The facility will help expand the department's citrus germplasm introduction program, which provides a safe way to introduce new citrus cultivars to the state, according to a news release.
The 20,000-square-foot facility will significantly increase production capacity to more than 20 varieties annually.
The LaCrosse facility comes four months after the expansion at the state's Dundee Biological Control Laboratory, which is helping rear beneficial insects.
The Dundee facility is producing a minute wasp—Tamarixia radiata—that parasitizes Asian citrus psyllid young and adults.
One female wasp can kill up to 500 psyllids.
