INJURIOUS INSECTS.

three-fourths of an inch long. These larvae either go into the 

 earth, under leaves, or remain attached to the bushes, and spin 

 a cocoon of brownish silk. The larvae will be found at work 

 till in July, as there are two broods each season. They remain 

 as pupae till the following spring, when the flies come forth to 

 repeat the round of mischief. 



REMEDIES. Prevention being universally conceded to be bet- 

 ter than cure, all should be certain not to import these insects 

 in procuring the plants. As 

 the cocoons are hid in spring 

 among the roots, these should 

 be carefully washed and the 

 material washed off and 

 burned. The absence of 

 such precautionary measures 

 accounts for the rapid spread 

 of these pests. The leaves 

 when first worked on are 

 perforated with small holes 

 (Fig. 37). As there are 

 comparatively few, the eggs 

 being so compactly placed that but few leaves receive them, they 

 can be gathered and burned. But if we have failed, either 

 through ignorance or neglect, to destroy these destroyers till 

 they become scattered over the bushes, we still can offer effec- 

 tual battle. White hellebore, dusted upon the vine in the same 

 manner that we would recommend for applying the Paris green 

 mixture on the potato, is sure destruction to these " worms." 

 This is the best applied when there is little or no wind ; and, 

 though poisonous, is entirely safe if used cautiously. If it is 

 preferred, as in most cases it doubtless will be, the hellebore 

 may be mixed with water and applied with a sprinkler, in which 

 case we are independent of wind, and can not inhale it. An 

 ounce to a pail of water is sufficient. As it costs^ but forty 

 cents per pound, it will be seen that it is not expensive.
