- The CRB appears to be well established in a localized area on the Joint Base Pearl Harbor-Hickam.
- Hawaii Department of Agriculture and USDA are attempting to eradicate the beetle and have formed an incident command structure for responding.
- Surveys using a variety of traps paired with visual surveys of tree crowns and potential breeding areas within a 2 mile radius are underway to delineate the infestation. So far the beetle has only been detected on the base. Two dead beetles have been submitted to the program from Honolulu International Airport and Sand Island. Traps and tree surveys have not identified any populations in those areas.
- Eradication requires elimination of breeding sites where larvae feed and develop into adults. Every mulch pile within a two mile radius will need inspection and proper disposal if infested. Both the mulch and soil beneath require treatment since the larvae burrow deep into the ground to pupate before emerging as an adult beetle
- Two mulch piles and one rotting stump have been found that are active breeding sites. One mulch pile is very large: approximately 200 by 10 meters and more than 1 meter deep.
- The piles are located adjacent to a waterway that feeds into the ocean and near a landing strip, further complicating treatment options.
- Multiple strategies for disposing of the giant mulch piles are currently being pursued in cooperation with Joint Base Pearl Harbor-Hickam.
- Resources for carrying out the response are currently very limited. Multiple cooperating agencies have been mobilized to assist in the response.
- DOA is exploring the possibility of an emergency declaration from the governor to expedite the response.
- DOA is pursuing establishment of an Interim Rule to Quarantine regulated commodities
- Experts were flown in from Guam and the mainland this week to help assess the infestation, develop survey and control protocols, and train staff.
