PCR and electron microscope were used to detect the virus in the ovaries,eggs atdifferent development stages,and naupliuses of infected broodstocks of P.chinensis.Thevirus was not found in eggs just spawned or not,but in the connective tissue of ovary.Thedetected results of nauplius were positive,and virus-like organisms were found to invadethe epidermis tissue of nauplius.The virus was not detected in the yolk as well as inner andouter membrane of egg.

本文利用PCR及电镜技术，对中国对虾染病亲虾的卵巢和各期卵及其刚孵化出的无节幼体进行了病毒检测，染病亲虾刚产的卵及未产出的卵均没有发现病毒存在，在卵巢的结缔组织中检测到病毒存在，刚孵化出的无节幼体PCR检测结果呈阳性，电镜下观测到有病毒样颗粒侵染无节幼体的上层表皮组织。

The body length has great individual diversity normally ranged from 25-60 cm, It also shows strong phototaxy. One lamp can trap more than 2 000 of them per night. Female imago has a large egg load with the maximum amount of 543. The eggs hatching is in depth of 1-3 cm soil. The dominant hatching period of egg is from late June to early July, and hatchability is over 85%. The living space of larva ranges from 15-60 cm in soil.

成虫个体差异大，体长25～63 cm；趋光性强，1个诱集点每晚可以诱集成虫2 000多头；雌成虫抱卵量大，最多达543粒，成虫产卵于1～3 cm深土中，卵孵化盛期为6月下旬～7月上旬，孵化率达85%以上，幼虫在15～60 cm土层内取食危害。

Assisted hatching is when the doctor makes a tiny hole in the shell before the embryo is put back in the womb to help it to hatch.

辅助孵化，是当医生作出了微小的孔在壳前胚胎放回在子宫里，以帮助它孵化。

Before repellency and anti-silverfish assay, the culture system for silverfish was established in this study. The best feeds for silverfish were cellulose and mixed feed in a 1:1 ration (the composition of mixed feed was milk powder: oatmeal: yeast= 1: 9: 9). Moreover, the hatching process was not necessary for the mature of silverfish eggs. According to the results obtained in the repellency assay, the essential oil of leaves and woods from C.

为了进行忌避和致死试验，本研究首先对衣鱼进行饲养及孵化条件测试，於实验后得知最适合衣鱼生长之条件为纸张纤维与混合饲料(酵母粉：麦皮：高蛋白＝9：9：1)混合比例为1：1时之生长状况最佳；另外，衣鱼卵并不需要成虫的孵化，而虫卵的生活条件则与成虫一致。

The females incubated at 33 , their ovarium has powerful cortex, the germinal epithlium produce oocyte, its medulla degenerate into ovarian cavity. During sexual differentiation, mitochondria and smooth endoplasmic reticulum in cells of ovary increase in quantity, they disintegrate after sexual differentiation. There are a lot of big grana in cells of ovary before sexual differentiation, in the course of sexual differentiation the quantity of the big grana decrease, while small grana increase and peakafter sexual differentiation. The males incubation at 26 , cortices of their testes degenerate into a thin albuginea. Medulla are formed by testicular cords in which scatter spermatogonium.

33℃下孵化的小龟卵巢皮质发达，由原始生殖细胞产生卵原细胞，髓质退化成为卵巢腔，分化时卵巢细胞的超微结构显示线粒体和内质网的数量大大增加，它们在分化结束后解体，分化前细胞内有较多的大颗粒，在分化中大颗粒减少，小颗粒增多，在分化后小颗粒达到最多。26℃下孵化的小龟精巢皮质退化成为一层薄的白膜，髓质有许多睾丸管构成，管腔内有散落排列的精原细胞。
