to 30 gals. Nicotine gave the better results and no injury to 

 foliage resulted from its use. For larvae of codling moth [Cydia 

 jjomonella] on apples, dry arsenate of lead and arsenite of calcium 

 were tried to determine their comparative values. Three applications 

 of each substance combined with summer strength of lime-sulphur 

 were given ; lead arsenate proved to be the better poison. Pear 

 psylla [PsyUa pj/ri] caused considerable trouble in some localities, 

 and as spraying was not begun promptly, many orchards were badly 

 infested by mid-summer. Three mixtures were used as sprays : 

 kerosene emulsion, 40 per cent. ; nicotine 1 : 800 and soap ; and a 

 mixture consisting of 40 lb. stone Kme, 1 U.S. pint nicotine and 1 U.S. 

 gal. lime-sulphur to 100 U.S. gallons. These mixtures were applied in 

 early August ; very little difference in effectiveness was observed, 

 control in each case being far from complete. The wash containing 

 lime seemed to be the best deterrent, but should have been applied 

 earher. 



No WELL (W.). Infection of Orange Fruit through Bug Punctures.— 

 Agric. News, Barbados, xvii, no. 418, 4th May 1918, p. 142. 



The sweet orange has to be added to the list of fruits serving as 

 hosts for the fungi associated with the internal boll disease of cotton 

 bolls. An orange purchased in Barbados and reputed to have come 

 from Grenada was infested in many spots with a prolific culture of 

 Nemalospora sp. ; there is little doubt that the infection had been 

 introduced by the punctures of some plant-feeding bug.

Wil:mot (N. E.). English Sparrow {Passer domesticus) feeding on the 

 Larva of the Elm-tree Beetle. — U.S. Dept. Agric. Expt. Sta, 

 Record, Washington, DC,, xxxviii, no. 5, April 1918, p. 457. 

 (Abstract from Auk, xxxiv, no. 4, 1917, pp. 479-480.) 



The English sparrow is recorded as feeding on the elm-tree beetle 

 [Galerucella lineola'] in large numbers, and also upon small moths on 

 the wing. May beetles [Lachnosterna], etc. The author is of opinion 

 that the sparrow is becoming more insectivorous every year.
