交配

The effects of mating experience and temperature on the production of the female black cutworm moth's sex pheromone were studied in this paper. The results indicated that the mating experience did not significantly affect the production of sex pheromone.

中文摘要：研究了交配和温度对小地老虎雌蛾性信息素产生的影响，结果表明，交配对性信息素各组分的滴度无显著影响，因此不影响小地老虎在下一暗期的再次求偶和交配。

Rats were divided into two groups for mating: group one was rendered pangamy and group two was intervened depending on vaginal smear (n=18 for each group).

按普通自由交配法和涂片干预交配法分两组（各组n=18）进行交配，计算其受孕速度。

Continuous observations using the video recording system showed that in the three biotypes,the earliest copulation events occurred 2-6 h after emergence and 56-73%of females copulated at least once by 12 h after emergence.

3B型烟粉虱与ZHJ2型烟粉虱的生殖隔离程度与同型雌雄虫之间的交配次数和频率相比，B型烟粉虱和ZHJ2型烟粉虱之间的交配次数显著减少，交配频率显著下降。

Mating affects significantly the behavior and physiology of mated female insect:increases the fecundity of female, degreases the attractiveness of males and theacceptance of mating, affects the longevity of mated femal.

交配影响了雌性昆虫的生殖行为和生理，主要表现在三个方面：1，促进雌虫产卵和卵子成熟；2，降低雌虫性诱惑力，抑制二次交配；3，影响雌虫寿命，以上效应我们称之为交配效应。

"But like any other behavior that doesn't lead directly to reproduction—such as aggression or altruism—same-sex behavior can have evolutionary consequences that are just now beginning to be considered," he said."For example, male-male copulations in locusts can be costly for the mounted male, and this cost may in turn increase selection pressure for males' tendency to release a chemical called panacetylnitrile, which dissuades other males from mounting them."

&但是如其他并不直接影响繁殖的行为-如挑衅或利他行为，同性间的性行为也可能产生进化结果，这一点刚开始加以考虑&他说，&比如，蝗虫中雄性之间的交配对被交配的雄性来说代价很大，但同时也增加了选择力，因为雄性接下来会释放一种叫panacetylnitrile的物质，这种物质能阻止其他雄性来跟它交配。&

Scorpion males save themselves by stinging their partners into submission, mantises wait until a female has fed to approach her and spiders actually bring an offering of food in the hope that they themselves will not be the main course.

比如，蝎子的最大敌人竟然是自己，超过一半的雄性沙漠蝎子都是死于交配完成之后的雌性配偶。不过，雄性蝎子自有策略，在与雌性发生性交配前会蛰一下雌性，让雌性完全屈服，以避免雌性交配完成后将其完全吞食。而雄性蜘蛛为了避免不被雌性吞食，它们会用爪子紧紧抓住雌性蜘蛛的下颚，或者为雌性带来了一些食物，从而转移雌性的注意力。

The polymorphism traits were compose d of heterozygosity , number of allele, range of allele-length between the maximum and minimum and informative meioses from reference populat ion and the observed paternal heterozygosity , maximum proportion of ha lf informative mating, observed proportion of half informative mating and informative meioses from experimental population.

分析了62个微卫星在参考群中的杂合程度、等位基因数、等位基因范围和信息配子数与实验群中相应微卫星的父本观察杂合度、最大半同胞信息交配比例、观察半同胞信息交配比例和信息配子数的相关程度，其中父本观察杂合度与最大半同胞信息交配比例相关系数最高为0。

Breedings involving young males proceed smoother if they are paired with experience bitches.

如果初次交配的公犬是与一只有经验的母犬进行交配，整个交配过程会顺利很多。

The B males interfered more successfully with courtships initiated by rival males of another biotype than by males of the same biotype,while indigenous males interfered more successfully with courtships initiated by males of the same biotype than by rival males of the B biotype.

然而，ZHJ1型雄虫和AN型雄虫每次与雌虫交配后就离开，未表现有交配后保卫行为，这便有利于其它雄虫对交配过的雌虫进行求偶。

The results are summarized as follows:(1) Observing and recording copulation events of whiteflies on plants using a video cameraA cost-effective,efficient,and reliable video recording system for observing and recording the mating behaviour of whitefly on live plants was developed.

结果如下：(1)使用摄像机观察和记录烟粉虱在活体植物上的交配行为研发了一套用于观察和记录烟粉虱在活体植物上交配行为的摄像系统，经验证该系统可以准确、连续地观察和记录该虫在较自然状态下的求偶和交配行为。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
