氮肥对植物-植食性昆虫-天敌三级营养关系的影响
Impact of Nitrogen Fertilizer on Plant-Herbivore-Natural Enemy Tritrophic Interactions
摘要
Abstract
Tritrophic interactions among plant-herbivore-natural enemy are interdependent and co-evolution by food chain/net in ecosystems, and are often heavily shaped by bottom-up forces. Nitrogen fertilizer can exert significant influence on the tritrophic interactions through various mechanisms. Nitrogen availability can alter quality of the plant, then affect feeding preference, food consumption and utilization, development, survival, reproduction, population dynamic of herbivore and ecosystem, the effect even can extend to natural enemy. Nitrogen also affect direct and indirect defense of plants, influence natural enemy control efficiency through variation of plant structure, nutritional quality of plants, habitat, and volatile induction. The impact of nitrogen fertilizer on tritrophic interactions and potential importance to agricultural production were reviewed.关键词
