CALIFORNIA FRUITS: HOW TO GROW THEM 



vaded by it. The first moths appear at some time after the blossom- 

 ing of the apple, and deposit their eggs on the young fruit or on 

 adjacent leaves. The young worm hatches in from seven to ten 

 days generally seeks the eye or calyx, and eats its way into the 

 fruit' and in twenty days its full growth is attained, and it goes out 

 through the side of the apple, and, by means of its spmnaret, 

 reaches the ground or some large branch. If landed oft the ground, 

 it usually seeks the trunk, which it ascends and soon finds a hiding 

 place under the loose bark, where it spins its cocoon, and in eight 

 or ten days comes forth a moth, ready to lay eggs anew. The egg 

 is laid all over the fruit and especially at a point where two fruits 

 touch. Usually we have in this State two broods, at least, but some- 

 times three, and, naturally, if unchecked, the increase from the first 

 to the last is enormous. The worms escaping from the fruit in the 

 fall hibernate as larvae under the loose bark of the tree, or in store- 

 houses, or in any available dry place. 



This insect is effectually controlled by spraying with lead arse- 

 nate. The times for spraying and number of applications differ in 

 the several apple regions of the State and county horticultural com- 

 missioners or farm advisors should be consulted. 



The Walnut Worm. This is the codlin moth which also attacks 

 apples and pears and is fought in the same way. It is also being 

 fought with a dust spray of lead arsenate. 



The Peach Worm. As already stated, the larva of the peach 

 moth, which early in the spring bores into the twigs, is sometimes 

 found later in the season in the flesh of the peach. Hence the im- 

 portance of saving the fruit by proper treatment of the hibernating 

 worms, which are killed as they emerge with lime-sulphur. 



The Diabrotica. A light green beetle with twelve spots on his 

 back (Diabrotica soror) is sometimes very injurious to early fruit, 

 by eating into it when ripe. The insect also eats leaves and blos- 

 soms. As it attacks the fruit just as it is ready to pick, it is im- 

 possible to apply any disagreeable or poisonous spray. Sometimes 

 the insects are driven away by dense smoke from fires in and around 

 the orchard. 



The Dried Fruit Worm. Dried fruit is often seriously injured 

 after packing, by a small worm, larva of a moth. The eggs are 

 deposited on the fruit either while drying or while in the packing- 

 house, or through the cloth of the sacks, or seams of the package. 

 The eggs may be killed on the fruit before packing, by dipping in 

 boiling water, and after that preventing the access of the moth. In- 

 fested fruit can also be treated by bisulphide vapor. 



ANTS AND YELLOW JACKETS 



These insects are often of serious trouble during fruit drying. 

 Ants are most effectually disposed of by slightly opening their holes 

 in the ground by thrusting down a crowbar and pouring in a couple 

 of ounces of carbon bisulphide and closing again with earth. Yellow
