Page 64 - ... writers of eminence, and others have a horticultural editor. Among all the periodicals, however, there is none more absolutely necessary to the gardener and farmer than the American Entomologist, published at St. Louis, Mo., and edited conjointly by the entomologists of that State and of Illinois. From the very practical pages of this journal we may gather hints of the greatest value. This paper is the more valuable and essential to us from the fact that it is the...
Page 22 - They possess the additional bad habit of gnawing into the stems of the clusters of the grapes, which either wilt or drop off. The eggs, which are 0.05 inch in diameter, perfectly round, and of a uniform delicate yellowish-green color, hatch Fig. 44. — Ampelophaga myron Cram., caterpillar. After Riley. into pale green worms with long and straight horns at the tails. After feeding from four to five weeks they reach their full size, and the horns look now comparatively short, with a posterior curve....
Page 41 - After the first excitement produced by the sudden heat was over, they remained as if wishing to " cool off" before commencing work again. A few did not recover from the application, but most of them were soon as active as ever. Now what I would suggest is this, that where hellebore cannot be at once procured, no time should be lost in applying the hot water, and when once on the ground the creatures may have the life trodden out of them by the foot, or beaten out with the spade or some other implement....
Page 24 - It is one of those remarkable and not easily explained facts, which often confront the student of Nature, that, while one of these Hog-caterpillars in its normal and healthy condition may be starved to death in two or three days, another, that is writhing with its body full of parasites will live without food for as many weeks. Indeed, I have known one to rest for three weeks without food in a semi-paralyzed condition, and after the parasitic flies had all escaped from their cocoons, it would rouse...
Page 66 - But when used with six to twelve parts, either of flour, ashes, plaster or slacked lime, it causes no serious injury to the foliage, and just as effectually kills the bugs. The varied success attending its use, as reported through our many agricultural papers, must be attributed to the difference in the quality of the drug. We hear many fears expressed that this poison may be washed •into the soil, absorbed by the rootlets, and thus poison the tubers; but persons who entertain such fears forget...
Page 48 - It is of a glass-green color, and very active, wriggling, jumping and jerking either way at every touch. The head and thoracic segments are marked as at figure 143, 2. If let alone these worms will soon defoliate a vine, and the best method of destroying them is by crushing suddenly within the leaf, with both hands. To prevent their appearance, however, requires far less trouble. The chrysalis is formed within the fold of the leaf, and by going over the vineyard in October, or any time before the...
Page 41 - ... caterpillars on half a leaf, must have materially diminished it. I am disposed to believe then that the death of most of these must have resulted from their imbibing or absorbing some of the liquid as soon as applied. Many of them showed symptoms of the violent cathartic action of the remedy, having a mass of soft exavia hanging to the extremity of their dead bodies.
Page 42 - I fed them they did not get through their work quite so quickly ; possibly they may have overfed themselves at first. While turning up the branches of some of my gooseberry bushes, I observed a number of whitish eggs on some of the leaves, arranged lengthwise in regular rows at short distances apart, on the principal veins or ribs of the leaf. Usually they were placed singly in the rows, but here and there double. These were the eggs of the currant worm, they were about one twentieth of an inch long,...
Page 23 - The full grown (Fig. 44) caterpillar is distinguished by having the third and fourth segments immensely swollen, while the first and second ones are quite small and retractile. According to Prof. Riley it is from this peculiar appearance of the fore part of the body, which strikingly suggests the fat cheeks and shoulders and small head of a blooded hog, that it is known as the "Hog-caterpillar.
Page 68 - But there are a few which always defy our efforts. The Tarnished Plant-bug belongs to this last class, for we are almost powerless before it from the fact that it breeds and abounds on such a great variety of plants and weeds, and that it flies so readily from one to the other. Its flight is, however, limited, and there can be no better prophylactic treatment than clean culture, for the principal damage is occasioned by the old bugs when they leave their winter quarters and congregate on the tender...
