Asian Ambrosia Beetle

The Asian ambrosia beetle is a small, but deadly-to-trees insect, and it has the potential to be a major pest in the nursery industry all across the south. It has a wide host range of trees, mainly infesting small diameter, smooth bark sections of trees. Peach, pecan and plum orchards have been attacked, as well as nursery tree stock.

The beetles bore into the trunk, leaving tell-tale fragile spines of frass and sawdust sticking out of trunks like toothpicks. The beetles cultivate a fungus (ambrosia) upon which the larval brood feed. Infested trees usually quickly die.

Thess pages provides information on the beetle, including records of past trap catches, news releases, and other related information.

Growers can monitor Asian ambrosia beetle activity weekly as indicated by trap catches at a Smith County tree nursery by following the 1999 trap counts link below. Growers would be wise to monitor activity in their own nursery using simple water traps (see How to make an Asian ambrosia beetle trap). Control measures can be implemented as numbers of beetles peak based on trap catches.
