Squash Stink-Bug (Anasa Tristis)

Large, dark brown bug hibernates as adult under rubbish. Female lays large brown eggs in patches on the leaves. The young are greenish, feed in colonies on under side of leaves, causing them to wilt and die.

Treatment

Trap adults in spring under boards laid on the ground. Destroy eggs by hands. Young can be killed with "Black Leaf 40" tobacco extract, one pint in one hundred gallons of water, adding four to five pounds of soap.

Stem-Borer (Melittia Satyriniformis)

Soft, white, grub-like larva which bores inside the stem and causes rot to develop, killing the vine.

Preventives

Plant early squashes as traps. As soon as the early crop is gathered, burn the vines to destroy eggs and larvae of the borer. Fall harrowing of infested fields will help to expose the pupaae to the elements. Cut out borers whenever found. After the vines have grown to some length, cover some of the joints with earth, so that a new root-system will develop to sustain the plant in case the main root is injured.
