The rise of megafires and extreme fire behaviors poses a significant threat to insect populations, affecting their survival and postfire recolonization. Megafires threaten the entire insect communities by changing fire regimes and habitats. These fires are now burning non-fire-prone ecosystems, endangering non-fire-adapted insects and habitats. While implementing prescribed burn programs can reduce the chances of megafires from developing, some megafires will be unpreventable. Land managers can mitigate the fire impacts by creating refugia and promoting heterogeneity in burn severity through fire control measures. Last, these post-megafire landscapes can provide an opportunity to restore historical fire regimes through subsequent prescribed burn management. This will revitalize ecosystems, benefit insects, and reduce the likelihood of future megafires and subsequent insect loss.

面对火焰:昆虫对特大火灾的反应和不断变化的火灾状况

特大火灾和极端火灾行为的兴起对昆虫种群构成重大威胁,影响它们的生存和火灾后的重新定居。特大火灾通过改变火灾状况和栖息地来威胁整个昆虫群落。这些火灾现在正在燃烧不易着火的生态系统,危及不适应火灾的昆虫和栖息地。虽然实施规定的燃烧计划可以减少发生特大火灾的机会,但有些特大火灾是无法预防的。土地管理者可以通过创建避难所并通过消防措施促进燃烧严重程度的异质性来减轻火灾影响。最后,这些特大火灾后的景观可以提供一个机会,通过随后规定的燃烧管理来恢复历史火灾状况。这将重振生态系统,使昆虫受益,并减少未来发生特大火灾和随后昆虫损失的可能性。
