PEACH PESTS

and having a wing expanse of about 'j 

 inch. It is quite beautiful with its dark- 

 gray, fringed wings. They are very seldom 

 seen in the orchards by the fruit growers, 

 because of their small size, their close 

 resemblance to projections of the bark 

 and their habit of resting perfectly still 

 during the daytime. 



The Efig. — Eggs of this insect were first 

 found by Marlatt, who kept the moths in 

 confinement and found that they were 

 deposited above the bases of the petioles 

 of the leaves. Clarke found the eggs 

 of the first brood in the orchard in the 

 same location as described by Marlatt. 

 He found, however, that the eggs of the 

 second generation were laid not on the 

 twigs, but on the fruit and in the edge 

 of the stem-end depression ; the eggs of 

 the third generation were found in cracks 

 of the bark, or exposed on its surface 

 just above the crotches formed by the 

 new wood and on the old wood. 



The eggs are pearly white, changing 

 to a deep yellow before hatching. They 

 are quite conspicuous, being about 2/.5 

 of a millimeter (1/60 of an inch) in 

 length by 1/5 millimeter in breadth. 



These observations of the egg and egg- 

 laying habits of the insect made in Cal- 

 ifornia by Mr. Clarke, are very interest- 

 ing, as they are the first recorded from 

 studies made under the natural condi- 

 tions of the orchard. 



Remedies. — Experiments conducted by 

 the writer in Colorado during the sea- 

 sons of 1910 and 1911, and by Clarke in 

 California, indicate that commercial lime 

 and sulphur, used at the strentgh of 1 

 gallon to 10 of water, is an effective rem- 

 edy for this pest. We have used it suc- 

 cessfully both in the fall and spring. 

 Earlier experiments conducted in this 

 state by E. P. Taylor indicated that ar- 

 senate of lead used at the strength of 5 

 pounds of the paste to 50 gallons of wa- 

 ter, and applied when most of the blos- 

 som buds showed their pink tips, would 

 al.so result in their control.

Striped Peach Worm 



Gclechia confusella 

 The striped peach worm, recorded as 

 doing serious damage in Michigan. The 

 larva is described as "dirty white with, 

 six longitudinal, reddish-brown stripes, 

 and with a yellowish-brown head and 

 thorax. It wriggles violently when dis- 

 turbed. It binds together the leaves with 

 a web of fine silk, forming a nest of 

 loosely bound leaves in which several
