, Aphelenchoides basseyi and Caenarhabditis sp..

沈阳地区大型真菌对不同种类线虫的毒力陈立杰，张国栋，段玉玺，刘彬，王媛媛(沈阳农业大学植物保护学院线虫学研究室，沈阳 110161)摘要：从沈阳市东部山区及沈阳农业大学周边环境采集到94种野生大型真菌，并将采集到的大型真菌制成浸提液，以胞囊线虫、根结线虫、腐烂茎线虫、水稻干尖线虫和小杆线虫为靶标，初步测定了大型野生真菌对5种不同种类线虫的活性作用。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
