Pest Watch: Biological Control of Scotch Broom

Jennifer Andreas ,
Online Only
Scotch broom is an invasive perennial shrub that displaces desirable plants in pastures, roadsides, and forestlands. Scotch broom is expensive to control and causes the loss of timber production and pasture use, costing the state millions of dollars every year. Two insects, a seed-feeding beetle, Bruchidius villosus, and a seed weevil, Exapion fuscirostre, are available as biocontrol agents to help control scotch broom.

This publication gives an overview of both insects and explains how they work as biocontrol agents and when to use them as part of a long-term weed management program.
