Among bark and ambrosia beetle pests that disperse various fungi, the degree to which the beetle and its symbiont are each responsible for causing host damage varies from system to system – for example, Harringtonia lauricola represents a true pathogen of Lauraceae vectored by Xyleborus glabratus, but others merely facilitate the mass ...
The MSU HISL database contains a worldwide species list of Xyleborini, a major group of ambrosia beetles, from the Catalog of Scolytidae and Platypodidae of S.L. Wood and D.E.

It has been shown that the beetle is attracted to the smell of this fungus, which may concentrate attacks on specific trees. The beetle can infest branches as small as 1.5 cm (0.6 in) across and trunks 2.5 to 6 cm (1.0 to 2.4 in) in diameter. [5] This beetle is polyphagous, infesting many species of host trees. [7]

Different from highly diverse types in bark and ambrosia beetles, woodwasps only have a pair of mycangia on the top of their ovipositor. Then when females deposit their eggs inside the host plant, they inject the symbiotic fungi from mycangia and phytotoxic mucus from another reservoir-like structure.
