Nicotine sulphate 1:500 or 1:800 kills about 70 percent of the 
eggs of (Laspeyresia) G-rapholitha molesta (oriental peach moth).

Nicotine (1 to 500 soap solution), nicotine resinate (1 to 500), 
and tobacco dust were tried against these larvae, ( Laspeyresia ) G-rapho- 
litha molesta Busckfr, but they were found ineffective (pp. 395-395) .

In detailed laboratory tests and as applied to single trees in 
the orchard, Black Leaf 40 as an ovicide, and nicotine-arsenical com- 
binations in applications near hatching time, have proved most effective, 
a three-fourths control having been secured.

A SECOND REPORT. Jour. Econ. Snt. 14: 336-341. [Abstract in Rev. Appl.

Nicotine at 1 to 1,600 produced practically no check on the hatch- 
ing of the eggs, but its effectiveness' was slightly increased by a case- 
inate spreader at the rate of 1 lb. to 50 gal. or sea moss at the rate of 
2 lb. to 50 gal. A dilution of 1 to 800 reduced the hatching by about 
two-thirds and a dilution of 1 to 500 reduced it oy about three-fourths. 
An arsenical and nicotine spray did not satisfactorily kill the young 
larvae .

Spraying with nicotine sulphate in America has destroyed as high as 
75 percent of the eggs of this moth on peach trees. Using the same materi- 
al, Black Leaf 40 (1:800), applications should be made in France on May 17, 
June 2, July 27, and August 28, corresponding approximately to the time of 
oviposition (p. 22).
