Forest Health Protection—Hemlock Woolly Adelgid | |
Pseudoscymnus tsugae The hemlock woolly adelgid faces a challenge in the form of the newly-discovered exotic adelgid predator, Pseudoscymnus tsugae sp. nov. Laboratory and preliminary field experiments indicate this coccinellid's potential to be one of the more promising biological control agents this decade. Tiny but voracious, both the larva and adult (shown here) attack all stages of the adelgid. Photo courtesy of: Carole Cheah. |
