FRUITS.--The insects that reduce our annual fruit crop attack every portion of the tree and its product. The woolly aphis attacks the roots of the fruit tree, the trunk and limbs are preyed upon by millions of scale insects and borers, the leaves are devastated by the all-devouring leaf worms, canker worms and tent caterpillars, while the fruit itself is attacked by the codling moth, curculio and apple maggot. To destroy fruit is to take money out of the farmer's pocket, and to attack and injure the tree is like undermining his house itself. By an annual expenditure of about $8,250,000 in cash for spraying apple trees, the destructiveness of the codling moth and curculio have been greatly reduced, but that money is itself a cash loss. Add to this the $12,000,000 of actual shrinkage in the apple crop, and the total annual loss to our apple-growers due to the codling moth and curculio is about $20,000,000. In the high price of apples, a part of this loss falls upon the consumer. In 1889 Professor Forbes calculated that the annual loss to the fruit-growers of Illinois from insect ravages was $2,375,000. In 1892, insects caused to Nebraska apple-growers a loss computed at $2,000,000 and, in 1897, New York farmers lost $2,500,000 from that cause. "In many sections of the Pacific Northwest the loss was from fifty to seventy-five per cent." (Yearbook, page 470.) FORESTS.--"The annual losses occasioned by insect pests to forests and forest products (in the United States) have been estimated by Dr. A.D. Hopkins, special agent in charge of forest insect investigations, at not less than $100,000,000.... It covers both the loss from insect damages to standing timber, and to the crude and manufactured forest products. The annual loss to growing timber is conservatively placed at $70,000,000." [Illustration: THE GYPSY MOTH, (_Portheria dispar_) Very Destructive to the Finest Shade Trees] There are other insect damages that we will not pause to enumerate here. They relate to cattle, horses, sheep and stored grain products of many kinds. Even cured tobacco has its pest, a minute insect known as the cigarette beetle, now widespread in America and "frequently the cause of very heavy losses." The millions of the insect world are upon us. Their cost to us has been summed up by Mr. Marlatt in the table that appears below. * * * * * ANNUAL VALUES OF FARM PRODUCTS, AND LOSSES CHARGEABLE TO INSECT PESTS. _Official Report in the Yearbook of the Department of Agriculture, 1904_. % OF PRODUCT VALUE LOSS AMOUNT OF LOSS
