种间杂交是研究植食性昆虫食性专化的遗传机制和霍尔丹定律生物学基础的主要途径。

We find a close conceptual connection between our theory that the diversification of phytophagous insects has been driven by oscillations in host range, and our personal interpretation of the most efficient way in which West-Eberhard's theory could account for plasticity-driven speciation.

作者找到一个作者的理论(植食性昆虫多样化是由寄主范围波动驱使)与作者对West-Eberhard的理论所作最有效率的解释，两者之间紧密的概念连结。

Whether sympatric speciation happens at all is a contentious issue, although rapid changes in the host preference of phytophagous insects has been observed.

Some insects neither phytophagous nor natural enemies can also play a role to certain degree. Diversity at the increase phase is the biggest, and if it is big enough,outbreaks of pine caterpillars can be suppressed,otherwise the outbreaks can occur.

松毛虫不同发生阶段中，上升阶段多样性最大，如此时多样性足够大，可有效地抑制松毛虫的暴发，否则松毛虫将在竞争中占优势地位，数量猛增，导致大发生。

The occurrence of Pieris rapae was significantly lighter in autumn cabbage fields than in spring cabbage fields, but the occurrence of Lipaphis erysimi was relatively grave, which rose steadily during the investigation period from October 9 to November 5, until the cabbage was ripe. In 13 species of predatory enemies there were 3 species of predatory insects and 10 species of spiders.

但菜青虫的发生量较春季明显较轻；菜蚜发生较重，在10月9日至11月5日的整个(来源：Ae8BC论文网www.abclunwen.com)调查过程中是稳步上升，由于该年秋季气温较高雨水较少有利于菜蚜的发生，直到甘蓝成熟其发生量均较大。

Screening Room is a strain, the effect of Health measurement room, processing room, and other forms of scientific research facilities, a strain breeding, toxicity screening, new product development, production process technology updates, transformation and application of international standardization, such as the ability to detect, keeping perennial DBM, Pieris rapae, Spodoptera litura, Culex, mosquitoes and other insects and training of a variety of microorganisms.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
