(5) Moths identify those of the opposite sex 
and are stimulated to mate (clasper response) 
by chemical releasers (scent), In this regard, 
in view of the many different types of antennal 
and other spines, it may well be that the IR or 
microwave emission of scent molecules them- 
selves is tuned in by the resonance of certain 
Spine transducers that transfer the signal 
from the molecule to the nervous system 
(Callahan 1965b), 
SUMMARY 
A completely new concept of the insect en- 
vironment is introduced. It is based on inter- 
mediate and far infrared frequency transmis- 
sions through infrared atmospheric windows. 
This concept involves the utilization of such 
transmitted frequencies in the life cycle and 
behavior of the insect. Considerable evidence 
indicates that host location and insect com- 
munication depend on the detection of such 
frequencies in the 1- to 18-4 spectrum. Fre- 
quency transmissions in the 9-yu region have 
been received, amplified, and recorded on an 
oscilloscope from moths in the families Noc- 
tuidae, Sphingidae, and Lasiocampidae. In 
addition, various species of Noctuidae have 
been attracted to a blackbody emitting in the 
9- uw region in a totally dark room.
