食虫植物

Lepidoptera: Sphingidae on three Apocynaceae plant species ( Allamanda cathartica L., Catharanthus roseus L., and Thevetia peruviana Merr.).

为了评估此虫在三种植物上的生长情形，使用两种餵食分析方法。

Large cylindrical or flattened mostly tropical insects with long strong legs that feed on plants; walking sticks and leaf insects.

大型的柱状或平面的主要为热带的昆虫，长腿，以植物为食；竹节虫和叶虫。

It has good control effect, and its action mode has stomach poison, contact killing, antifeedant, fumigation and anesthetization.

发明人多年来对雷公藤根、茎、叶等植物组织用酸水提取法、乙醇提取法、氯仿热提甲醇沉淀法提取的浸提物进行了杀虫谱和杀虫效果的研究，发现雷公藤浸提物对众多农业害虫和园林树木害虫具有较好的防治效果，其对害虫的作用方式有胃毒作用、触杀作用、拒食作用、熏蒸作用、麻醉作用。

The results showed that no obvious contact toxicities against the 3rd instars larvae of Mythimna separata Walker were observed in all treatment, and only the extract of Euonymus japonicus exhibited notable stomach toxicity.

采用微量点滴法和载毒叶片饲喂法测定30种药用植物乙醇提取物对粘虫3龄幼虫的触杀、胃毒以及拒食活性，结果表明供试样品在50 mg﹒mL~(-1)浓度下，冬青卫矛Euonymus japonicus Thunb。

These unassignable animals include a large swiing predator called Anomalocaris and a soft-bodied animal called Wiwaxia which ate detritus or algae.

这些无分别的植物包括一种叫做奇虾的肉食植物和一种叫做威瓦亚虫的以岩屑和藻类为食的软体植物。

Research proved that plants sense--and react to--the presence of hungry, leaf-eating worms.

研究表明植物能感觉到饥饿的食叶虫的出现，也能够对此做出反应。

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。
