The Cherry is affected by a number of the insects already considered (n connection with other fruit-trees.

In addition to these formidable enemies attention may be drawn to The Cherry Aphis {Myeus cerasi). This insect differs from most of the plant-lice in beinjf black instead of the usual preen color. It often appears on the leaves at the ends of the boughs in enormous numbers, causing the leaves to curl up and arresting further growth. The structure and habits of this species are similar to those of the Apple Aphis; it passes the winter in the egg state on the Iwies of the tree. The remedies already mentioned are effective in this case also, and should be applied as soon as the first colonies are noticed. Usually the presence of the insect is not observed until it has become vc-y numerous and the terminal leaves all over the trees are affected. Lady-bird oeetlcs (Fig. 44) and Aphis-lions (Figs. 45, 46) are usually to be seen feeding voraciously on the plant-lice and assisting very materially in the reduction of their numbers. Fig. 44.

This fungus attacks the leaves of the Cherry, particularly the young ones; also the tender shoots. It appears on the leaves in small white patches, which soon spread and run into each other, forming a thin white felt, which in some cases may cover the entire surface of t
