The Redbay Ambrosia Beetle (Coleoptera: Ccurculionidae) Prefers Lauraceae in Its Native Range: Records from the Chinese National Insect Collection
Abstract
The redbay ambrosia beetle Xyleborus glabratus is unusual among ambrosia beetles because of its host specificity to Lauraceae, but it isn’t clear whether this is only a feature of the invasive American population. Our examination of the extensive collection in the Chinese Academy of Sciences suggests that Xyleborus glabratus strongly prefers Lauraceae also in its native Asia. These are also the first published records of the species from continental China, which highlights the value of entomological collections.
El escarabajo ambrosia Xyleborus glabratus es una especie insólita entre los escarabajos ambrosia, debido a su especificidad de hospederos de la familia Lauraceae, pero no está claro si esto es sólo una característica de esta población invasiva en los EE. UU. Nuestro examen de la extensa colección de la Academia de Ciencias de China sugiere que Xyleborus glabratusprefiere fuertemente hospederos de la familia Lauraceae también en su nativa Asia. Estos son también los primeros registros publicados de las especies en China continental, lo que destaca el valor de las colecciones entomológicas.
