Edith Marion Patch

Edith Marion Patch (July 27, 1876 – September 28, 1954) was an American professor of entomology, known for her research on aphids, a nature writer, and an author of children’s books about nature. In 1913 she was elected a Fellow of the American Association for the Advancement of Science (AAAS). She served as president of the Entomological Society of America (ESA) for one year from 1930 to 1931. In 2001 the Edith Marion Patch House, in Old Town, Maine, was added to the National Register of Historic Places. Quotes White masses looking like patches thick mold often occur on Apple apple trees, especially about pruning wounds or other scars the trunk and branches and upon water sprouts. Beneath this substance are colonies of rusty colored or purplish brown plantlice known as "wooly aphids" on account of the appearance of white covering which is, however, really composed of waxen filaments.The species is common in Maine on Crataegus hawthorn, Rowan mountain ash, and Baldwin (apple) Baldwin and some other List of apple cultivars varieties of apple.

Only two species of aphids of world-wide distribution are at present known which commonly attack the Potato potato plant in numbers sufficient to cause serious injury directly due to their feeding operations. These are are the "potato aphid" (Macrosiphum euphorbiae Macrosiphum solanifoli William Harris Ashmead Ashmead) and the "green peach aphid" or "spinach aphid" (Myzus persicae Johann Heinrich Sulzer Sulzer). A third species, apparently also of world-wide distribution, is often present on the potato, frequenting especially the underside of the lower leaves. This is the "buckthorn aphid" (Aphis nasturtii Aphis abbreviata Patch); which may, under certain conditions, sometimes cause infestations of a serious nature. All three of these species have been proved to be capable of spreading certain Potato#Pests and diseases potato diseases under experimental conditions; and there can be no logical doubt that they function in the same way in the field. Wherever potatoes are grown for seed purposes these three species of aphids may need to be reckoned with.

Egg-laying in this locality begins late in September and extends through October the time varying somewhat with different weather conditions.The eggs hatch in the spring and the aphids of the first generation, wingless forms called "stem-mothers", seek shelter between the folded parts of the growing leaves. The stem-mothers are slow in their development and are about a month in attaining full growth. On reaching maturity they do not lay eggs but produce their young viviparously.
