The clinical test achieved 100% efficacy to kill bovine hypodermosis larvae with 10%.fenthion spot-on. The infection ratio of bovine hypodermosis declined from 30% to 0. Moreover, there was no one poisoned cattle.

用10％倍硫磷点涂剂对30头牛进行临床防治试验，表明该浓度的倍硫磷点涂剂对牛皮蝇第一、二期幼虫杀灭率为100％，可使牛皮蝇蛆的感染率由30％降至0，防治中无1例牛发生中毒。

The trails were carried on Drosophile and Hypodermosis in yaks.

试验表明，在饲料中添加1μg/mL他汀类药物，果蝇的生长发育就可被有效抑制；感染皮蝇蛆的牦牛一次口服100mg他汀类药物，感染率成功率可从80%下降到40%，感染强度从6.8下降到2.4。

The main results and conclusions are as followings.1, The histone deacetylase inhibitors were used to feed the larve of the fly, and then the polytene chromosomes were observed under the microscope.

得到的主要结果和结论如下： 1，通过用去乙酰化酶抑制剂处理果蝇幼虫，观察果蝇多线染色体在热休克基因处的形态变化，发现去乙酰化酶抑制剂介导的乙酰化水平的升高可引起染色体结构的显著变化，推测乙酰化修饰不仅影响分子间的相互作用而且还可以影响染色体的高级结构。

Objective To solve the difficulties of identification of Sarcosaphagous flies such as Lucilia sericata and Lucilia cuprina which could not be identified by analyzing the 278 bp and 635 bp regions of the gene encoding for cytochrome oxidase subunitⅠand Ⅱ in mtDNA.

目的通过mtDNA上16SrDNA中551bp基因序列分析，解决依据COI和COII上278bp和635bp基因序列难以鉴别丝光绿蝇、铜绿蝇种类的难题，为法医学嗜尸性苍蝇种类的鉴别提供依据。

To investigate the effects of morphine on the growth of Lucilia sericata larvae or pupae,and the deduction of decedent postmortem interval based on it,rabbits were injected with different doses morphine hydrochloride and killed,and their muscles were used to feed the newly-hatched L.sericata larvae.

用盐酸吗啡注射家兔，处死后用家兔的肌肉组织饲养丝光绿蝇初孵幼虫，研究吗啡对丝光绿蝇幼虫和蛹生长发育的影响及其在法医学中推断死者死亡时间方面的应用。

At present, the life of the tea on the Drosophila study on the impact of major black tea, green tea, Lingzhi tea, mountain Mallotus and so on, over the course of the study of fruit flies were found in tea to increase the impact of life expectancy, among the best green tea .

中文摘要：目前国内茶对果蝇寿命影响的研究主要有红茶、绿茶、灵芝茶、山苦茶等，在以上的研究过程中均发现茶叶对果蝇有提高寿命的影响，其中又以绿茶效果最佳。

TO examine whether there is SD system in natural populations of Drosophila melanogaster in China, we surveyed a few populations of D.

在此基础之上，进一步从北京北安河地区的黑腹果蝇群体中筛选得到一个SD果蝇品系。

Our previous studies have shown that ubiquitous overexpression of HmgD caused hemocytes proliferation and the formation of melanotic tumors in the Drosophila larvae. To clarify the mechanism of melanotic tumors appearance,we also generated RT-PCR analysis to test the transcriptional changes of PPAE and Spn27A,which encode the key factors in the phenoloxidasecascade pathway from larvae samples of mid-third instar,late-third instar and prior to pupation relative to wild type flies.Our result showed that in the HmgD overexpression mid-third instar larvae,the expression level.of Spn27A was lower than wild type,otherwise the expression level of PPAE was higher than wild type.It suggests that overexpression of HmgD affects the PO cascade pathway.

本研究组前期工作发现，过量表达HmgD引起果蝇幼虫体内血细胞增生，并出现黑色素瘤，为探讨HmgD过量表达导致了血细胞增生即形成黑色素瘤的分子机制，本研究分别提取三龄中期、后期和相对于野生型化蛹前时刻的幼虫的RNA，首先检测了编码酚氧化酶级联反应途径中的两个关键基因PPAE，Spn27A在突变体中的转录发生变化，结果发现，Spn27A在三龄中期的表达量低于野生型，而PPAE的表达高于野生型，表明过量表达HmgD影响了酚氧化酶级联反应途径，低水平的Spn27A不足以抑制PPAE的活性，活化的PPAE催化了PPO的活性，使其转变成有活性的PO，从而促进黑色素的生成，使果蝇体内产生黑色素瘤。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
