Plants are attacked by many kinds of insect pests, and quick detection is key to successful defense. A newly discovered way that plants can detect insect attack - sensing vibrations caused by insect chewing - is likely to be faster and more reliable than other known detection systems. This project has four goals. First, the new detection system will be studied in several kinds of plants and insect pests. Second, rapid screening methods for its action will be developed. Third, the features of the feeding vibration signal that are important to the detection will be characterized. Fourth, the kind of plant receptor likely to be detecting the feeding vibrations will be identified using mechanoreceptor mutants. This knowledge will provide targets for breeders to enhance plant resistance to insect pests. This project will train students and postdoctoral scholars for careers in science and communication with the public. It will also train teachers to incorporate more science into their classrooms. The world of plant-borne vibrations featured in this proposal is highly appealing to children and the public at large. By providing acoustic ecology kits and training to teachers, additional children will experience the excitement and rewards of science.

植物受到多种害虫的攻击，快速发现是成功防御的关键。一种新发现的植物探测昆虫攻击的方法——感应昆虫咀嚼引起的振动——可能比其他已知的探测系统更快、更可靠。这个项目有四个目标。首先，新的检测系统将在几种植物和害虫中进行研究。第二，开发其作用的快速筛选方法。第三，对进料振动信号中对检测有重要意义的特征进行表征。第四，利用机械感受器突变体来识别可能检测到摄食振动的植物受体类型。这些知识将为育种者提供提高植物抗虫害能力的目标。该项目将培养学生和博士后学者从事科学和公众传播事业。它还将培训教师将更多的科学知识融入课堂。在这个提案中，植物传播的振动世界对儿童和公众具有很大的吸引力。通过向教师提供声学生态学工具包和培训，更多的孩子将体验到科学的兴奋和回报。
