it may be even possible to utilize electric 
lights as attractants for partial or complete 
control of certain insects, Extensive instal- 
lations of light traps have been made by 
tobacco farmers in Kentucky, North Carolina, 
and South Carolina during the 1964season, and 
a rather large acreage of cotton will be covered 
during the 1965 season in Texas, 
The efforts described are in line with other 
projects intended to improve both ground and 
air equipment for applying chemicals more 
precisely so that pests may be controlled more 
efficiently without adversely affecting growing 
plants or animals, Primary emphasis is being 
given in many projects to elimination of pesti- 
cide residues, including the reduction of drift, 
Rapid methods of measuring pesticide deposits 
are continuing to be developed and investigated, 
The development of granular pesticides for 
insect and weed control has been especially 
helpful, and their use for pest control is ex- 
panding so rapidly that it is now unusual to 
find a pesticide that is notavailablein granular 
form, 
These are only a few examples of produc- 
tive work, and the opportunities for useful 
physical and engineering research, as progress 
is made, will increase rather than decrease,
