Station for1912, page 253. * * * * * A MEMBER: Early in the spring I noticed something on thehickory trees swollen and bright red in color, so that the trees wereconspicuous from a distance. Later insects emerged which appeared to bethese little gnats that fly in swarms.... DR. BRITTON: From the description I am not able to say what itwas, but it was probably one of those gall flies, a great many speciesof which exist and which attack all kinds of plants. They do not, as arule, cause very serious damage, and I can not suggest any particularremedy. Did it interfere with the growth of the tree? A MEMBER: I noticed what seemed to be the same insect on thegrape vines. DR. MORRIS: I would call attention to one pest that is verydestructive to hazels; unless watched closely it will produce seriousinjury.
