The species of ambrosia beetle are serious pests infesting woody ornamental, fruit, and nut trees. They attack both healthy and stressed trees. But the trees suffering from stress are the source of their attraction. The damaged barks or trunks of trees are often the entry point of Ambrosia Beetles. So, you should reduce the stress associated with trees to prevent the spread of Ambrosia Beetles. Go for a regular tree health assessment to identify all stressors and vulnerabilities your trees are going through.

About Ambrosia Beetle

Ambrosia beetles are small insects, only 2 to 3 millimeters in length, capable of devastating over 100 species of deciduous trees throughout California. Although they were first introduced into the Southeastern United States, the spread of the Ambrosia beetles is popular throughout the country.

Host plants may contain one to hundreds of species of Ambrosia beetles. When the female beetles excavate their galleries, they will produce strands of boring dust. Hence, the symptoms of a Wood Boring Insect infestation and damage of Ambrosia Beetle are perplexing.

However, these strands are quite fragile. So they break up easily due to wind, rain, and storms. You can notice the pencil-lead sized holes in these strands.

The damage to the infected plants and trees initiate when female beetles form tunnels. They will introduce the fungus to the wood of the host trees and plants. But they are rarely seen as they are mostly hidden inside the trunk until the infestation is serious. Also, they invite pathogenic fungi like Fusarium Wilt. So, a professional Ambrosia beetle removal treatment is crucial.

Symptoms Of Ambrosia Beetle

  • Wilted foliage and strands of boring dust protruding from small holes
  • 2mm round entrance holes in trunks of young trees
  • Holes of 1 to 2.5 inch diameter in branches
  • Blackening of the tissue surrounding the entry hole
  • Large amounts of resin may also exhibit gummosis or oozing sap at the entrance holes
  • Toothpick-like frass tubes sticking out of the tree
  • Saw dust frass around the base of your tree
  • Stunting, delayed leaf emergence in spring, and premature defoliation
  • Fungal staining in infected wood
  • The surface damage is similar to Shot Hole Borer
  • Terminal dieback

Female beetles bore into the trunks and branches of young and matured trees of your landscape. They inoculate trees with ambrosia fungus, which can block xylem vessels. Also, they will interfere with vascular transport.

The use of insecticides must be tailored to infected tree species. Seek professional assistance to control Ambrosia beetles with precise treatment. They will remove the actual stress, which invites infestation and disease.

Severe infestation may have many entry points. So, professionals inspect all infected trees and offer trunk and soil injections to block further growth. They will exercise caution when using fungicides around trees infested by Wood Boring Insects, Shot Hole Borers, and Ambrosia Beetles.

Frequently Asked Questions

Using ethanol baited traps and keeping an eye out for ambrosia beetles in late winter and early spring is a great Ambrosia Beetle Control. You can call professionals to begin preventative treatments once you notice or suspect the attack.

Yes, ofcourse. Plants or plant parts that are heavily infested should be removed and destroyed. Large producers may want to wait 3-4 weeks after trees are infected before removing them to focus and eradicate the most insects while sparing some healthy trees.

Pyrethroid pesticides can help preserve trees by preventing granulate ambrosia beetles from excavating galleries with preventative sprays. To protect trees from this pest, the timing of prophylactic insecticide applications is critical. Sprays should be used when beetles have been discovered in monitoring traps.

If you observe toothpick-like frass tubes poking out of your tree, it’s a dead giveaway that it’s infested with the Ambrosia Beetle. However, seeing this is uncommon because the “sawdust” is weak and quickly blown off the trunk. So, if you observe sawdust frass around the base of your tree, that’s a stronger indicator.
