larvte in the spring reach maturity about July 7 to 10, from which time mature 

 larvse and pupse can be found until the latter part of July. By August 1 tlie 

 eggs of the second generation begin to appear, and by August 10 the young 

 larv£E are entering the fruit quite freely. Larv?e and pupse were found in 

 October, which, it is thought, may have been the third generation of moths, 

 above mentioned, or possibly stragglers from the second generation. Brief 

 reference is made to the control of the codling moth by the two forms of 

 arsenate of lead, a report upon which has been previously noted (E. S. R., 34, 

 p. 54S). The second spray should be made at the time the eggs are hatching 

 and the first brood of larvae are entering the fruit, probably three or four weeks 

 after the calyx or first spray, or about the first or second week in June. The 

 third application, usually given to check the larvse of the second brood, should 

 be made about six weeks after the second, or from July 25 to August 5. Where 

 a fourth spray is thought desirable for late-appearing larva;, it should be 

 applied about September 1. 



Data relating to a number of minor pests follow. Those thus mentioned are 

 the brown mite, which feeds primarily on clover, alfalfa, and peas, but also 

 occurs on fruit trees and in some instances causes considerable injury ; the 

 climbing or variegated cutworm which bores into the fruit ; the fruit-tree leaf- 

 roller, which, though present in the Hood River Valley for a number of years, 

 has only been a source of damage during the past two or three years; the 

 brown apple aphis which has been the source of considerable loss through its 

 injury to the fruit; the woolly apple aphis and the green apple aphis; the pear 

 slug; the San Jose scale and oyster shell scale; the peach and prune twig 

 miner ; and the apple leaf miner.
