Effects of Host Plant Water-Stress on Herbivorous Insects in Three Feeding Guilds

“水分胁迫”改善营养状况的理论 食草昆虫的植物质量，并导致爆发 得到了很多支持。 尽管研究报告显示， 表现为昆虫喂养水强调树叶其他人有 表明昆虫要么避免或生长不良的水压力 厂 看来直翅目和植食昆虫倾向于 受益于植物水分胁迫，但叶咀嚼和 但反对者则不然。 私家侦探将检验这一假设， 植物中的水分胁迫对植食性昆虫的影响取决于 昆虫的取食方式。 他将执行偏好， 控制饲养实验检查水的影响， 在寄主植物上对取食和产卵偏好的胁迫， 十种昆虫的生长、存活和繁殖力 在三个取食集团和四个昆虫订单。 大豆将 是自生理学和生物化学以来， 大豆在水分胁迫下是众所周知的。 这些实验将增进我们对 大豆与几种害虫的相互作用， 允许鉴定植物中水分胁迫的影响 对昆虫的影响取决于昆虫的取食方式。 这 这些信息将有助于解释昆虫的复杂反应， 水分胁迫的植物

The theory that "water-stress" improves the nutritional quality of plants for insect herbivores and leads to outbreaks has received much support. Although studies report improved performances for insects fed water-stressed foliage others have shown that insects either avoid or grow poorly on water-stressed plant. It appears that Orthoptera and sapfeeding insects tend to benefit from plant water-stress, but leaf chewers and skeletonizers do not. The P.I. Will test the hypothesis and that the effect of water-stress in plants on herbivorous insects depends on the feeding mode of the insect. He will perform preferences and controlled rearing experiments examine the effects of water- stress in the host plant on feeding and oviposition preference, growth, survival, and fecundity in ten insect species distributed among three feeding guilds and four insect orders. Soybeans will be the experiments since the physiology and biochemistry of soybean under water-stress is well known. These experiments will enhance our knowledge of the interactions of soybean with several of its insect pests, and allow the identification of the effects of water-stress in plants on insects herbivores depends on insect feeding mode. This information will help explain the complex responses of insects to water-stressed plants.
