PH, temperature, amount and adding time of papain, autolysis duration could affect autolysis with external papain to some extent, and the optimum technology conditions were that papain was added by 10×10~4u per kg autolyzed solution at 6 hours after autolysis beginning, pH was adjusted to 6.0, then autolyzed at 55℃ for 26 hours. Suitable adding amount of yeast extract was 0.4 percent of autolyzed solution.

自溶过程中RNA的降解自溶过程中RNA降解的研究表明，在酵母自溶过程中，RNA降解率先缓慢增加，之后迅速上升，最后逐步趋于平衡；而上清液5'-GMP及5'-IMP总量则是先缓慢增加，迅速上升后则又开始下降；pH和温度对于RNA的降解有较大的影响：高压均质及NaCl的添加均能加速RNA的降解，提高上清液5'-GMP及5'-IMP总量，并且可提前上清液5'-GMP及5'-IMP总量开始下降的时间。3。

However,the number of events and frequency of copulation between the biotype B and ZHJ2 decreased significantly compared with those between females and males of a given biotype being placed in one arena, demonstrating a degree of pre-mating partial reproductive isolation between these two biotypes.Although some of the adults of the biotype B and ZHJ2 copulated with each other,mated females produced only male progeny,demonstrating a post-mating complete isolation in reproduction between the two biotypes in cases where copulation has happened.

4B型烟粉虱与ZHJ2型烟粉虱在棉花上的竞争取代过程当B型烟粉虱与ZHJ2型烟粉虱以3：20的比例在棉花上开始竞争，在未喷施吡虫啉乳油的情况下，B型经过6代完全取代了ZHJ2型，并伴随着B型雌虫比例的上升和ZHJ2型雌虫比例的下降；在喷施吡虫啉乳油的情况下，B型取代速度加快，经过5代完全取代了ZHJ2型，也伴随着B型雌虫比例的上升和ZHJ2型雌虫比例的下降；B型单一种群中，雌虫比例稳定在55%～60%；ZHJ2型单一种群中，雌虫比例稳定在50%左右。

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。
