Аннотация:
Features of external environmental factors (such as electromagnetic radiation in certain spectral bands) influencing
pheromone molecules, which are carriers of information for forest insects in the search of the opposite sex, were
examined. Stability of pheromone molecules for external influences has been studied for siberian moth Dendrolimus
superans sibiricusTschetv., pine moth Dendrilimus piniL., gypsy moth Lymantria disparL., for xylophages Ips
typographus L., Monochamus urussovi Fish. and Monochamus galloprovincialis Oliv. Properties of pheromone
molecules were evaluated by calculations using quantum-chemical method B3LYP. Existing methods of quantum-chemical calculations are useful for analyzing the properties of quite small and uncomplicated molecules of forest
insect pheromones. The calculations showed that the molecules of insect pheromones are able to absorb light in the
ultraviolet range and move into an excited state. The values of dipole moments, the wavelengths of the absorption,
atomic and molecular electronic properties of pheromones in the ground and excited states were calculated. The
calculations showed that for the reaction of pheromones with oxygen an energy barrier is somewhat higher than
for reactions of pheromones with water vapor. The worst reaction of pheromones with water molecules likely to
pheromones such molecules whose dipole moment is comparable to the dipole moment of water. Quantum-chemical
characteristics of the pheromone molecules can be linked to specific behavior of the insects.
