化蛹

The content of diglyceride in the ovary and the fat body was lower than in the blood.

卵巢和脂肪体中的甘油二脂含量较低，化蛹初期仅2～4％，化蛹5日以后增加到7％左右，到羽化前一直无多大变化，但是，摘除咽下神经节蚕甘油二脂的含量反而高于对照区。

The variation in diglyceride content of the SG removal group was similar to that of the control, but its relative content was higher.

甘油二脂在血液中的含量最高，正常蚕在化蛹初期为23.6％，化蛹5日后增加到49.22％，羽化前下降为33.8％；摘除咽下神经节蚕甘油二脂含量变化与正常蚕相似，但是其相对含量高于正常蚕。

Determined prior to eclosion it was 7% in the control and 2% in the treatment, being significantly higher in the former than in the latter.

卵巢中游离脂肪酸的变化则相反，在化蛹初期较高，有咽下神经节区为14％，摘除咽下神经节区为8％，化蛹7日以后两者均显著下降，到羽化时前者有7％，后者为2％，前者显著高于后者。

Sterol content in the ovary of the normal silkworms was highest (about 18% of total lipids) in the early stage of pupation, began to decrease in the middle stage of pupation and dropped to 7% before egg maturation. When SG was removed, its content in the ovary rose significantly, being about 28% of total lipids by eclosion.

固醇在卵巢中的含量以化蛹初期最高，约占总脂质量的18％，化蛹中期开始下降，到卵成熟时减少到7％左右；但是，咽下神经节摘除后卵巢中固醇的含量显著增加，到羽化前约占总脂质量的28％。

Pupation takes place among leaves on the ground where a silken cocoon is made.

化蛹过程在树叶上进行，它们首先努力作茧，最终化蛹为蛾。

In the early stage of pupation the fatty acid content was about 14% in the control and 8% in the SG removal treatment, and decreased greatly starting from the seventh day after pupation.

脂肪体中游离脂肪酸的含量在化蛹初期较低，化蛹5日后开始增加，到羽化前有咽下神经节区为13％，摘除咽下神经节区为18％，后者显著高于前者。

It was appropriate to feed larva under the reasonable proportion of concentrated feed to succulence, and to culture larva at 2 larva/cm^2 if pupation and propagation were considered while at 4 larva/cm^2 if pupation and propagation were not considered in practice.

5在生产中，饲料以精饲料和青饲料合理搭配为宜，如果考虑化蛹繁殖，密度以2头／平方公分为宜；如果不考虑化蛹繁殖，则黄粉虫幼虫密度可以提高到4头／平方公分。

Larva broods first, first eat by moth feeds bark, eat by moth enters xylem after Feburary, principle of eat by moth is general up; Mature larva spits a kind of limy material to make room pupate before pupate.

初孵幼虫，先蛀食树皮，2月以后蛀入木质部，蛀道一般向上；成熟幼虫在化蛹前吐出一种石灰质的物质作室化蛹。

Our study displayed that HmgD overexpression mutant died as late third instar larvae and malformed pupae during the larvae-prepupa transition,suggests that overexpression of HmgD has effects rather on the third instar larvae stage than on the first and second instar larvae from the mutant could not pupate.

结果表明，HmgD广泛过量表达突变体幼虫在一龄和二龄期发育正常，而在三龄幼虫化蛹时发育异常，发育停滞在三龄幼虫末期至预蛹的阶段，即HmgD过量表达的幼虫不能正常化蛹。

It overwinters as mature larvae in its host gall, pupates in late next March, and the adults get out of their host gall between early April and late May.

该小蜂在北京1年发生1代，11月下旬以老熟幼虫在寄主虫瘿内过冬，翌年3月下旬起化蛹，4月初为化蛹高峰期。4月中旬开始羽化，5月初盛发，5月下旬终止。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
