Dendroctonus frontalis, the southern pine beetle, [1] often shortened to simply SPB, is a species of bark beetle native to the forests of the southern United States, Mexico and Central America. [2] It has recently expanded its range to the northeastern United States , where it is considered an invasive species and has destroyed massive amounts ...
The southern pine beetle (Dendroctonus frontalis), a bark beetle, is a major threat to pine trees in the southeastern United States. Its reproductive cycle is controlled by varying ratios of certain natural chemicals, including verbenone. To reproduce, pine bark beetles aggregate in large numbers in their host pine trees.

[4] Chestnut blight is a fungus spread through wind dispersal and rain splatter; the blight traveled up to 50 miles in a year by natural means. [5] Insect pests, once they reach the adult phase, have the ability to disperse by flight.
