钓鱼苍蝇，you''ll想折幅西施，特别雉鸡尾巴若虫，若虫野兔、铜、多种形式的毛翅。

In Hangchow it has four generations each year and the time of its occurrence is well synchronized with that of the scale.

根据测定，隐斑瓢虫对日本松干蚧各虫态的捕食能力较强，一头成虫的日平均捕食量为：显露若虫13.33头，雌成虫4.27头，卵囊3.67个(每个卵囊内平均有卵265.5粒)，雄蛹28.27只；一头幼虫全期(或2—4龄和3—4龄)分别能捕食显露若虫39.20—105.56头，雌成虫40.80—47.79头，卵囊39.38—41.79个，雄蛹220.50只。

In their infancy the head louse, known during this period as a nymph goes through metamorphoses three times, and every time the nymph will shed its exoskeleton to promote its own growth.

在其起步阶段，该头虱，众所周知，在此期间，作为一个若虫通过金驴的3倍，每一次若虫将摆脱外骨骼，以促进自身的增长。

Of course there is the Hendrickson Nymph, which is a close cousin of the all-time great Mayfly nymph the Pheasant Tail.

当然是hendrickson若虫，这是一个紧密的表弟创出巨大的蜉蝣若虫雉鸡尾。

The development of this psocid can be divided into three stages:the egg,nymph and adult.

结果表明：该虫发育期经过卵期、若虫期和成虫期，其中若虫期有3龄。

Demonstrated by five medicament to 1st age nymphae and prosopon\'s toxicity comparison result that,five medicament obviously are higher than 2~age nymphaes and the prosopon to 1~age nymphae\'s toxicity,explained the Dactylopius confusus along with stadium enlargement,it bears the medicine degree also gradually to enhance, therefore,should prevent and control as soon as possible.

由五种药剂对胭脂虫一龄若虫和成虫的毒力比较结果显示，五种药剂对一龄若虫的毒力均明显高于二龄若虫和成虫，说明胭脂虫随着龄期的增大，其耐药程度也逐步提高，因此，应尽早防治。

There are three instars in the nymphal stages.The mean developmental period from egg to adult was 24.5 days.

从卵发育至成虫平均需24.5d，其中卵期平均9.0d、一龄若虫平均7.4d、二龄若虫平均3.8d、三龄若虫3.5d。

However in Hachijo population, nymphal development was the fastest under LD 12:12h, followed by LD 14:10h and the slowest under LD 16:8h. Nymphal growth is restrained when the nymphs are transferred from LD 16:8h to LD 12:12h at 60 and 120 days after hatching, rapid development is observed when nymphs were transferred in the opposite direction in Hachijo population.

八丈岛种群的若虫在短日条件下发育最快，其次是中间日长，长日条件下若虫发育最慢，孵化后60d或120d将若虫自LD 16：8h向LD 12：12h转移抑制若虫发育，反方向转移的若虫快速发育。

In the Okinawa population, nymphs developed faster under LD16:8h and LD14:10h than under LD 12:12h at constant photoperiods. When photopersodic shifts from long days (LD16:8h) to short days (LD 12:12h) at 60 and 120 days restrain nymphal development, while photoperiodic shifts from short days to long days accelerate the nymphal development.

冲绳种群在长日条件下(LD 16：8h)若虫发育显著快于中间日长(LD 14：10h)和短日条件下(LD 12：12h)的若虫发育，孵化后60d或120d将若虫自LD16，8h向LD 12：12h转移，若虫发育受到抑制，而自LD 12：12h向LD 16：8h转移，则促进若虫发育。

First nymph will get into buds to feed germen by piercing-sucking mouthpart as soon as hatched, which stop flowering and make it becoming galls. From first to 3th nymph complete their development in flower-galls. They have a low death-rate since protection of galls. the 4th nymphs were observed in the end of July at the moment that the period of summer-diapause may begin.

孵化后的初龄若虫即进入未开放的花苞内以刺吸式口器取食子房，致使花苞不能开放而成为虫瘿。1—3龄若虫在花部虫瘿内完成发育，死亡率较低，至7月底发育到4龄若虫时开始夏滞育。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。
