Rearing techniques for butterfly species at risk

根据《濒危物种法》，斑点黑翅雀是加拿大的濒危物种。我们的研究填补了 ** 关键的知识空白，需要实现该物种在安大略，这是要 ** 确保现有的威胁集合种群和栖息地充分减轻，以允许长期 ** 持久性和扩展到无人居住的合适栖息地的整体恢复目标的物种。我们建议使用一个密切相关的 ** 物种具有类似的生活史，野生靛蓝Duskywing（Erynnis baptisiae），作为替代物种测试 ** 不同的圈养饲养技术和估计生存。我们的研究目标是：（1）确定Erynnis卵和幼虫发育的最佳条件，（2）制定圈养饲养方案，（3）测试不同的处理越冬个体。开发的方法也可以在未来用于其他风险授粉物种。在全球范围内，传粉者数量和物种多样性的减少 ** 引起了人们对全球粮食安全和经济发展潜在风险的关切。这项研究 ** 为加拿大的学术界和工业界合作提供了一个极好的机会，以实现保护和恢复受气候变化和其他人为因素威胁的濒危物种和经济上重要的传粉者的经济利益。

Mottled Duskywing are an endangered species in Canada under the Species at Risk Act. Our research fills in**critical knowledge gaps, required to achieve the overall recovery goal of the species in Ontario, which is to**ensure that existing threats to metapopulations and habitat are sufficiently mitigated to allow for the long-term**persistence and expansion of the species into unoccupied suitable habitats. We propose to use a closely-related**species with a similar life history, Wild Indigo Duskywing (Erynnis baptisiae), as a surrogate species to test**different captive rearing techniques and estimate survival. Our research objectives are to: (1) determine the**optimal conditions for Erynnis egg and larval development, (2) develop a captive rearing protocol, and (3) test**different treatments to overwinter individuals. Methods developed can also be used in the future for other**at-risk pollinator species. At the global scale, declines in pollinator populations and species diversity have**raised concerns regarding potential risks to global food security and economic development. The research**provides an excellent opportunity for academic and industry collaboration in Canada to realize the economic**benefits of protecting and recovering species at risk and economically important pollinators threatened by**climate change and other anthropogenic factors.**
