378 INSECTS INJURIOUS TO VEGETATION. 



to the ravages of the leaf-rollers and bud-moths, that infest 

 many of our fruit-trees and flowering shrubs, could be dis- 

 covered. 



Apricot, peach, and plum trees, when trained against walls 

 in the open air, are said to suffer very much sometimes from 

 the attacks of insects whose habits resemble those of the eye- 

 spotted Penthina. But, as I have not yet seen them in the 

 moth state, I cannot say whether they are of the same species 

 as the bud-moth above named. Perhaps they are identical 

 with the apricot-bud caterpillars (Ditula angustiorana) of Eu- 

 rope, the depredations of which have been described by Mr. 

 West-wood in the fourteenth volume of the " Gardener's Mag- 

 azine." Besides picking off" the curled and confined clusters 

 of leaves, when practicable, I would recommend thoroughly 

 drenching the trees with Mr. Haggerston's remedy, a pound of 

 oil-soap in from seven to ten gallons of water, in the hope that 

 some of the mixture might penetrate the injured buds and 

 leaves, and destroy the caterpillars concealed therein. A mix- 

 ture of one gallon of the liquor expressed by tobacconists from 

 tobacco, with five gallons of water, has been used to the same 

 intent. 



Roses are infested with several kinds of caterpillars belong- 

 ing to this tribe. Mr. Westwood has described one of them, 

 and mentions others that are found in Europe, in the thir- 

 teenth volume of the " Gardener's Magazine." Similar species 

 are not uncommon in this country. Some of these spoilers 

 fasten upon the leaves, and roll them up, or stick them together, 

 to serve them for food and shelter; while others lurk unseen 

 in the flower-buds, and canker them to the heart, before they 

 can spread their lovely petals to the sun, and breathe out their 

 fragrance to the air. A particular description of each of these 

 insects would occupy too much space here ; and I can only 

 add that the worm in the bud is to be destroyed only by hand. 



Pine and fir trees are also injured by some of the Tortrices, 

 that pierce the tender shoots and terminal buds. The seat of 

 their depredations becomes known by the oozing of the resin 

 and by the withering of the bud or shoot. The latter com- 

 monly dies in consequence of the injury, the upward growth
