SP290-Q-Boxwood Leafminer

Boxwoods were brought into the United States in the 1800s. With the introduction of this plant came the boxwood leafminer, Monarthropalpus flavus (=buxi) Schrank.

The boxwood leafminer is considered to be the most serious pest of boxwoods. It occurs from the Atlantic to the Pacific, wherever boxwoods grow. All varieties of the boxwoods are attacked; however, the slower-growing English varieties are less susceptible than the American varieties.
