SOME INSECTS INJURING-NUT TREES.
By W. E. Britton, State Entomologist, Connecticut.
Nut-bearing trees, like other kinds of trees, are attacked by insect pests. Some kinds are seriously injured by them; others scarcely at all. Some of these insects are borers in the trunk and branches; some devour the leaves; some feed inside the nuts and ruin them; some suck the sap from the stems and leaves.
I shall make no attempt in this paper to enumerate these pests. Time forbids. I shall only mention a few of the most obvious and most serious, and where possible, point out control measures.
The Walnut Caterpillar.
Datana integerrima G. & R.
During the month of August clusters of blackish caterpillars bearing white hairs, may be seen stripping the terminal branches of black walnut, butternut and hickory trees. This is called the walnut caterpillar, and it has been very abundant in Connecticut this season. Many small trees have been entirely stripped and large ones almost defoliated. There is only one brood each year in Connecticut, though two occur in the southern states, and the pupae winter in the ground. The adult is a reddish brown moth, having a wing-spread of about one and one-half inches. Clipping off the twigs and crushing the mass of caterpillars is perhaps the simplest control method on small trees. Spraying with lead arsenate will prevent defoliation.
