Anisopteromalus calandrae wasps are beneficial insects that are important natural enemies of Sitophilus weevils. The species is reared in commercial insectaries for release in grain bins. Because this wasp successfully withstands higher dosages of pesticide than the weevils it preys upon, it is extremely useful in storage systems known or suspected to contain residual pesticides.
