Dustings were made with 3 percent nicotine-lime dust to determine 
the hud moth and parasite population in the lighted and unlighted areas 
of the orchard. These dustings indicated from 2 to 7 times as many hud 
moths in the unlighted area as in the lighted area. Parasites and fruit 
tree leaf rollers were also more numerous in the unlighted section 
(p. 32).

Under very favorable weather conditions, such as still warm 
days, reasonable results may be expected from a thorough application 
of a dust containing not less than 6 percent nicotine sulphate. I7here 
power spraying equipment is available, a spray of 1 l/2 to 2 gal. highly 
refined oil emulsion and 1 l/2 pt. nicotine sulphate in 200 gal. water 
is recommended.

Spraying with nicotine sulphate distillate emulsion mixture did 
not prove successful. Various strengths of Nicodust also gave nega- 
tive results against this species ( Euthrips tritic i or possibly E. 
he li ant hi ) .
