What's Being Discussed

The Hawaii Department of Agriculture and Biosecurity's Advisory Committee on Plants and Animals will meet on September 28, 2026 at 1:00 PM to discuss two main topics:

• A beneficial wasp as a pest control tool: The department is asking the committee to consider allowing a small wasp called Metaphycus macadamiae to be imported and released in Hawaii. This wasp would be used as a natural, biological control agent to fight a scale insect pest (Acanthococcus ironsidei) that attacks macadamia trees and other plants.
• Protecting Molokai from the Coconut Rhinoceros Beetle (CRB): Two community members, Kunani and Ipo Nihipali, have submitted a petition asking the state to create an emergency rule that would restrict materials capable of spreading CRB — such as soil, compost, wood chips, mulch, and plant matter — from being transported to Molokai from any other part of the state.

Decisions Expected

• A recommendation on whether to allow the wasp Metaphycus macadamiae onto Hawaii's restricted animals list and permit its import, possession, and field release.
• A finding on whether current rules are insufficient to stop CRB from spreading to Molokai, and a possible recommendation to adopt an emergency interim rule restricting the movement of CRB host materials to the island.

Who Should Pay Attention

• Macadamia farmers and agricultural workers affected by scale insect pests
• Molokai residents and businesses that transport plants, soil, or organic materials between islands
• Landscapers, nurseries, and contractors who move mulch, compost, or wood chips interisland
• Anyone concerned about invasive species and Hawaii's agricultural biosecurity
