长翅

In the first chapter, using fragments of COI gene, we studied the phylogenetic relationships among species of five familes of Acridoidea with MP and Bayesian methods. The results were as follows:(1) Species of Acrididae, Gomphoceridae and all the Arcypterinae species of Arcypteridae are monophyletic. Species of Oedipodidae are supported as a monophyleticgroup, Ceracrinae species of Arcypteridae cluter together to make a monophyletic group. Epistaurus aberrans and Xenocatantops humilis is a phylogenetic group, Stenocatantops splendens and Hieroglyphus banian is also a phylogenetic group.

我们首先利用COI基因序列片段，使用最大简约法、贝叶斯法研究了斑腿蝗科、剑角蝗科、斑翅蝗科、网翅蝗科和槌角蝗科5个科42种的系统发育关系，得到如下结果：（1）由所有网翅蝗亚科的物种与剑角蝗科绿洲蝗亚科和槌角蝗科的物种组成一个单系群；斑翅蝗科的物种组成一个单系群；网翅蝗科的竹蝗亚科的黄脊雷蓖蝗和青脊竹蝗聚在一起形成单系群；斑腿蝗科的长翅十字蝗和大斑外斑腿蝗亲缘关系较近，形成一个单系群；长角直斑腿蝗和等歧蔗蝗始终聚在一起，形成一个单系群。

Any of various small whitish homopterous insects of the family Aleyrodidae, having long wings and a white waxy body, often injurious to plants.

粉虱一种粉虱的白色同翅昆虫，有长翅及白色似蜡般的躯体，常常对植物造成损害

In the early rice and the late rice, the parasitism of S.

早稻白背飞虱长翅型和短翅型成虫被螯蜂、线虫和捻翅虫寄生的总寄生率分别为 1 3%和 34%，晚稻分别为 35%和 4 9%，短翅型的被寄生率显著高于长翅型，晚稻高于早稻。

During the selection process, the white eye with phenotype was the first selected goal, followed by the ebony body kept and the long winglet was discarded.

在选育过程中，以白眼作为第一目标选择性状，第二步选择黑檀体性状，淘汰长翅性状，最后提纯白眼黑檀体和小翅个体。

The indrect flight muscles in macropterous nymphs developed rapidly while those in the brachypterous were suppressed after this critical period.

分化发生之后，长翅型若虫的间接飞行肌正常发育，短翅型若虫间接飞行肌的发育则被抑制。

The cross section of the mesothoracic dorsal longitudinal muscle in macropterous adult was 29 times of that in brachypterous adult, while the cross section of the mesothoracic dorsal longitudinal muscle in the brachypterous was only doublled from the critical period to audlt.

长翅型成虫背纵肌的横切面面积大约是短翅型的29倍，而短翅型成虫的背纵肌横切面积仅为4龄第16小时时若虫的2倍左右。

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。

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。

By fitting the models of semivariogram of them and analyzing the patterns, it was found that the nugget range of macropterous SBPH and larval SBPH were approaching to that of spiders, as well as the range of structural intensity, but the nuggets of SBPH were not approaching to that of spiders, neither the structural intensity. The spatial pattern of larval SBPH and spiders were aggregation, but that of macropterous SBPH was random sometimes.

通过变差函数模型的拟合及空间格局的分析，得出灰飞虱长翅成虫、若虫与蜘蛛的变程范围相近，结构性强度的范围相近，但同一时间灰飞虱与蜘蛛的变程和结构性强度则均不尽相同；灰飞虱若虫与蜘蛛自始至终为聚集分布，但灰飞虱长翅成虫与蜘蛛的分布型则有差异，在某些时间为均匀分布。

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%。
