产卵的

The peak of oviposition was in 6～9d of the female's emergenc e on broad bean.

在相同 条件下，测得每对成虫在蚕豆苗上的最多产卵量及平均产卵量分别是316粒、214.5粒；产卵的高峰期是羽化的6～9d。

This is the season when the dog salmon lays eggs.

In this paper the morphology, behavior, development, survival and reproduction of the parasitoid were studied.

结果表明：白蛾黑基啮小蜂羽化1~2 d爬出蛹壳进行交配、产卵的时间分别为0.5~2 min、1~3 min。

This is the place where Malaysian Plover come to lay eggs, they stay in a couple

An endangered species now, green turtles laid their eggs on the beach in Taiwan in the past. Recently, only a few reserves are left. Wangan Green Turtle Tourism and Conservation Center is one of them where more green turtles regularly come to lay eggs.

绿蠵龟现被列为保育类动物，过去台湾本岛许多沙滩，均有绿蠵龟上岸产卵的记录，如今却只剩下极少数地方，望安乡的绿蠵龟保护区，是目前数量较多且较稳定的产卵栖地。

In fact, first attempts at spawning can be relatively unsuccessful, so a fisheries policy that depends for the most part just on first-time spawners (which is what we are approaching now), could be especially flawed.

实际上，鱼类初次产卵的成活率相对较低。因此，很大程度上依靠初次产卵鱼来维持产量（如果不改变现状，这种问题很快就会出现）的渔业政策是尤其存在缺陷的。

In the past, the diatom-rich blooms nourished the tiny animals that in turn nourished the babies of spring-spawning fish such as perch, which hatch around mid-June.

在过去，富含硅藻的花期滋养了微生物，微生物又滋养了春季产卵的鱼类幼崽，比如在六月中旬产卵的河鲈。

When the spawning weight range from 0.1～2.0g,it has the positive correlation with hatch amount,but when the spawning weight exceeds 2.0g,hatch amount will reduce.(5) Analyse the content of heavy metals and pesticide residues for soil and aquaculture water in W.pigra with the help of atomic absorption spectrophotometers,atomic fluorescence spectrophotometers and gas chromatography.

结果表明，蚂蟥产卵和孵化的最适温度为25℃，产卵的最佳体重为20g左右；温度能影响蚂蟥产卵前后的体重，而体重大小对产卵前后体重变化影响不明显；当卵重在0.1～2.0g之间时与孵出量成正比，当卵重大于2.0g时孵出量反而有所下降。

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).
