产卵的

Vg could be detected in haemolmph of the water—fed female at 48h after eclosion, too.

用10％的蜂蜜和清水分别饲喂两组成虫(简称"蜜组"和"水组")，以研究成虫期的营养对Vg发生和卵巢发育的影响，结果显示，成虫期营养对于Vg的启动合成并不起关键的决定性作用，两组成虫均可以在羽化的48小时检测到Vg，且水组中的血淋巴水平并不低于蜜组对照，但绝大多数水组个体的卵巢发育停留在卵黄沉积的某一时期，此时在血淋巴中也检测不到，只有约20％的饲水个体卵巢可以发育成熟，出少量卵；用高剂量的ZR515于羽化当日点滴处理饲水个体，可以使所有接受处理的饲水个体的卵巢发育成熟，但是产卵〓依旧低于对照组的，不能恢复正常；这说明成虫期营养对卵巢中全体卵母细胞的成熟是必需的，其作用的产生是通过内分泌系统途径实现的。

Every fact which occurs in the bed, on the banks or in the air over it; the fishes, and their spawning and nests, their manners, their food; the shad-flies which fill the air on a certain evening once a year, and which are snapped at by the fishes so ravenously that many of these die of repletion; the conical heaps of small stones on the river-shallows, the huge nests of small fishes, one of which will sometimes overfill a cart; the birds which frequent the stream, heron, duck, sheldrake, loon, osprey; the snake, muskrat, otter, woodchuck and fox, on the banks; the turtle, frog, hyla and cricket, which make the banks vocal, were all known to him, and, as it were, townsmen and fellow creatures; so that he felt an absurdity or violence in any narrative of one of these by itself apart, and still more of its dimensions on an inch-rule, or in the exhibition of its skeleton, or the specimen of a squirrel or a bird in brandy.

河床上的河岸上的每一个变化，以及空气变化；河中的鱼类及产卵期和汇聚处，它们的行为和食物；河鲱蝇在一年的某天夜里充斥了空气被河中的鱼疯狂吞吃，以至于好多鱼暴胀而亡；在河的浅水湾的一些圆锥形石堆，其中有一个有时能装满一手推车，----这些石堆是一些小鱼的巨巢；那些经常巡游河中的水鸟，苍鹭、鸭子、翘鼻麻鸭、潜水鸟、鱼鹰；河岸的蛇、麝鼠、水獭、啄木鸟和狐狸；还有那使得岸边有了活力的龟、青蛙、雨蛙和蟋蟀----这一切他都熟悉，就像它们是镇子上的人和同类；于是他会感到强烈的荒谬和粗暴在看到任何关于它们的孤零零的描述，以及把它们丰富的内涵压缩在一个方寸的纸上，或展览它们的骨骼，或把一只雀儿和鸟类泡在白兰地酒中保存。

This dissertation dealt with comparing the host-preference in laboratory,searching ability with host plant in cage and greenhouse, crossing relationship amongsome Trichogramma species/strains used to control Ostrinia spp., ovipositon andmating behavior, the dispersal behavior and activity period in daytime, effects ofextracts of corn, mung bean and ECB female scale on searching behavior, functionalresponse, and effect of host eggs stored at low-temperatures on parasitization ofTrichogramma ostriniae. The principal results were summarized as follows

The silkworms, which propagate themselves by ova, grow in the from of larvae and when mature after 4 times of exuviations (about 25 days), they begin to spin silk 0.35g Per worm into cocoons, On completion of this, the worms, having sloughed once again are transformed into chrysalises in the cocoons.

从古代开始，在茂密的桑树中，蚕便一如既往的产卵繁殖，随着一个个完全不同的形态学特征的出现，蚕经历了从蚕卵到幼虫再到成虫的艰辛的成长过程，在整个过程中，蚕将蜕 4 次皮(大约每隔 25 天一次)，接着他们开始土丝来完成茧，当蠕虫与茧达到 0.35 克之后，艰难爬行的蠕虫变成为在茧中的蝶蛹。

Cantly greater numbers of living larvae were found in sugar maple than in the other tree species; however,more were found in red oak and fewer in green ash than expected,considering relative numbers of oviposition sites. After 90 d,mean mass of living larvae did not differ signi?cantly among tree species.

然而，考虑到产卵点的相关数量，我们在红橡树上发现的活的幼虫的量要比预料的多，而在白蜡树上发现的幼虫的量则没有预料的多。90天后，在这些树种上平均幼虫总量已经没有显著的差异了。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
