果蝇

A fruit fly's eyes are made up of many individual 'ommatidia' units, stacked together in a dome, with each functioning as a separate lens, producing multiple images that overlap to create a usable picture.

果蝇的复眼由大量单眼组成，单眼排列在一起，形成圆屋顶结构。每一个单眼都可以充当一个单独镜头，产生的多个图像重叠后形成一幅可用的图像。

In Drsophila eye, PCP is evident in the coordinated orientation of ommatidia that rotate 90° in opposite directions in the dorsal and ventral halves of the eye during eye development. The key point for ommatidia to rotate correctly is the decision of R3/R4 fate that is controlled by PCP.

平面细胞极性在果蝇复眼的功能是在发育过程中协调位处背腹部的小眼各自旋转90度，使其依背腹轴形成镜像对称，而要使此过程有正确的旋转角度就要有正确的R3/R4细胞命运的选择，平面细胞极性的作用正是调控R3/R4细胞的选择。

The investigators found that attractive males indeed sired attractive sons.

研究结果表明魅力强的雄性果蝇的后代确实魅力较强。

There were dizzy bees and bow-tied fruit flies turning somersaults and humming in the air.

那里有令人眼花缭乱的蜜蜂和打着领结的果蝇翻着跟头，在空中嗡嗡鸣唱。

Expression of nanos-related genes is associated with the germ line in a broad variety of other taxa.

nanos 基因是一个分布于后部的母效基因，对果蝇腹部以及生殖腺的正常发育是必须的。

Best of all, experiments on fruit flies are not subject to vetting by ethics committees.

果蝇实验最大的好处是不用通过伦理委员会的审查。

The results show that both different banana-attractants and sugar vinegar-attractants had obvious attractive effect to the pest. Among them, banana-attractant (banana : agar solution : honey : vinegar in a ratio of 100:100:30:10) and sugar-vinegar attractant (brown sugar : agar solution : alcohol : vinegar in a ratio of 35:100:30:50) provided a better attractive effect than other analogous attractants, with killing percentages of 77.79 and 94.78, respectively.

结果表明，香蕉诱剂和糖醋诱剂对黑腹果蝇成虫都具有明显的诱杀效果，其中香蕉诱剂配方（香蕉肉∶琼脂水∶蜂蜜∶醋的比例为100：100：30：10）和糖醋诱剂配方（红糖∶琼脂水∶白酒∶醋的比例为35：100：30：50）的诱杀效果比其他配方更好，平均诱杀效果分别可达77.79%和94.78%。

First, scientists bred red-eyed fruit flies from brown-eyed parents.

首先，科学家育成红眼睛果蝇从褐色眼睛的父母。

Then, we construct a coordinate system for terminal bouton of PN in calyx of mushroom body.

然后在果蝇脑的蕈状体萼端定义一个座标系统，用以定位其轴突末梢的空间座标。

The researchers found normal fruit flies that were allowed to socialize took hour-long daytime naps, compared to 15-minute catnaps taken by the isolated insects.

研究者发现普通果蝇中那些能够参与社交活动的一天有1小时左右的打盹时间，而那些单独的个体则只需要15分钟。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
