The California Citrus Quality Council has scheduled a workshop on the Fuller rose beetle
The two-hour workshop, 1 p.m., June 17, at the Visalia Convention Center, will address the pest’s effect on exports and its control.
As its name implies, the beetle is more of a pest of roses than citrus, according to the University of California Integrated Pest Management website.
Where it causes headaches is with citrus exports to countries, such as Korea and Thailand, that don’t have the pest and have enacted quarantines against it.
Adults rarely make it into packing boxes. But if inspectors in importing countries discover eggs under the fruit calyx, or button, they may require fumigation or reject the load, depending on the country.
At one time, Japan also had a Fuller rose beetle quarantine but dropped it once the pest was found in that country.
Female beetles lay eggs on fruit, especially under the calyx, as well as in cracks or tree crevasses.
Because they’re difficult to remove from the fruit, the goal is to reduce the number of adults before they can lay them.
Adults can be controlled using an integrated program that includes monitoring groves, skirting trees, trunk treatments, foliar sprays and biological control.
