Combination of indoor rearing and field observations, in 2008 the overwintering codling moth adult emergence is not concentrated, it began in mid-April. The overwintering generation to reach the peak of adult emergence in mid-May, in early June to late June codling moth adult emergence did not intermittent. In early July being the first generation of adult was eclosion, the emergence period long duration and the peak appeared in late-July.

通过室内饲养和田间观察发现，2008年苹果蠹蛾越冬代成虫羽化不集中，4月中旬成虫开始羽化，5月中旬越冬代成虫羽化达到高峰期，6月上旬到6月下旬苹果蠹蛾成虫羽化没有间断。7月上旬第一代成虫陆续羽化，羽化期较长，在(来源：A904040BC论文网www.abclunwen.com)7月下旬达到高峰。8月上中旬诱捕雄成虫数量逐渐减少。

In order to search condign planting FD alfalfa varieties in transitional areas of farming and pasturing in north, analyzed and compared with productive performance including growing periods、survival rate in winter、plant height、fresh/dry ratio、regrowth character、photosynthetic character、total yield and nutritive content etc of eight different FD alfalfa varieties coming from different countries. The result showed:(1) Varieties between FD2-4 could survive in winter.

为寻找适宜在北方农牧交错区种植的秋眠级品种，对国内外8个不同秋眠级紫花苜蓿品种的生育期、越冬率、株高、鲜干比、再生性、光合特性、总产量及营养成分等生产性能进行分析比较，结果表明：(1)秋眠级2~4的品种均能安全越冬。

Broodstock wintered at at 2~5℃ were fed Nitzschia closterium (30×10^4~50×10^4 cells/mL) supplemented with Chlorella sp. and egg yolk and had a mortality of 1.9%, 4.0% and 9.98% during maturation-inducing. However, the broodstock wintered at below 0℃ were fed the same food and had an increased mortality of 15.87%, 18.8%, 26.27% and 32.07% during maturation-inducing, indicating that there is influence of water temperature on survival of the broodstock during wintering period.

1当水温为2~5℃时，越冬的亲贝在促熟中是以新月菱形藻（30~50万个／mL）为主要饵料，辅以小球藻、蛋黄等，死亡率分别为1.9%，4.0%，9.98%；在0℃以下的越冬亲贝，在促熟中使用同样饵料，则死亡率提高为15.87%，18.0%，26.27%，32.07%，说明亲贝在海中越冬时，水温的高低直接影响亲贝在升温促熟饲育中的成活率。

The secondary root number per plant of Yumai No 49,a mi d-s trength quality wheat,is the smallest among the three varieties except the winte r stage but its root system quality is the best;the intensity of reducing TTC an d the activity of SOD of fresh wheat root are the highest during the period fro m winter stage to flag leaf stage.Since flag leaf stage,its physiological charac ters are weaker and have bigger variation during whole stage.The secondary root number per plant of Yumai No 50,a soft quality wheat,is the biggest except duri ng winter stage,and its dry weight of root of single plant is the heaviest in ev ery stage.Before 19th,March,its intensity of reducing TTC is the weakest and dec reases abruptly after flag leaf stage,but its activity of SOD decreases slowly.R oot dry weight per plant of Yumai No 34,a high quality wheat,is the smallest amo ng the three varieties and its root system quality is the weakest.Before jointin g stage,the intensity of reducing TTC is stronger,but after that,it decreases sl owly though it is smaller,and the activity of SOD decreases slowly in every stag e.

中筋小麦豫麦49号除越冬初期外，其它各时期单株次生根条数均为最少，单株根干重介于豫麦34号及豫麦50号之间，单根质量高；越冬初期至挑旗期，根系活力、根中SOD活性均强于其它两个品种，挑旗后，根系生理活性较小，整个生育期根系生理活性变化幅度大；弱筋小麦豫麦50号除越冬初期外，其它各时期单株次生根条数均最多，单株根干重各时期均为最大；拔节前根系活力最弱，挑旗后根系活力下降幅度较大，根中SOD活性较强且各时期变化幅度不大；强筋小麦豫麦34号，单株根干重最小，根系质量最差；拔节前根系活力较强，拔节后根系活动较弱，下降速度缓慢，根中SOD活性各时期变化幅度较小。

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。

The biological character of the cotton bollworm suggested that it had 3 generations a year, and hibernates with pupa, its larva did harm to the browse, group top, top, tip, flower and boll, the harmful period was about 70 days.

棉田棉铃虫的生物学特性结果表明：棉铃虫在棉田一年发生三代，以蛹越冬，越冬代成虫始见期6月19日，9月中下旬老熟幼虫落入土中化蛹越冬。

Then the number of larvae in the stem increased sharply for a great number of newly-hatched larvae appeared. Though some larvae transferred from stem to root before overwintering, about 43% of the larvae overwintered in tree stems at the height between 40 and 120 cm in the end of September till after the overwintering the next year.

之后，由于初孵幼虫的大量出现，使干部幼虫数量急剧增加，越冬前，虽然有部分转移至根部危害，但到9月末仍有近43%的幼虫停留在树干40～120cm处越冬，直到次年越冬结束。

Factory remaining hot water, remaining vapor and boiler heating system, were adopted in tilapia overwintering. Every step, such as site selection, pond and fish preparation, cultivation of fish, fish selection, timing of overwintering, stocking density and managements during overwintering, was compared among three systems. The results of data analysis showed that the survival rate in remaining hot water system was 12% higher than in remaining vapor system and 21.25% higher than in boiler heating system. The overwintering cost in remaining hot water system was 735 Yuan/m~3, which was 18 Yuan lower than in remaining vapor system and 71.4 Yuan lower than in boiler heating system. The profit in remaining hot water system was 201 Yuan/m~3, which was 162 Yuan higher than in remaining vapor system and 275.4 Yuan higher than in boiler heating system.
