The Wheat Jointworm and Its Control (open access)

The Wheat Jointworm and Its Control

Revised edition. "The wheat jointworm is a very small grub which lives in stems of wheat, sucking the juices of the plant and causing a swelling in the stem. The egg from which it hatches is laid in the stem by an insect resembling a small black ant with wings. This insect attacks no other kind of plant. The injury which it does to wheat is very distinct from that caused by the Hessian fly, yet the depredations of these two insects are often confused by farmers. This paper is intended, therefore, to give a brief outline of the life history and the nature of the injury to the plant by the jointworm so that any farmer may readily recognize its work and be able to apply the measures of control herein recommended." -- p. 3-4
