Page 78 - ... when fertilization takes place, as the essential oil that gives the insecticide qualities reaches, at this time, its greatest development. When the blossoming has ceased the stalks may be cut within about four inches from the ground and utilized, being ground and mixed with the flowers in the proportion of onethird of their weight. Great care must be taken not to expose the flowers to moisture, or the rays of the sun, or still less to artificial heat. They should be dried under cover and hermetically...
Page 174 - ... larvae were counted under one plant, which was not a very large one. After feeding for from ten to fifteen days, having suffered three molts, the larva commences to spin its cocoon. The cocoon is oval, pale yellow in color, and is composed of coarse threads forming an irregular net-work, as shown at /and g in the figure. In the breeding-cages (during the winter of 1881-'82) it was usually spun between two or more leaves or leaf-stalks and attached to them. This is in accord with what is recorded...
Page 90 - Worm moth consigns her eggs in wild or tame grass or in grain is along the inner base of the terminal blades where they are yet doubled, or between the stalk and its surrounding sheath. They are by no means strictly confined to these situations, as is shown by the fact that we have known the moths in breeding cages to oviposit in crevices on the side of sward which had been cut with a knife, or even between the roots.
Page 223 - finest kind is that obtained by exudation and subsequent inspissation in the sun. The plan of bruising and expressing the leaves and boiling down the juice yields an inferior article, as a large portion of the liquor is derived from the mucilaginous juice of the parenchyma. The worst plan is said to be that of boiling the leaves in water and evaporating the decoction. The...
Page 96 - ... it. Along the ditch or furrow on the side of the field to be protected, a space of from 3 to 5 feet might be thoroughly dusted (when the dew is on) with a mixture of Paris green and plaster, or flour, so that every worm which succeeds in crossing the ditch will be killed by feeding upon plants so treated. This mixture should be in the proportion of one part of pure Paris green to twenty-five or thirty parts of the other materials named. If used in...

Page 172 - Dr. Melsheimer did in some instances mix up European and American species. Our attention was first called to this insect by letter from Mr. LD Snook, of Barrington, Yates County, New York, in July, 1881, stating that great damage was being done to the clover on his farm. In the latter part of April he first noticed on a field of clover, here and there, small patches where the leaves were badly eaten. The damage increased rapidly in extent, and by the end of July the whole field (about seven acres)...
Page 199 - Numerous observations made by myself and by students in my laboratory* show the following to be the periods of the different stages of the Vine-Loving Pomace-Fly during the month of October. Duration of egg state, three to five days ; of larval state, three to five days, usually four ; of pupal state, three to five days also ; and the time which elapsed between, the emerging of the flies and the beginning of laying eggs, in some cases, was not more than two days. This rapidity of multiplication greatly...
Page 175 - The silk issues from the spinneret in a very perceptibly liquid condition, but soon hardens, and the thick threads forming the walls of the cocoon are coarse, tough, and strong. The length of the pupa state in late fall is about twenty-five days. As will perhaps have been gathered from the preceding, the principal damage is done by the insect after it arrives at the perfect or beetle state. The beetle is very voracious, and devours the leaves at a rapid rate, eating the flower heads and stalks and...
