Chrysopa septempunctata was fed with two foodstuffs, aphids and artificial ovum Trichogramma's pupas. The results indicated that survival time of female worms which intook aphids was obviously longer compared with those which intook artificial ovum Trichogramma's pupas, and their ovum quantity obviously rose. But artificial ovum Trichogramma's pupas can be used as supplementary foodstuff to raise green lacewing because of its factory production.
用蚜虫和人工卵赤眼蜂蛹两种食料来饲养大草蛉的结果表明,喂食蚜虫的大草蛉雌成虫存活时间明显长于喂食人工卵赤眼蜂蛹的大草蛉,产卵量亦明显提高,但人工卵赤眼蜂蛹已经实现了工厂化生产,可以作为饲养草蛉的补充食料。

RESULTS: The growth speed, weight, developmental uniformity, bionergy and fecuncity of the Bombyx silkworm descent dramatically as they eat the feed that the concentration of 2,4-DCP over 0.8 mmol L~-1 or NP exceed 0.500 mmol L~-1. But the effect on reproductive capacity vary with gender difference, it's more obvious on the late-stage of development and periods of metamorphosis such as ecolysis, pupation, edosion. There may be cumulative effect inside the Bombyx siliworm.
结果 家蚕幼虫食下含0.8 mmol·L~(-1)以上浓度的2,4-DCP或0.500 mmol·L~(-1)以上浓度的NP饲料,生长速度、生长量、发育整齐度、生命力和生殖能力都明显下降;生殖能力所受影响应性别而不同;家蚕发育后期和蜕皮、化蛹、羽化等变态时期影响更加明显,在蚕体内可能有累积作用。

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。

After four to ten days, they change again, into creatures called pupas.

The results show that shade of cocoon and reeling silk are all even and bright. Color depth in the cocoon is directly proportional to the concentration of additional pigment. With respect to cocoon color, no difference occurs to the male or female when fed with the same concentrated pigment. Within the range of certain concentrations, the red pigment has little effect on the quality of cocoon and cocoon filament. The red pigment has a fast bond with protein. Color of sericin, fibroin, pupa, moth and egg shell are all red.
结果表明:所营蚕茧及所缫蚕丝色泽均匀、鲜艳;蚕茧的色彩深度与添加的色素浓度呈正比;添食同种浓度的色素所得的蚕茧色彩在雌雄之间无差异;经调查,在一定的浓度范围内红色色素对茧丝质无影响;红色色素与蛋白结合牢固,无论丝胶、丝素还是蛹体、蛾体或卵壳均呈红色。

geometrid moth:尺蛾
常严重伤害或损毁树木. 春尺蠖(Paleacrita vernata)和秋尺蠖(Alsophila pometaria)侵害果树与遮荫树,食去叶肉并在枝条间纺丝. 一般在土中化蛹,唯不结茧. 由於幼虫的行为很具特色,因此尺蛾科有些种称作尺蠖蛾(参阅尺蛾(geometrid moth)条).

colorado potato beetle:马铃薯甲虫
约6公釐(不足0.25吋)长,鞘翅上有三条黑纹. 卵产在马铃薯叶背面,成虫和幼虫均食马铃薯叶,幼虫背面负有粪便以为伪装. 每年两代,第二代的蛹在地下越冬. 於1850年代科罗拉多马铃薯甲虫(Colorado potato beetle)传入之前,是为害马铃薯最严重的甲虫.

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.
