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。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
