There was no significant difference in larval survival, sex ratio, pupation and adult emergence among four genotypes.

结果表明，抗性基因型在产卵量、卵孵化率、幼虫及蛹历期和成虫存活期等方面与敏感基因型相比较存在明显的不利性；与敏感基因型相比，抗性基因型只有045的适合度，RS和SR基因型的相对适合度分别为114和108。

Tabaci was the shortest (19.3 d) on hairy gourd and the longest (29.0 d) on bitter cucumber, the survival rate from egg to adult was the highest (92.85%) on cucumber and the lowest (53.08%) on bitter cucumber, the laid eggs were the most (187.4 eggs per female) on cucumber and the least (30.0 eggs per female) on bitter cucumber, and the longevity was the longest (25.2 d) on cucumber and the shortest (10.9 d) on bitter cucumber. The intrinsic rate of increase r(subscript mon cucumber, hairy gourd, bitter cucumber, and sponge gourd was 0.1453, 0.1429, 0.0616, and 0.1055, respectively.

结果表明，B型烟粉虱在节瓜上的世代发育历期最短，为19.3d，在苦瓜上的世代发育历期最长，为29.0d；世代存活率在黄瓜上最高，为92.85%，在苦瓜上最低，为53.08%；平均单雌产卵量在黄瓜上最多，为187.4粒，苦瓜上最少，为30.0粒；雌成虫寿命以在黄瓜上最长，为25.2d，在苦瓜上最短，为10.9d.B型烟粉虱在黄瓜、节瓜、苦瓜和丝瓜上的内禀增长率r(下标 m分别为0.1453、0.1429、0.0616和0.1055。

During spawning, red drum males attract females by producing a drum-like noise by vibrating a muscle in their swim bladder.

在产卵，红鼓男性吸引的生产鼓样噪音振动他们游泳膀胱内的肌肉的女性。

Based on the data obtained in 2001 ～ 2003 from 33 stations, the secondary production of macrobenthos from the anchovy spawning ground in the southern Yellow Sea was studied using Brey's (1990) empirical formula. The results showed that the mean abundance was 194.3 ind.

根据2001至2003年南黄海鳀鱼产卵期在鳀鱼产卵场33个站考察采集的大型底栖生物定量样品资料，利用Brey's(1990)的经验公式对调查海区进行了大型底栖生物栖息密度、生物量、次级生产力和P/B值的研究计算。

Result shows that the Apriona germari adult insect prefer to eat Broussonetia papyrfera and reject to eat other tree species which result in difference in natural life and fecundity. Total sugar and dissolvable protein content in the bark is not the cause of rejection. Difference of dissolvable sugar and amino acid may be the reason of preference while difference of dissolvable phenolics and tannin content may explain the rejection.

取食构树的桑天牛成虫取食量大，存活时间长，产卵量大，遗卵量少，其他3个树种则相反。4树种树皮内总糖和可溶性蛋白含量与桑天牛抗性无关，树皮内可溶性糖含量、总氨基酸和必需氨基酸含量对抗性有一定影响。4树种树皮内水溶性总酚含量和单宁含量差异对成虫取食有较大影响，酚类和单宁等次生物质对桑天牛成虫的忌避作用是导致抗性的主要原因。

There has been lots of researches on 5-HT's role in Caenorhabditis elegans feeding, oviposit and locomotion behavior, however no research was about mechanisms on C. elegans learning and memory regulation.

迄今，在线虫中有诸多关于5-HT参与调控线虫的进食、产卵以及运动等行为的报道，然而有关5-HT参与调控线虫的学习记忆行为方面未有涉及到。

When tHe female have taken enough blood and dropped from donkey's body,they wereput in incubator to oviposit and incubated at 28℃ and 90%RH.

将实验室培育的&清洁&草原革蜱饥饿成虫，饲喂在人工感染驽巴贝斯虫的驴体上，俟雌虫饱血脱落后，置28℃、相对湿度约90％的培育箱中产卵孵化

Live plants are also a beautiful, functional addition to your saltwater aquarium, as they serve to help oxygenate the tank and provide the fish with a spot to inhabit and, if you are incredibly lucky, lay their eggs.

植物也有美丽的，功能除了您盐水水族馆，为他们服务，以帮助氧化的坦克和鱼类提供了栖息场所，如果你是令人难以置信的幸运，产卵。

One is the South American phorid fly, it lays its eggs on fire ants, when the eggs break open, the young flies eat the brains of the ants. But researchers don't know how well the flies would do in North American.

他们在火蚁身上产卵，当卵破壳的时候，幼蝇就会吃掉蚂蚁的脑子，但是科学家不知道这种苍蝇对于北美的影响。

Other natural ways to fight the fire ants are also possible. One is the South American phorid fly. It lays its eggs on fire ants. When the eggs break open, the young flies eat the brains of the ants.

另外的通过自然方式抑制火蚁的途径也可行，其中之一是南美蚤蝇，这种蚤蝇可以在火蚁身上产卵，当卵孵化后，幼蚤蝇就会吃掉火蚁的脑。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
