Página 46 - They were doubtless attracted by the odor of the preparation, the vinegar probably being an important agent in the matter. As flies feed only at night, the plates should be visited late every evening, the insects taken out, and the vessels replenished, as circumstances may require. I have tried the experiment with results equally satisfactory, and shall continue it until a better one is adopted.
Página 23 - Potato- worm, but it is far commoner on the closely allied tomato, the foliage of which it often clears off very completely in particular spots in a single night. Many persons are afraid to handle this worm, from an absurd idea that it has the power of stinging with the horn on its tail.
Página 53 - Btrips is to hold the outside ends of the arms in position; they also hold the front arms from closing.

Página 23 - We have handled hundreds of them with perfect impunity, and for the small sum of one cent, will undertake to insure the whole population of the United States against being stung by this insect, either with the conspicuous horn on its tail or with any hidden weapon that it may have concealed about its person. In fact, this dreadful looking horn is not peculiar to the...
Página 63 - Mr. Abbot tells us that this caterpillar is called in Virginia the hickoryhorned devil, and that when disturbed it draws up its head, shaking or striking it from side to side; which attitude gives it so formidable an aspect, that no one, he affirms, will venture to handle it, people in general dreading it as much as a rattlesnake.
Página 69 - When full fed, this larva attaches itself to the underside of the leaf, and in two days the skin bursts open on the back, and is worked down towards the tail ; when the pupa, at first pale, soon acquires a dull brownish color, the narrow whitish tail, which still adheres posteriorly, being significant of the species. See (Fig.
Página 66 - Little can be done in the way of extirpating these underground borers, when, as in the present instance, their presence is only indicated by the approaching death of the vine. Still, every vine-grower should make it a rule to search for them whenever he finds vines suddenly dying from any unknown cause, and ' upon finding such a borer should at once put an end to his existence. The beetle, which may often be found during the summer and fall months, and which not unfrequenlly rushes with heavy, noisy...
Página 46 - The experiment was continued for five or six days, distributing the plates over the entire lield, each days' success increasing;, until the numbers were reduced to two or three moths to each plate, when it was abandoned as being no longer worthy of the trouble. The crop that year was but very little injured by the boll-worm. The flies were eaught in their eagerness to feed upon the mixture by alighting into it and being unable to escape.
Página 26 - Figure 03, c, gives a somewhat magnified view of the pupa; and figure 63, b, shows the last few joints of the abdomen of the larva, magnified, and viewed, not in profile, but from above. The vent of the larva, as will be seen from this last figure, is situated ' on the upper surface of the last joint, so that its excrement naturally falls upon its back, and by successive discharges is pushed forward towards its head, till the whole upper surface of the insect is covered with it. In other insects,...
