The PI proposes a study of the influence of above and belowground herbivores on their host plants. Natural enemies may shape interactions between these herbivores and their hosts and this work will also investigate that aspect. PI Hunt will study weed biological control systems with an assemblage of specialized herbivorous insects and their host plants and natural enemies. In field experiments, root herbivores, leaf herbivores, or both will be released into caged plots of purple loosestrife dominated wetlands. The response of the plant community will be tracked and the PI will add a third trophic level interaction by looking at the effect of generalist predators on the herbivores.

该项目负责人提议研究地上和地下食草动物对其寄主植物的影响。天敌可能会影响这些食草动物与其宿主之间的相互作用，这项工作也将研究这方面。 PI Hunt 将研究由专门的食草昆虫及其寄主植物和天敌组成的杂草生物控制系统。在田间实验中，根食草动物、叶食草动物或两者都将被释放到以紫色珍珠菜为主的湿地的笼中。植物群落的反应将被跟踪，PI 将通过观察通才捕食者对食草动物的影响来添加第三个营养级相互作用。
