Result The central leaves of the plants were dehydrated and wilting, or the leaf was broken from the basal part of the leafstalk or rachis after the stem was damaged by the R. ferrugineus larva. The larva could leave regular boring holes on the plant pinna or lobe.

结果］红棕象甲幼虫蛀茎会导致植株心叶脱水垂软，后干枯，或者叶于叶柄或叶轴基部折断，幼虫蛀蚀会在植株羽片或裂片上留下整齐的蛀蚀孔。

Among the sixteen experimental fishes, they can parasitize and metamorphose successfully on only 5～6 fish species.

实验表明：该幼虫对寄主鱼有一定的选择性，在所试16种鱼中，幼虫只能在5种鱼体上成功地寄生，并变态为幼蚌。

The ultrastructure studies show that the number of mitochondria in the motor neurons from resistant strain are higher than those of the susceptible strain, and the thickness of neural lamella and perineurium of resistant strain is thicker than those of the susceptible insects.

棉铃虫抗性种群、对照种群、同种群不同龄期幼虫以及同一个体胸、腹神经节的神经细胞体外培养时形态无明显差异，但抗性品系幼虫运动神经元内线粒体明显增多，且神经围鞘与神经节膜厚度之比明显增加。

Methods The necrophagous fly L. sericata were reared at constant temperature of 20 ℃, 24 ℃ and 28 ℃ respectively and were tempted to lay eggs with lean pork. One Sample was taken at 12 h intervals till 50% of the larvae were in pupae stage. Then, the anterior spiracle, posterior spiracle and cephalopharyngeal skeleton were investigated through digital image processing combined with morphologic observation.

在20 ℃、24 ℃和28 ℃下饲养丝光绿蝇，瘦猪肉诱其产卵，每隔12 h取样1次，直至50%以上幼虫化蛹为止，采用形态观察与图像分析相结合的方法对幼虫前气门、后气门、头咽骨进行观察研究。

The cells in the centre of the trochophore showed very strong positive NSE and strong positive POD.

在担轮幼虫期，中央的内脏团原基呈NSE极强阳性或POD强阳性，其余细胞则呈NSE强阳性或POD阳性。D形面盘幼虫期，外套膜和内脏团呈NSE极强阳性或POD强阳性，其余部位则呈NSE强阳性或POD弱阳性。

The linear relationship between creaturely activity for alcohol, aether, ketone and ester and the molecular topological index is obtained.

研究了醇、醚、酮和酯对水生生物毒性、蝌蚪麻醉活性、沙镯幼虫麻醉活性、番茄植物毒性、红蜘蛛毒性、藤壶幼虫麻醉活性、局部麻醉剂活性和小鼠毒性等八种生物活性分别同其分子连接性指数的相关性。

Larva broods first, first eat by moth feeds bark, eat by moth enters xylem after Feburary, principle of eat by moth is general up; Mature larva spits a kind of limy material to make room pupate before pupate.

初孵幼虫，先蛀食树皮，2月以后蛀入木质部，蛀道一般向上；成熟幼虫在化蛹前吐出一种石灰质的物质作室化蛹。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
