雄的

In encounters paired between unfamiliar males and males, there is great difference between dominant male and subordinate one. The dominants approached, attacked and chased the subordinate more often and spent significantly longer time.The subordinates defend or escaped the dominant more often and spent significantly longer time, but there is no significant difference on nonsocial behaviors between the dominant individual and the subordinate one.Frequencies of aggressive and social investigating behaviors are positively correlated with body mass.

结果发现，当陌生的两只雄鼠相遇时，优势雄鼠和从属雄鼠间的社会行为有明显的区别，优势鼠接近、攻击、追赶对方的频次和持续时间明显的多于从属鼠，而从属鼠逃离和防御行为多于优势鼠；优势鼠的体重明显的大于从属鼠，而且攻击行为和社会探究行为的频次与体重呈正相关，非社会行为无明显的差别。

N l male gamete transmission of trisomic 2,7,9 had the relation with chromosome behavior at meiosis and with the degression of pollen activity.Besides,n l male gamete fertilization ability and 2n l embryo development ability perhaps could influnce it,too.

6.2号、7号、9号三体n 1雄配子传递率与减数分裂过程中染色体的行为和花粉生活力的降低有关，同时，n 1雄配子受精能力、2n 1胚发育能力可能也会影响n＋l雄配子的传递率。

Monosomic 3, monosomic 5, monosomic 10, trisomic 4 and trisomic 5 as experiment materials, their meiosis behavior of pollen mother cell, pollen characteristics, physiological and biochemical characteristics of anther, section observation of pollen development and the structure of embryo sac were studied, and the effects on the seed set and transmission rate were analyzed.

本文以大白菜同源四倍体小孢子培养产生的且已鉴定为3号单体、5号单体、10号单体、4号初级三体、5号初级三体的非整倍体株系及二倍体株系等为试材，对各材料的结籽率、雄配子传递率进行了统计，并对花粉母细胞减数分裂行为、花粉特性、花粉发育和胚囊结构以及花药生理生化特性等方面进行了观察研究，进而分析了其对大白菜单体n-1雄配子和三体n+1雄配子传递率的影响。

The calling and copulation behaviour of Ancylis sativa Liu had a dielperiodicity.The female moths began to calling at the first day and increasedto 100% at the second day,then the percentage of calling decreasedgradually from the third day to the fifth day,only 16.7% of females showingcalling behaviour at the sixth day.The effect of environmentaltemperature on calling behaviour of Ancylis sativa Liu was studied duringadult life at 16℃,21℃,26℃ and 31℃.The result showed differenttemperature during adult life affected significantly the calling behaviour ofvirgin females.There was considerable variability in the calling patternsamong the different temperature groups,the higher the temperature was,thelater females called,the shorter the calling behaviour lasted.The copulationbehaviour of Ancylis sativa Liu can be divided into following squence:female calling,male responsing,male approaching female,hairpencil displayingand copulating.

枣粘虫求偶和交配行为研究结果表明，在光周期为14L：10D、温度为21℃下，越冬代枣粘虫雌蛾的求偶高峰期为黑暗期6.0-8.0小时，求偶活动以羽化后1-3天表现强烈，第二天求偶百分率高达100％，第4天开始，求偶百分率下降，到第6天仅为16.7％；环境温度对枣粘虫雌蛾的求偶活动有明显的影响，随着温度的下降，求偶高峰期明显提前，求偶高峰期的持续时间变长，在21、26、31℃下，求偶百分率接近或达到100％，在16℃下，仅为43％；枣粘虫的交配行为可分为雌蛾求偶、雄蛾反应、雄蛾接近雌蛾、打开味刷及交配成功等阶段；交配活动也以羽化后前3天表现强烈；第1、2代在黑暗周期中的交配高峰期比越冬代推后1-2.5小时；越冬代枣粘虫的交尾持续时间多为3-4小时，第1、2代比越冬代短；越冬代交尾前期多为2-3天，第1、2代多为1-2天，少数羽化当天便可交尾；雌雄成虫均有多次交尾习性，雄蛾最高交尾6次，平均3.3次，雌蛾最多交尾3次，平均1.5次，在田间自然条件下，大多数越冬代雌雄成虫只交尾1次，第1、2代交尾次数有所增高，第1、2代成虫交配率明显高于越冬代。

Males with 80.0 g plus body weight and the females with 40.0 g plus body weight,the individuals used in this observation were caught from the lower reaches of the Pusur River,then were acclimated in the pools for 15 days outside the riverbank and fresh escargots meat,Viviparus iaiopoma,were provided as food.

罗氏沼虾在繁殖过程中呈现的典型行为主要有：两性遭遇及识别，雄虾的占位，雌虾的蜕壳，雄虾俘获雌虾及其交媾前的守卫、交媾及精荚传递，雄虾交媾后的守卫及释放雌虾，雌虾产卵及抱卵。

AR signalling can be activated in HR tumours through several mechanisms. First, activation of intracellular signal transduction pathways can sensitize the AR to castrate levels of androgens. Also, mutations in the AR can change AR ligand specificity, thereby allowing it to be activated by non-steroids or anti-androgens. Finally, overexpression of the wild-type AR sensitizes itself to low concentrations of androgens.

HRPC的AR信号通路活化机制包括：胞内信号传导途径可以增加 AR对于去势治疗后低水平雄激素的敏感性；AR的突变也可改变其对于配体的选择，使得非甾体类激素甚至抗雄激素药物也能够激活AR；此外，野生型AR的过表达也促进了自身对于低浓度雄激素的敏感性。

Therefore, we suggest that pollination wasps could be introduced artificially to male syconia of phase B so as to prolong the phase D of male strains; and the match between female and male strains should be 1:2-4, namely, one female strain is cultivated with 2-4 male strains with successive D phases.

因此建议对雄株的B期花序进行人工引蜂的方法修复小蜂种群，从而延长雄性品系D期时长；而雌、雄品系配植模式应为1：2~4，即1个雌株品系与2~4个D期依次衔接的雄株品系配植。
