Ambrosia Beetle Facts
What kills the ambrosia beetle?
Permethrin and bifenthrin are two common pyrethroids used to reduce ambrosia beetle attacks. Systemic products such as imidacloprid are ineffective because the beetles do not feed on vascular plant tissue. Keep trees healthy and avoid any unnecessary tree stress (drought, injury, nutrition, etc.).

Males cannot fly and are used solely for mating purposes. Small galleries are produced inside infested trees are used for rearing symbiotic fungi, which granulate ambrosia beetles use as a food source.
What causes ambrosia beetles?
It is unknown what causes plant death; plant death may be caused by beetles girdling of the vascular tissue and/or by the action of pathogenic fungi introduced into the plant by the beetles. Ambrosia beetles breed in a wide range of hosts, mainly broadleaf woody plants, where they farm their symbiont fungi.
How do you keep ambrosia beetles away?
Remove and destroy severely infested trees to prevent the infestation from spreading. Sprays that contain pyrethroids are effective at preventing ambrosia beetles from entering a tree. Use the spray according to the label instructions when you know that there are ambrosia beetles in the area.
Where do ambrosia beetles live?
The highest diversity of ambrosia beetles is in the tropics. In the Paleotropical region, hundreds of species of Xyleborini and Platypodinae are the main agent initiating dead wood decomposition. In the Neotropics, Platypodinae and Xyleborini are joined by the scolytine tribe Cortylini.
What does a redbay ambrosia beetle look like?

What is ambrosia disease?
In these cases, the beetle alone is reported to cause significant damage on the host tree. In other situations, ambrosia beetleassociated damage relies on significant infestation by the insect and associated disease that is caused by moderately virulent symbionts (89,120,161).
What other plants are affected by the ambrosia beetle?
Some highly susceptible tree species include Styrax, dogwood, redbud, maple, ornamental flowering cherry, Japanese maple,crapemyrtle, pecan, peach, apple, plum, persimmon, goldenrain tree, sweetgum, Shumard oak, Chinese elm, magnolia, fig, Rhododendron and azalea.
What are the ambrosia beetle host species?
Camptocerus species (Scolytini) are specialized to Protium species in the Neotropics. Even more host-specific are the few ambrosia beetle species that attack live trees. For example, Austroplatypus incompertus, an eusocial platypodine, colonizes only live Eucalyptus trees (Smith et al., 2009).
Are ambrosia beetles invasive?
Gallery (with pupae and fungus) of ambrosia beetle. This invasive pest is a problem in many southern states, causing damage to fruit trees and ornamentals. There are several different species of tiny insects called ambrosia beetles.

Xyloterini. A bark beetle is one of about 6,000 species in 247 genera of beetles in the subfamily Scolytinae.
How does wood borer spread?
The larvae produce large amounts of bore-dust (or frass) containing cylindrical pellets. Sometimes this is visible in the ‘blistered’ appearance of the surface wood. Longhorn beetles will fly freely in hot, sunny weather which enables them to spread an infestation from one building to the next.

Where do redbay ambrosia beetle come from?
Biology. The redbay ambrosia beetle is believed to originate from Asia or southeast Asia. Males are haploid, smaller in size, and flightless.
What nutritional benefits do symbiotic fungi provide to ambrosia beetles?
3.2. 1 Symbionts modulate induced plant defences in Coleoptera. Bark and ambrosia beetles farm mutualistic fungi to feed both larvae and adults. These species attack conifers, which prevent insect colonization using resins enriched with toxic compounds like terpenes.
How do you get rid of redbay ambrosia beetles?
Redbay trees emit a chemical when infected by the fungus that causes laurel wilt. That chemical, methyl salicylate, works to repel the Redbay Ambrosia Beetle.
Where are redbay ambrosia beetle found?
This beetle/fungus combination now ranges from the southern part of North Carolina to the southern tip of Florida, decimating mature redbay trees in its path. In addition to redbay trees, they also threaten other members of the laurel family including sassafras (Sassafras albidum) and avocado (Persea americana).
How was the redbay ambrosia beetle introduced?
Spread: One major way that the redbay ambrosia beetle and laurel wilt fungus will spread quickly out of the southeast USA is via the movement of wood that is infested with beetles (larvae or adults). Consequently, redbay and other host woody forest species from infested areas should not be moved or sold as firewood.

Do bark beetles fly?
Do bark beetles fly? Yes. The literature has documented pine bark beetles flying up to 2 miles and there is also evidence that beetles may occasionally disperse long distances via wind currents. In general, they appear to colonize suitable host trees nearby rather than fly long distances.
Do bark beetles live in dead trees?
There are 600 different species of bark beetles in the United States. Several species, such as the mountain pine beetle (Dendroctonus ponderosae), attack and kill live trees. Most species of bark beetles live in dead, weakened, or dying hosts. Bark beetles are important disturbance agents in western coniferous forests.
Do beetles carry disease?
Plantfeeding beetles are now recognized to transmit at least 40 viruses in six different virus genera. Yet in discussions of insect transmission of plant viruses, beetles usually warrant only a passing reference as the elegance of virusaphid interactions quickly advances to prominence in reviews.
