Against aphid eggs, Black Leaf 40 (1:1000) was used in combina- 
tion with lime-sulphur, home-made distill. ate oil emulsion, commercial 
miscible oil, commercial distillate oil emulsion, "Yel-Ros", commercia 
crude oil emulsion, liquid whale-oil soap, and asphalt emulsion. In 
nearly every test no aphids ( Aphis pomi and A. sorbi ) appeared on the 
sprayed leaves.

Leafhopper nymphs on apples, especially in the earlier stages 
are very susceptible to nicotine. Timely and thorough spraying with 
miscible oil and nicotine sulphate is the most promising remedial 
measure against pear thrips ( Taeniothrips inconsequens Uzel.). Applic 
tions of lime-sulphur and nicotine sulphate afford a certain amount of 
protection against the rosy aphid (Aphis sorbi Kalt.).

One or two applications of an oil (Be. 16-17, viscosity 1,200 a 
70° P.) at 1 to 20 plus nicotine sulphate (40-percent) at 1 to 400 ma<3

tion Toy this cecidomyiid. A second application should follow in about 
a week.

The oest control for M. "ouxi is spraying with molasses, 1 part 
to 4 parts water plus nicotine sulphate (40-percent) 1 to 500. The oil 
and nicotine sulphate spray recommended by Primm and Hartley [Rev. App 
Ent. (A) 11: 533] was tested and gave fairly good control but caused 
considerable scorching. Molasses and tobacco dust was not so effective 
Pree nicotine was found in laboratory tests to be less satisfactory t 
nicotine sulphate.
