Eriosoma Lanigera, or the Wooly Apple-Tree Blight. These insects appropriate for their generic name two Greek words, signifying wool and body, the insect being partially enveloped in a cottony or wool-like secretion, furnished from its own body. The eggs are deposited in crotches or cracks of the branches or bark, often at or near the surface of the ground, or on new shoots springing from the parent tree.

From the well known nocturnal habits of moths, and the certainty of their being destroyed by a light, a cheap and effective mode of destroying them, shown in the annexed figure. It consists of a pan of viscid matter placed upon a stake, which is set in the field of cotton at suitable distances. A block of wood is placed in the center of the pan, upon which is placed a lighted glass lantern. The moths, being attracted by the light, dash against it and fall into the pan, and are thus destroyed before depositing their eggs upon the tender leaves of the growing plant.

The females deposit their eggs, which are small, oval, and black, on twigs and bark in the autumn; the insect is hatched out the next spring, and feeds upon the sap of the tree. The first broods are all females, which in a short time, without any intercourse with the males, give birth to living young by the process of gemmation. These also produce other young ones, which are all females as long as the summer lasts, and it is only in the autumn that males are produced, which, uniting with the females, become the parents of the eggs for the following spring brood, thus bearing living young all the summer, and laying eggs which can withstand the frosts of the winter in autumn for the following spring season, while the parent insects in winter are destroyed by the wet and cold weather and alternate freezing and thawing.
