The costs of pheromone production

点击翻译按钮获取中文摘要

This project seeks to answer fundamental questions in sexual selection theory. Chemical communication plays a fundamental role in mate choice in most taxa, yet it is critically under-researched. Traditionally, the costs of pheromone production have been assumed to be low. How these ‘low-cost’ signals remain ‘honest’ remains a central question in evolutionary biology. This project intends to quantify the costs of pheromone production in two insect model systems with different modes of chemical communication, and to reveal the underlying physiological mechanisms that ensure signal honesty. This project expects to advance knowledge in the fields of chemical communication and insect immunology which may provide information useful to pest management.
