Agricultural Experiment Station; Agriculture -- New York (State). The squash bug: a, adult; n, nymph side of the head is a long, slender beak, which is carried close to the body between the first two pairs of legs. This beak constitutes the mouth parts of the bug, and makes it, there- fore, a sucking insect. The beak has a deep groove on the upper side. Lying in this groove are four tiny, threadlike bodies. These have fine, sawlike teeth at their free ends, and are used by the insect to puncture a leaf or a stem. The juice of the plant is then drawn into the mouth of the insect. Story of its life.— The full-grown bugs hide in the fall beneath stones, boards, leaves, and any rubbish that they may find. In spring they come from their hiding places and begin their search for squash vines. When they find the plants, they soon commence to lay their brown eggs on the underside of the leaves, and sometimes on the upper side also. Occasionally the eggs are laid in regular rows, as shown in the illustration. In from eight to twelve days small green and black bugs hatch from the eggs. They are somewhat like the full-grown bugs, but without wings and with long legs. They are called nymphs, and each one has a beak with which it punctures the leaf and sucks out the juices. The nymphs grow and shed their skins five times before they become adults. More than a month is usually required for the bug to reach full size. Injury and control.— The squash bug punctures the leaf, sucks out the juice, and injects into the leaf a poison that kills the cells and causes the leaf to turn brown and wilt. It also carries a disease from one vine to an- other that may cause the death of the plants. Poisons will not kill the bugs, but early in the spring one shoiild keep a sharp lookout for the adult bugs and catch
