通过对美国白蛾各个发育期的天敌进行调查与研究，发现除了捕食性天敌七星瓢虫、大刀螳螂等外，幼虫期有2种寄生性天敌、蛹期有12种寄生性天敌，这为保护和利用天敌、有效控制美国白蛾提供了依据。

The biological safety of Bacillus thuringiensis Strain YJ-2000 which acted the low toxicity to Bombyx mori newly hatched larvae and marked insecticidal activity to other lepidopterous insects was evaluated compared with other two Bt strains,i.e.

YJ 2 0 0 0菌株除导致 1龄幼虫历期延长 11 1%、取食量减少 0～ 6 0 0 %及体重降低 5 2 3%～ 6 2 5 %外，对 2龄及其以后各龄幼虫的存活率、发育历期、取食量、眠蚕体重、化蛹率、蛹期、全茧量、蛹重、茧层量、羽化率和产卵量等均无显著影响。

In the artificial rearing larval honeybee method, 1-day-old larvae were reared in laboratory and 0.1 - 100 ppm pyriproxyfen was added in larval food. A dose respondent effect was found in the larval development of the treated larvae. Results showed that 0.1 ppm pyriproxyfen reduced the eclosion rate of the reared larvae conspicuously, and 1 ppm pyriproxyfen reduced that 84.6% of eclosion honeybee appeared the condition of deformed wings. The 10 ppm pyriproxyfen treatment caused 53.8% melanic death in the pupal stage, and no honeybees succeed in eclosion.

在室内饲养幼虫方面，分别添加0.1-100 ppm百利普芬於幼虫食物中，结果显示0.1 ppm百利普芬即会显著降低饲养幼虫的羽化率，而且添加1 ppm百利普芬会有84.6%羽化蜜蜂出现残翅现象；添加10 ppm百利普芬则会造成53.8%蜜蜂在蛹期黑化而死亡，而且无蜜蜂羽化成功；100 ppm百利普芬则有50%蜜蜂在幼虫期死亡，50%蜜蜂在蛹期死亡，亦无蜜蜂成功羽化。

These results have practical value to the control of pebrine disease of the silkworm in silkworm eggs production at present.

在蚕种生产上，经常出现蚕期、蛹期的预知检查无毒，到母蛾镜检时毒率超标而惨遭淘汰的现象。

In addition, Vg was also found in a pupa-specific ectoparasitoid of flies, Nasonia vitripennis (Hymenoptera: Pteromalidae), in which the temporal and titer pattern of transcription and expression of Vg gene was apparently different from that of in Pteromauls puparum.

此外，发现蝇类蛹期重要外寄生蜂-丽蝇蛹集金小蜂也拥有Vg，其Vg基因的转录与表达时序与水平动态明显不同于蝶蛹金小蜂。

The pupal stage was most sensitive to temperature change compared with other developmental stages.

在各虫态中，蛹期的存活率受温度变化的影响最大。

The project implemented a systemic investigation to the pupa period of wild silkworm comparatively, which from Shanxi, Jiangsu, Sichuan, Chongqing, Guizhou provinces and so on. According to the investigation, the pupa dormant characteristic of Shaanxi wild silkworm was found, and the individual, which pupa period was more than two months was selected. Through the hybrid genetic analysis we found that the characteristics for a long period of pupa was controlled by polygene and genetic recessively and strongly influenced by environmental conditions at the same time. To compare the performance of pupa period of the pupa dormant wild mulberry silkworm, we designed different ecological conditions. The result indicating that the temperature is the main factor in the ecological impact, but the pupa period was extended at the same temperature conditions, indicating that the additive effects of the environmental factors.

本项目实施，系统调查比较了陕西、江苏、四川、重庆、贵州等省市的野桑蚕的蛹期经过，发现了陕西野桑蚕的蛹休眠特性，筛选获得了长达2个月以上的蛹期经过个体；通过杂交遗传分析，发现长蛹期特性表现为隐性遗传，受多基因控制，同时受环境条件的强烈影响作用；通过设计不同生态条件比较蛹休眠性野桑蚕蛹期经过的表现，表明温度是主要的生态影响因子，但相同温度的野外型条件下蛹期经过延长，表明受到环境因素的综合作用。

Eggs：卵

生活史一共具有四个阶段,幼虫自纺锤形的虫卵(eggs)中孵化后便开始了一连串的演变. 六脚幼虫(larva)经过一次脱皮后进入蛹期(nymph),具有八只脚,之后再经过几次脱皮后成长为成虫(adult)的阶段. 所有的生活史大约在三周左右完成,

somatic meiosis：体细胞减数分裂

此外某些生物还具有体细胞减数分裂(somatic meiosis)现象,如在蚊子幼虫的肠道中,有一些由核内有丝分裂形成的多倍体细胞(可高达32X),在蛹期又通过减数分裂降低了染色体倍性,增加了细胞数目.

hemimetabola：半变态类

其他绝大多数种类皆进行间接发育:其中半变态类(hemimetabola)历经一定数目龄虫期,全变态类(holometabola)除龄虫期外还要经过蛹期. 半变态昆虫的各龄虫期统称若虫. 它们的形态特点主要是:体区和体节的分化上已与成体一致,

holometabola：全变态类

其他绝大多数种类皆进行间接发育:其中半变态类(hemimetabola)历经一定数目龄虫期,全变态类(holometabola)除龄虫期外还要经过蛹期. 半变态昆虫的各龄虫期统称若虫. 它们的形态特点主要是:体区和体节的分化上已与成体一致,

holometabola：完全變態

2.完全变态(holometabola)虫体自卵孵出后,经幼虫、蛹发育为成虫(图5-2B). 幼虫与成虫不仅形态完全不同,没有外生的翅芽,生活方式及生活环境也多不一致,而且中间一定要经过一个不食不动的蛹期,体内进行剧烈的改造,最后才羽化为成虫.
