The current leading biological control method of hemlock woolly adelgid is Sasajiscymnus tsugae, [originally called Pseudoscymnus tsugae]. [11] S. tsugae is a black lady beetle that is relatively host-specific, feeding only on three known aldegid species, including HWA.
The species is a biological control method for the hemlock woolly adelgid, Adelges tsugae, in North America, an invasive species that threatens the eastern hemlock, Tsuga canadensis and the Carolina hemlock, Tsuga caroliniana. [6]
L. nigrinus larva feeding in an A. tsugae ovisac. Laricobius nigrinus is a species of tooth-necked fungus beetle in the family Derodontidae. [1] [2] It is native to western North America, and it is being studied as a biological control agent for the hemlock woolly adelgid. [3]
Hemlock woolly adelgid spread in Erie County. Penn State Extension's Amber Stillwell organized an educational program to alert people about the insect last fall (https: ...
Join conservationists for a hands-on workshop at Cumming Nature Center to identify and survey the tree-killing insect, hemlock woolly adelgid.
In recent years, Finger Lakes residents already have been warned to be on the lookout for spotted lanternflies, Asian jumping earthworms, hemlock woolly adelgids, gypsy moths and other invasive ...
Some adelgids are destructive forest pests, and Laricobius beetles have been employed as agents of biological pest control to prey on them and reduce their populations. An example is Laricobius nigrinus, which is released in forests to control the hemlock woolly adelgid (Adelges tsugae). [3] As of 2014, there are about 23 species in the genus.
