本实验还提取了褐飞虱若虫的总RNA，在反转录过程中，利用锚定的3'RACE方法，将所有的mRNA分成了三组，并反转录成cDNA。

Fragments from the 239th to the 944th nucleotide of the coding regions of all actin mRNAs were amplified with two actin specific primers. Fragments from the 239th nucleotide of the coding region to the end of actin mRNAs were also amplified The electrophoresis results were compared between the macropterous and brachypterous brown planthoppers.

利用两条肌动蛋白特异性引物，扩增出了肌动蛋白基因mRNA的编码区片段，另外，将肌动蛋白特异性引物作为上游引物，将与3'锚定反转录引物部分序列相同的引物作为下游引物，扩增出了从肌动蛋白基因mRNA的编码区第239号碱基到Poly尾的这段cDNA，并在翅型之间作了比较。

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。

The results indicated that triazophos increased the productivity of macropterous and ...

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。

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.
