Colorado Potato Beetle Control with Stink Bugs

The twospotted stink bug, Perillus bioculatus, is an good predator of Colorado potato beetle. Five consecutive releases of the bugs starting when eggs were present maintained plots in New Brunswick, Canada virtually free from the beetle. Spot releases against late larval instars resulted in poor control of potato beetles. Although the bugs disperse slowly between plants, they spread from the release plots over the rest of the experimental farm where they kept the plants free from any significant beetle damage. The releases were part of a three year project comparing IPM and conventional practices for the control of Colorado potato beetle in commercial potato production.
