. Biggle orchard book : fruit and orchard gleanings from bough to basket. Fruit-culture. Chapter VIII. SCALE PESTS: SAX JOSE, OYSTER SHELE, SCURFY, ETC. If hogs or cattle could multiply cs fast as scale lice, human beings would soon be crowded off the earth.—Dorothy Tucker. The most serious insect pest which confronts the orchardist of today, is undoubtedly the San Jose scale louse. It came to this country on nursery stock from Japan, and first took root in San Jose, Cal. It is sup- posed that it was brought east to New Jersey about twenty-five years ago, and it has spread until now it menaces the larger part of the United States. In a single season a female may become the pro- genitor of 1,608,040,200 individuals. The louse hides under a scale that is impervious to most insecticides. It attacks all orchard trees, roses, small fruit bushes, and many lawn shrubs and vines. The louse can crawl rap- idly, and is often carried by birds, insects and heavy winds. The insects are too small to be easily seen with the naked eye, but the scale can be seen. Bark of affected trees has a grayish or ashy appearance, in bad cases. It is the louse and not the scale that does the harm. (67). ADULT FEMALE SAN JOSE SCALE WITH YOUNG (ENLARGED, AS SEEN THROUGH A MAGNIFYING GLASS).
