Like most insects, the female Ambrosia beetle is larger than the male. Ambrosia Beetles are typically dark reddish brown with a hunched-back appearance. The larvae are white, legless, C-shaped,and indistinguishable from other scolytids.
These Beetles are known to attack various trees and shrubs, including pecan, peach, plum, cherry, persimmon, oak, elm, sweet gum, magnolia, fig, buckeye, and sweet potato.
Adults and larvae bore into twigs, branches or small trunks of host plants. They then excavate a system of tunnels in the wood and introduce a symbiotic ambrosial fungus. This fungus then provides food for the beetle. This fungus however damages and clogs the xylem, ultimately killing all or part of the plant.
They usually display year-round activity, but most activity has been observed in March. The adults follow the typical pattern of arthropods. This pattern is that they mate, lay eggs, and start it all over again.
To get rid of an infestation, the plants should be removed and burned. Insecticides can reduce infestations, but can require multiple treatments and several weeks of time.
|Mutualism||Both organisms benefit|
|Commensalism||One organism benefits and the other organism isn't harmed|
|Parasitism||One organism benefits at the expense of the other organism|
|Competition||Neither organisms are benefited|
|Neutralism||Neither organisms are affected|
