蝇

Diptera is a fly Tephritidae, is an important fruit and vegetable pests are known to the world more than 4000 kinds of fruit flies, known in China about 400 kinds of fruit flies, the danger of fruit and vegetable crops or pose a potential threat to an important type of account More than 50 countries provided for in quarantine fly nearly 20 categories.

实蝇属双翅目实蝇科，是重要的果蔬害虫，全世界已知实蝇4000多种，我国已知实蝇约 400种，危险性或对果蔬作物构成潜在威胁的重要种类计50余种，各国规定的检疫实蝇类近20种。

After 72 h,168 h to observe amount and species of the attracted flies by the six materials in the three fields.Results There is amount difference of flies among three fields( P ≤0.01).There is also species difference of flies among six materials;In six materials,"canker fish+bean draff"(3∶2) attracted the most flies.The following is "canker fish+bean draff(3∶2)+ 0.1% TH6040".

结果在3种环境下，不仅6种诱蝇材料72h、168h诱捕的蝇数有很大的差别( H =10.80，χ2≤0.01； H =10.80，χ2≤0.01)，而且各诱蝇材料诱捕的蝇类种群构成亦有所不同；以腐鱼肚肠及豆渣(3∶2)诱蝇数量最多，其次为腐鱼肚肠及豆渣(3∶2)加0.1%灭幼脲；在同一环境，各诱蝇材料间差别亦很大。

The time needed for the development of flies fed with the Beijing Recipe is longer than that of flies fed with Wurzburg Recipe . The former showed hyperfunction in courtship, less female fertility, and lower performance indices compared with those of fed with B.

用北京配方培养的果蝇发育时间比用Wurzburg配方的果蝇延长，A培养基培养的果蝇在求偶方面表现出亢进，雌蝇单位时间内的产卵率低于B培养基中的果蝇，而且A培养基培养的果蝇学习记忆能力低于B培养基中的果蝇。

Voiceover of Norman Maclean: In the afternoon, we would walk with him while he unwound between services .

假蝇有干蝇和湿蝇之分：干蝇在水中不下沉，浮在水面上；湿蝇在水中下沉。

The Drosophila heart related genes, tinman and wingless, have been shown to play an important role in coordinating the early formation of heart progenitor cells and precursors, yet the late function is still unexplored.

虽然果蝇心脏发育基因wingless和tinman在果蝇心脏发育的早期功能已经清楚，它们都与果蝇心脏前体细胞的形成有关，但它们在果蝇心脏发育的后期功能仍有待进一步研究。

Capitata. The detecting probes included one family probe, one genus probe, three related species probes and four species specific-probes, and the quality-control probes included anchor probe, positive probe, negative probe and blank probe, with one for each. The results of gene chip showed that the specificity of detecting probes was specific to distinguish the three Ceratitis fruit flies.

地中海实蝇及其近缘种检测芯片由检测探针（实蝇科通用探针1条，小条实蝇属通用探针1条，地中海实蝇、芒果小条实蝇和纳塔尔小条实蝇近缘种探针2条和种特异探针4条）、质控探针（定位点探针、阳性质控、阴性质控和空白对照探针各1条）组成。

Results There was no significant gene difference between adults and larvae. CO Ⅱ gene sequences could he used to identify Boettcherisca peregrina, Aldrichina grahami and Lucilia illustris but they could not distinguish Lucilia cuprina from the Lucilia sericata because of their close evolutionary distance and single nucleotide polymorphisms in aldrichina grahami and Lucilia illustris populations were found.

结果 成虫与幼虫基因差异不明显，COⅡ基因序列可以对棕尾别麻蝇、巨尾阿丽蝇和亮绿蝇进行鉴定，铜绿蝇与丝光绿蝇进化距离较近，COⅡ序列不能将他们区分开，同时还发现巨尾阿丽蝇和亮绿蝇存在种群单核苷酸多态性。

Ophyra aenescens (Wiedemann,1830),which distributed in Palaearctic,Nearctic,Australia and Neotropic Regions,but not known to China before,was recently found in Shanghai,China.It was also intercepted from waste paper in a cargo from America and Australia.The present paper deals with the diagnostics,biology,distribution and others of the species.

2001年3月在浦东国际机场附近一孔雀尸体上发现1种中国前所未见的黑蝇，被疑为近年从境外传入，该种黑蝇被鉴定为古铜黑蝇〔 Ophyra aenescens (Wiedemann，1830)〕，原产于美洲，可携带脊髓灰质炎病毒、沙门菌、志贺菌等，是一种重要的病媒性蝇类；2002～2004年在上海其他地区的调查中，也采到了该种；上海口岸于2003年12月22日从美国和2005年4月22日从澳大利亚的入境废纸中先后截获该蝇。

In fly casting the weight of the line carries the fly to the fish.

飞蝇是用特制飞蝇线的重量把飞蝇抛往鱼儿，使用飞蝇需要学会着么使用飞蝇钓竿与飞蝇线的重量把线抛出。

I have therefore generated several p130cas RNA interference transgenic lines to determine the possible function of p130cas during neurogenesis. Knockdown of p130cas expression in developing neurons resulted in partial fusion in the commissures axon fascicles of CNS, photoreceptor axon targeting and guidance defects, and bulged synapse boutons at the neuromuscular junction. Moreover, reduced expression of p130cas in sensory organ precursor cells and proneural clusters resulted in bristle development defects.

为了了解p130cas的功能以及更进一步的分析p130cas在神经发育过程所扮演的角色，我建立一系列可以执行RNA干扰技术的转殖果蝇，结果显示在果蝇的神经中降低p130cas的表现会造成腹部神经索中原来排列整齐的commissure axons神经束偶尔会出现不正常的融合；若将p130cas专一地在果蝇眼睛中降低则会造成果蝇视神经突触目标辨识与突触导向的缺陷；而如果局部的运动神经系统中降低p130cas的表现会造成在神经肌肉接点的神经突触有澎大的现象；此外在果蝇的感觉器官前细胞以及原神经细胞丛，降低p130cas的表现则会导致刚毛发育的缺陷。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
