INSECTS INFESTING THE PEACH TRRE. 129 



the buds is caused by the boring of the larva of A. lineatella, 

 but will not say positivel}^ that such is the case. It is also 

 reported as a destructive pest to the stravi^berry, by eating chan- 

 nels through the crown of the plant, and also burrowing into 

 the runners. 



Since writing the above, I have reared a number of the 

 perfect insects. The larva leaves the fruit to pass its tran- 

 formations. When it selects a place it spins a few threads, 

 then changes to pupa. It remains in the pupa state from 

 seven to ten days, according to the temperature. 



This season (1888), specimens of plums, prunes and necta- 

 rines have been received infested by the larva of this moth. 



Peaches received in this city (Sacramento) in July last, had 

 at least forty per cent, infested by this pest. The moth 

 deposits the egg on the fruit, generally near the stem. 



Remedies. — See No. 67, and use Nos. 5 or 7 as spray. For 

 strawberries, see No. 68.

 resents one inch divided into lines and fractions thereof.] 



[Living singly in a nest of newly-expanded leaves on peach 

 trees ; a pale-green worm, Avith two Avhite lines along the back,

This leaf-roller assumes the pupa state in its nest. The 

 fore-wings of the perfect moth expand about eight lines, and 

 are of a yellowish color, varied with black, and marked with 

 white spots.
