Apart from body color of puparial cuticle, there were microstructure differences which were found out by scanning electron microscopy. SEM had denser, more packed structure of the puparial exuviae than that of SEW.

掃描電鏡分析結(jié)果表明，相對于SEW国内揄拍国内精品视频，SEM的蛹表皮結(jié)構(gòu)更加的致密亚洲欧洲中文字幕视频在线观看，表明黑化除了引起蛹的體色發(fā)生變異外，還引起蛹表皮結(jié)構(gòu)發(fā)生了細(xì)微的差異精品一区二区三区无码视频。

In order to identify the mechanism of melanic mutant of S. exigua, genetic regulation on pupae body color, puparial exuviae, phenoloxidase activity, dopamine andβ-alanine of SEW and SEM were investigated.

本文以SEW和SEM為材料99久强奸久久9毛片，分別從蛹黑色性狀的遺傳規(guī)律、多酚氧化酶活力免费色色色色、電鏡分析另类日韩高清精品视频在线观看免费、高效液相分析、多巴胺和β-丙氨酸的微量注射及飼喂誘變幾個(gè)方面進(jìn)行了研究黄色视频免费看在线网站，以期找出甜菜夜蛾黑化的機(jī)理国产色网站农村。

Injection of 0.06mg had no effect on the puparial color of SEM, and injection of 0.06 to 0.22mg ofβ-alanine gave an intermediate phenotype.

注射試驗(yàn)證明，SEM蛹的黑化可能是由于多巴胺的增多或β-丙氨酸的減少引起的大秀视频网。

Whenβ-alanine (0.22mg/insect) was injected into pupae of SEM, the resulting puparial phenotype was similar to that of SEW.

將多巴胺和β-丙氨酸同時(shí)注射入試蟲時(shí)国产每日，蛹的顏色變化不明顯。

The phenotype was partially maintained when β-alanine was co-injected with dopamine. The results indicated that higher level of dopamine, or lower level ofβ-alanine, caused the black puparial cuticle of SEM.

用含有多巴胺和β-丙氨酸的飼料分別飼養(yǎng)SEW和SEM国产极品一线天视频在线播放，也可以誘導(dǎo)蛹的體色發(fā)生轉(zhuǎn)變男人插女人b动态图，但改變的只是表現(xiàn)型，這種表現(xiàn)型不能穩(wěn)定遺傳曰本色色片。
