若虫

Wing bud differentiation initiated at the early 5th nymphal instar, during which the front wing bud cells in the macropterous proliferated much more rapidly than those in the brachypterous. The hinder wing buds of the brachypterous degeneratd at middle 5th instar and finally turned out to be very little wings.

在5龄初始时才发生翅芽发育的分化，之后，短翅型若虫的前翅芽细胞增殖速度明显慢于长翅型，到五龄末期，细胞数量积累明显少于长翅型，短翅型的后翅芽在5龄中期开始退化变短，羽化后变成一个退化的小翅。

Aquatic insects made the greatest contribution to salamander diets, both numerically and by volume, with ephemeroptera nymphs being the most frequently consumed prey type.

水栖昆虫做出了最大的贡献鲵饵料，无论是数控和体积，与蜉蝣目若虫被认为是最经常消费的猎物类型。

Produce 3 generation of 2 ～ one year, with imaginal, egg and each age nymph is mixed in trunk the hibernate on branches and leaves.

一年发生2～3代，以成虫。卵和各龄若虫在主干和枝叶上过冬。

The nymph incubation period, Lagerstroemia Eriococcus resistance is weak and the prevention and treatment of the critical period.

4，若虫孵化期，紫薇绒性薄弱，预防和治疗的关键时期。

The comparative studies on the indirect flight muscle development in both male and female macropterous nymphs showed no difference.

另外，在比较了长翅型雌、雄性若虫背纵肌的发育情况之后证实，间接飞行肌的分化在性别之间无差异。

Biological results showed that the macropterous percentage in male was always higher than that in female in the same population, and the sex of the brown planthopper individuals had no effect on the wing-form of others.

结果表明，褐飞虱雄虫的长翅率总是不低于雌虫，若虫的性别对相同群体中其它个体的翅型分化无影响。

Precocene could induce macropter, the more macropterous adult were found the higher titer of preconece was applied to the larvae, and the macropter inducement was more effective at the 3rd instar than at the 4th instar, the macropterous adults rates were 100% or 86.67% respectively when S. furcifera were treated by 10μg/μl or 100ng/μl preconece at the 3rd instar.

早熟素具有明显的长翅化效应，随着处理浓度的增高，被处理的白背飞虱若虫形成的长翅型成虫数也逐渐增加，且早熟素在3龄期处理对白背飞虱长翅诱导作用强于在4龄期进行的处理，如在3龄期处理时，10μg/μl和100ng/μl的处理组长翅型成虫比率分别高达100%和86.67%。

The results showed that there was no significant difference in the number of adults, nymphae and eggs of E. vitis in all directions of tea trees.

结果表明：假眼小绿叶蝉在茶树各水平方位上的成若虫和卵粒数量差异均不显著；在垂直分布上以上部虫量居多，下部较少。

There were two types for sensilla trichodea. Some bohm bristles formed sensilla cluste r on antenna of nymphae

其中毛形感器有2个类型，若虫触角上的部分蒲姆氏鬃毛组合成弧形感觉簇。

The mineral oil pesticide diluted at 100 and 200 times all had significant lethal effect on L.imitate nymphae, and would not produce the phytotoxicity on longan, so that could be used as medicament for controlling L.imitate of longan.

结论］矿物油杀虫剂100和200倍液对白蛾蜡蝉若虫均有明显的致死作用，且对龙眼不产生药害，可作为防治龙眼白蛾蜡蝉的药剂。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
