Page 267 - This tribe of insects do not seem liable to the attacks of any of the cannibal races, either in the egg state or at any other stage. Our birds pay no attention to them, neither will the domestic fowls touch them. I have, as yet, found no way to get clear of them, but to pick them oft
Page 267 - The more common color of the dried cabinet specimens'is a dirty yellow, variegated as in the fignre with black and dark brown, and one of the most characteristic marks is a yellow V, sometimes looking more like a Y, or indicated by three simple dots on the scutel (the little triangular piece on the middle of the back behind the thorax).

Wandering Habits. — While engaged in feeding, the mites remain quiescent for a length of time varying from a few minutes to half an hour. They then move on a short distance and again become motionless. If disturbed they have a habit of erecting themselves upon the leaf, clinging to its surface only by the anal proleg. When dissatisfied with their surroundings, or when food becomes scarce, they wander...
Page 272 - ... roughened spot a plump white maggot is come upon, lying in a cavity it has made there for itself. At other times a large, eroded spot occurs, which is filled with wet and slimy dirt. On removing this dirt the surface is found to be rough and warty, with little grooves here and there, in each of which is a maggot. Sometimes, also, a maggot is seen with only its anterior end imbedded in the turnip, leaving a third or half the length of its body projecting out therefrom.
Page 513 - After treading in, the ground must be leveled by raking with a wooden or steel rake 'along the lines lengthways, not across. That done, it would be advantageous to use a roller over the land, so as to smooth the surface and further firm the seed, but this is not indispensable. When seeds are drilled in by machine the wheel presses down the soil on the seed, so that treading in with the feet is not necessary. After the seeds germinate so as to show the rows, which will be in from two to four weeks,...
Page 283 - The above formula gives three gallons of emulsion, and makes, when diluted, thirty gallons of wash. " The kerosene and soap mixture, especially when the latter is 'warmed, forms upon very moderate agitation, an apparent union ; but the mixture is not stable, and separates on standing or when cooled or diluted by the addition of wat°r. A proper emulsion of kerosene is obtained only upon violent agitation. It is formed, not gradually, but suddenly; in short, to use a familiar phrase, 'it comes
Page 278 - We have, therefore, the spectacle of an underground insect possessing the power of continued existence, even when confined to its subterranean retreats. It spreads in the wingless state from vine to vine, and from vineyard to vineyard, when these are adjacent, either through passages in the ground itself, or over the surface. At the same time it is able, in the winged condition, to migrate to much more distant points.
Page 329 - ... the first and second weeks of July. Of course it is desirable that the caterpillar be reared, so as to leave no doubt as to its identity with the moth in question. When the young trees and shrubs are found to be affected, they should be sprayed with Paris green or London purple in solution. THE COMMON LONGICORN PINE- BORER.
Page 91 - G as much as 14.37 per cent. The regular increase shows that the highest numbers must contain a large portion of endosperm. That this is the case the microscopic examination of the different tailings has shown. No. 1 is found to consist almost entirely of the outer coatings of the grain ; Nos. 2, 3, and 4 of the same mixed with a large proportion of endosperm, which is attached thereto, while in No. 6 it is...
