The eggs of this moth ( Hepticula s 1 i ng e r 1 and e 1 1 a Kearfott) were 
sprayed with Nico-fume (1 oz. in 5 gal» soap solution), but the spraying 
did practically no good. The larvae of the elm sawfly leaf miner 
( Hal i o sy sphing a ulmi Sundeval) while in their mines can be killed with 
a nicotine and soap solution, but less than 10 percent of the larvae 
of the plum leaf miner were killed with "Black Leaf 40" (l to 800 of 
soap solution) .

None of the sprays used was very successful against mature 
larvae of Tischeria m alif oljell a (apple-leaf trumpet miner). Young 
larvae of the second generation were destroyed by sprays of Nico-fume 
or Black Leaf 40 at 1 to 100 or 1 to 200, the mortality ranging from 
73 to 37 percent. Sprays applied for the first generation gave definite 
residual effects on the eggs of the second generation laid 2 or 3 weeks 
later, the mortality on foliage sprayed with nicotine diluted 1 to 100 or 
1 to 200 ranging from 93 to 70 percent as compared with a normal mortality 
of 22 percent .
