CALLISTEPHUS INSECT PROBLEMS
Leafhopper feeds on China Aster and carries aster yellows.
Aphids suck juices but are controlled by several
pesticides.
Black blister beetle feeds on flowers and foliage in the
middle of June.
Tarnished plant bug punctures the terminal shoot below the
flowers and injects a poison causing the flower to die.
Mites cause the plants to lose their good green color and
appear stippled. Heavy infestations develop noticeable
amounts of very fine webbing.
