This mealy bug has made its presence felt in some portions of the State. It congregates in large numbers in portions of the tree, especially among the clusters of fruit. Treatment.—This insect is effectually destroyed by the ordi- nary washes used for scale, and by the ladybird Cryptolxmus montrouzieri, lately introduced. This ladybird is as effectual in destroying the mealy bug as the Vedalia and Novius are in devouring the cottony cushion Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
