化蛹

In P3 , 3 spots of scaleless up-regulated more than two times .

另一种为SP3，在化蛹时开始出现在脂肪体中，一直到成虫期仍可持续表达，因此属于持续性储存蛋白。

In the adult stage only SP-3 was found . SP-3 as persistent storage protein appeared in the fat body of pupa , and was continuously expressed till the adult stage .

化蛹第三天，有3个蛋白点在scaleless中表现出下调，1个点表达量上调。

In the third day after pupation , there are 3 spots down-regulated and 1 spot up-regulated .

蛹期H2O2含量呈下降趋势，化蛹后第3d～5d剧烈变化，此时SOD和CAT的活性也处于高峰值，而且雌雄间出现显著差异。

In the pupae stage , level of hydrogen peroxide decreased and thermally agitated from 3rd day to 5th day . Activities of SOD and CAT were higher and there were significant differences between male and female pupa .

对其化蛹车具有明显的抑制作用，且随条皂素浓度的升高抑制作用越明显，抑制中浓度IC50为15.79ug／g。

And tea saponin had significant inhibition on the pupating rate , the inhibition was more marked along the concentrations of tea saponin increased . The media inhibiting concentration IC50 , was 15 . 79ug / g.

夏威夷的研究表明，阻止辐照过的卵孵化、被处理幼虫蜕皮进入下一龄期或被处理老熟幼虫化蛹，可能需要1000居里（Gy）或更高的剂量。

Research in Hawaii has show that doses of1,000 Gy or more may be required to prevent hatch of irradiated eggs , molting of treated larvae to the next instar or pupation of treated mature larvae .

4月上旬越冬幼虫在木质部内做一椭圆形蛹室化蛹，历时13～15d后成虫羽化。

In the first April , the overwintering larva makes a oval papal chamber in xylem . After 13 ~ 15 days , the adult emerges .

双价棉对棉铃虫抗性种群2～5龄幼虫的死亡率、存活幼虫体重、化蛹率和成虫羽化率等生长发育的影响，均显著高于Bt棉。

Mortality of larvae from 2nd to 5th instar was significantly higher , and the weight of survival larvae , pupation rate and eclosion rate were significantly lower fed on transgenic two genes cotton compared with that fed on transgenic Bt gene cotton .

幼虫孵出后即潜入叶肉取食，经3~4d即老熟，老熟幼虫爬出虫道化蛹的高峰期在6：00~10：00。化蛹在土表至土层3mm深处，这一土层中的化蛹数占总数的80%左右。

The peak of pupation is found during 6:00 ~ 10:00 , the number of pupation in 0 ~ 3mm deep soil layer accounts for about 80 % of the total pupated .

Objective To discuss the susceptibility of insect growth regulators S 31183 ( pyriproxyfen ) to Culex pipiens pallens larva and pupa in the laboratory .

虱螨脲处理的小菜蛾也表现出毒物兴奋效应，其化蛹率和羽化率在低浓度（LC10和LC20）受到刺激升高，在高浓度被抑制而下降。

The DBM treated with lufenuron showed hormesis , stimulate increased pupation rate and emergence rate by low concentrations ( LC10and LC20 ), were decreased by inhibited at high concentrations .

秋天利用5cm土层未冻结前的强寒潮天气，减少越冬虫源；初春进行树下防治，利用土壤小气候特点，恶化越冬茧化蛹的小气候环境，降低虫源基数；

The strong cold currents before soil layer was frozen 5 cm deep in Autumn were made use of to decrease the pest sources and also the small climatic characteristics of soil were used to worsen the small climatic environment when cocoon pupates and decrease the number of pest sources .

幼虫的生长发育明显地受到抑制，幼虫生长缓慢，幼虫期延长，二龄以上幼虫化蛹率极低，处理组120h化蛹率仅为8%，而对照组为79%。
