Integration of biological control with other management tactics such as prescribed burning is often important for successful invasive weed control. A critical step in this integration is determining whether the agent can colonize postburn growth of the weed. Here, we investigated postburn colonization by biological control agents on regrowth of the invasive vine Lygodium microphyllum (Cav.) R. Br. (Lygodiaceae, Old World climbing fern) in Florida. We monitored regrowth and subsequent colonization of two agents already established in Florida-the gall-inducing mite Floracarus perrepae Knihinicki and Boczek (Acariformes: Eriophyidae) and the foliage-feeding moth Neomusotima conspurcatalis Warren (Lepidoptera: Crambidae)-following three prescribed burns. We provide the first report of natural colonization by the F. perrepae mite and N. conspurcatalis moth on postburn L. microphyllum regrowth, and this colonization typically began 5-9 mo postburn. Furthermore, we report that L. microphyllum can recover to prefire levels of percent cover in as little as 5 mo. Our findings indicate that biological control of L. microphyllum has the potential to be integrated with prescribed burns.

生物控制剂对入侵小叶海参（Lygodiaceae）火灾后再生的定植

将生物控制与其他管理策略（例如规定的燃烧）相结合对于成功的侵入性杂草控制通常很重要。这种整合的一个关键步骤是确定该药剂是否可以定植杂草的烧伤后生长。在这里，我们研究了生物控制剂对侵入性藤本植物小叶海参 (Cav.) R. Br. 再生的烧伤后定植。（Lygodiaceae，旧世界攀缘蕨类植物）在佛罗里达州。我们监测了佛罗里达州已经建立的两种药剂的再生和随后的定植 - 诱导瘿螨 Floracarus perrepae Knihinicki 和 Boczek（Acariformes：Eriophyidae）和食叶蛾 Neomusotima conspurcatalis Warren（鳞翅目：Cramidae）-遵循三种规定的烧伤。我们提供了 F. perrepae 螨和 N. 自然定殖的第一份报告。conspurcatalis 蛾在烧伤后 L. microphyllum 再生，这种定植通常在烧伤后 5-9 个月开始。此外，我们报告说 L. microphyllum 可以在短短 5 个月内恢复到火灾前的覆盖百分比水平。我们的研究结果表明，L. microphyllum 的生物控制有可能与规定的烧伤相结合。
