Hawaiʻi verbenone repellents for ambrosia beetles on healthy and diseased ʻōhiʻa 2022-2023
March 6, 2025
In this experiment at Waiākea Forest Reserve, we tested the efficacy of the semiochemical repellent, verbenone, in commercial SPLAT® Verb formulation, at protecting healthy and rapid ʻōhiʻa death-Ceratocystis infested ʻōhiʻa from ambrosia beetle colonization in the 2022 and 2023 field seasons. Data files include 1) raw beetle counts, 2) individual tree information, and 3) verbenone mean peak area.

The efficacy of the semiochemical repellent verbenone to reduce ambrosia beetle attack on healthy and Ceratocystis-infested ‘ōhiʻa trees
The Ceratocystis fungal disease complex, rapid ʻōhiʻa death (ROD), has killed over one million ʻōhiʻa (Metrosideros polymorpha), the keystone tree species of Hawaiʻi. The causal fungi can be spread by invasive ambrosia beetles (Coleoptera: Curculionidae) through fungal inoculum found on their bodies and in the frass they produce. Thus, there is a critical need to manage beetle attack on...
