 The fig blister mite [R.A.E., A, x, 2vS0] is thought to be a new species 

 and has been given the manuscript name of Erwphyes fici by H. E. 

 Ewing. The species attacking blackberry [loc. cit.] has been determined 

 as E. gracialis, Nalepa.

Poison against the Fruit-tree Leaf-roller. — Mthly. Bull. Cal. 



Dept. Agric, Sacramento, xi, no. 5-6, May-June 1922, p. 469. 



The addition of small amounts of glucose increases the efficacy of 



poison sprays for use against Tortrix {Ar chips) argyrospila (fruit-tree 



leaf-roller). The sprays tried were 7| and 15 lb. of neutral lead arsenate 



and 6 and 12 lb. of acid lead arsenate to a 200 U.S. gal. tank, with the 



addition of 2| U.S. gals, of corn s^Tup (glucose). 



The larvae were nearly all fully developed when the work was carried 

 out. The most rapid results were obtained, as was expected, with the 

 greater strength of acid lead arsenate, the killing effects of the other 

 strengths being more or less proportional to the amount of actual 

 arsenic in the mixture.
