Mutation rate at exon of GH in five bovine species was very low with the percentage of 3.48%. The majority of nucleotide substitution was nonsense mutation and only one missense mutation was observed. Molecule tree based on haplotypes of bGH at exon 5 showed that differentiation was apparent relatively between Bubalus bubalis and Bos taurus, Bos indicus, Bos grunniens, Bos frontalis. There was no apparent differentiation among other four bovine species and they shared mutual ancestral sequence.

序列分析表明，5个牛种GH基因外显子5的遗传变异水平较低，平均核苷酸变异率约为3.48%，而且绝大多数位点的核苷酸替换是同义突变，仅发现1个错义突变位点；从GH基因外显子5序列单倍型构建的分子进化树来看，水牛与普通牛、瘤牛、牦牛及大额牛的分化相对比较明显，其他4个牛种之间并无明显分化，还享有共同的祖先序列。

In order to provide an scientific basis and technology support to local agricultural by–products export quarantine, an investigation was carried out on the species of stored insects of export agricultural by–products from 2003 to 2005 in the region. The quarantine significance of different stored insects and the insect community structure characteristics of five stored export products were analyzed, besides, a study was conducted on the ecology of Dermestes maculatus Degeer in the laboratory. The main results were as follows. 1. The ordinary and systematic measures were used to investigate stored insect species on export products, such as Willow, Brush, Feather, Leather, Woodwork, grain, coconut funicle, lotus leaf etc., in the finished product, transferring, material reserve and processing storages of the export industries.

为了给该地区农副产品的出口检疫提供科学依据和技术支持，笔者于2003-2005年对江苏沿江地区各类出口农副产品检疫场所的仓储昆虫种类进行了调查，分析了各种仓储昆虫的检疫重要性以及5类出口农副产品仓储昆虫的群落特征，并对重要仓储害虫白腹皮蠹的生态学特性进行了研究，现将结果总结如下： 1、2003-2005年通过对江苏沿江地区的草柳藤制品、笔刷制品、羽绒制品、皮革制品、木制品、粮饲库存点、椰壳纤维、荷叶加工厂等出口企业的成品储藏库、中转库、原料储备库、加工车间等检疫场所的昆虫种类进行了普查和系统调查，共采集标本1800余件，从中鉴定出130种仓储动物，隶属2纲、9目、51科，其中害虫6目、40科、105种，益虫5目、10科、25种；此外，还发现2中国新记录种，即阔鼻谷象Caulophilus oryzae和黑斑豆象Bruchus dentipes。

In order to select strong cold-resistant tree species, seedlings of six tropical and subtropical species (Dillenia turbinata, Peltophorum tonkinense, Garcinia oblongifolia, Alstonia scholaris, Kheya senegalensis and Ormosia pinnate) were treated with the lasting times of 0.5, 3, 5 and 8d at 10℃ respectively. The changes of physiological indices of these seedling were studied.
