Not illustrated. 1919 edition. Excerpt: ...the plum curculio does not breed as freely in apples as in stone fruits, still these are often seriously injured by its feeding and egg-laying punctures. A large proportion of those stung fall early in the season, while those that remain on the trees are usually rendered knotty and unmarketable. It has Fig. 219.--The plum curculio, curculio showing the egg posi side and dorsal view (x 5). tion. Enlarged. been recognized as a serious pest for over a century, and fully satisfactory means of control have not yet been devised. Control is particularly difficult because the greater part of the injury is caused by the adult, a long-lived, hard shelled beetle very difficult to poison because it feeds principally on the pulp of the fruit obtained through a small puncture in the skin. The insect passes the winter in the beetle stage, hidden away under leaves or other trash. Stone walls or hedges and adjoining wood lots furnish ideal hibernating quarters, as is shown by the greater injury to that part of orchards lying nearest to such retreats. In the spring about the time the buds open the beetles desert their winter quarters and appear on the trees. They are small, rough snout-beetles, about inch in length, mottled with black, gray and brownish, and there is a black shining hump on the middle of each wing cover (Fig. 219). The sharp-biting jaws are located at the tip of the snout, which hangs down something like the trunk of an elephant. The beetles attack the fruit as soon as it is set. Two kinds of punctures are made: those for feeding only and those for the reception of the egg. In feeding the beetle Fig. 221.--Plum curculio egg-crescents in young cuts a small, round plums, opening through the skin and then eats out a cavity in the pulp about I inch in...
