Outbreaks of caterpillars have been recorded in some mangrove forests in Brazil and other countries. This study reports an infestation of Hyblaea puera caterpillars (Cramer, 1777) (Lepidoptera: Hyblaeidae) in the mangrove forest of the Mamanguape River, Paraíba State, Brazil. The attacks occurred between May and July 2020 and affected Avicennia germinans (L.) L. and Avicennia schaueriana Stapf & Leechm. ex Moldenke. During the caterpillar outbreak period, the foliar herbivory rate was > 50 % in both species. Throughout the distribution area of the species in the estuary, there was variation in the intensity of caterpillar infestation: from the absence of attack to the complete defoliation of the trees in mono-specific forests of A. germinans. The consequences of severe defoliation are briefly discussed, emphasizing mangrove conservation.

在巴西和其他国家/地区的一些红树林中已记录到毛毛虫的爆发。这项研究报道了巴西巴拉那巴州马曼瓜佩河的红树林中的小毛虫（Cymer，1777）（鳞翅目：Hyblaeidae）的侵扰。袭击发生在2020年5月至2020年7月之间，受影响的是Avicennia菌种（L.）L.和Avicennia schaueriana Stapf＆Leechm。前摩尔登克。在毛毛虫爆发期间，两个物种的叶食草率均> 50％。在河口物种的整个分布区域中，毛虫侵扰的强度存在变化：从没有受到攻击到在A.germinans的单特异性森林中树木完全脱叶。 简要讨论了严重落叶的后果，强调了红树林的保护。
