Project Description:
(Up to 250 words)
The Refuge has developed a consistent method of mass rearing the Gallerucella beetles that can easily be accomplished by school groups or other volunteers. The students set up an insectory, collect adult beetles from an infested site and allow them to multiply in the cages. The Montessori School in La Crescent , Minnesota has taken on the project and incorporated it into one of their learning units. Students learn math, science, and other subjects while contributing valuable efforts to invasive plant control
