This study will investigate interactions between moths from the genus Hadena (the lychnis moth) and two divergent populations of the flowering plant species Silene latifolia (the white campion), an established research species that is also naturalized in the US. The S. latifolia populations vary extensively in floral, vegetative, and life-history traits, which are likely adaptations to dissimilar environments. The moths are nursery pollinators: adult moths pollinate, but the larvae parasitize fruit. Interactions including moth preferences, larval performance, and fruit damage will be examined in the natural European habitat. This research will suggest whether the balance between mutualism and parasitism varies among distinct environments with these nursery-pollinator and host-plant species. This is an interdisciplinary research project that combines ecology, evolution, and behavior to investigate the divergence of intricate biological interactions between natural populations. This project will offer extensive training in pollinator biology and ecological/evolutionary field techniques for young graduate and undergraduate researchers. These results will also provide empirical evidence of regional variation in plant-pollinator interactions. Additionally, this work will suggest whether conservation efforts should consider habitat-specific differences in the management of other pollinator species.

本研究将调查蛾属Hadena（Lychnis蛾）和开花植物物种宽叶蝇子草（白色坎皮翁），一个既定的研究物种，也是在美国归化的两个不同的人口之间的相互作用。 色葡萄阔叶树种群在花、营养和生活史特征上差异很大，这可能是对不同环境的适应。 蛾是苗圃授粉者：成虫授粉，但幼虫寄生在果实上。 相互作用，包括蛾的喜好，幼虫的性能，和水果的损害将在欧洲的自然栖息地进行检查。 这项研究将表明，互惠和寄生之间的平衡是否在不同的环境与这些苗圃授粉和寄主植物物种。这是一个跨学科的研究项目，结合生态学，进化和行为来研究自然种群之间复杂的生物相互作用的分歧。 该项目将为年轻的研究生和本科生研究人员提供授粉生物学和生态/进化领域技术的广泛培训。 这些结果也将提供经验证据的植物传粉相互作用的区域差异。 此外，这项工作将建议保护工作是否应该考虑其他传粉物种的管理栖息地的具体差异。
