Аннотация: Efficient syntheses of (ZE)-5,7-dodecadienol, a pheromone component of the Siberian moth, Dendrolimus superans sibiricus, and (E,Z)-10,12-hexadecadienol, a pheromone component of various Lepidoptera pheromones, were accomplished by cis reduction of the corresponding enynols with activated zinc. The most energetic reagent was zinc galvanized with copper and silver (Zn/Cu/Ag) that achieved rapid and high-yield reduction in methanol-water. The stereoselectivity of semihydrogenation was greater than or equal to98%. A process whereby zinc dust was continuously activated throughout the reduction with an acid was also satisfactory (95-98% cis). Field evaluation of the 1:1 mixture of (Z,E)-5,7-dodecadienol and (Z,E)-5,7-dodecadienal with the Siberian moth in Russia showed that the rubber septa pretreated with compound and stored at -80 degreesC were as effective as freshly treated septa. Moth responses to septa aged in open air indicated that lure effectiveness declined significantly after 2 weeks of aging. Thus, if rubber septa are used as pheromone dispensers in Siberian moth traps monitoring, they should be replaced biweekly with fresh septa for optimal trap effectiveness.

Аннотация: In field studies in the Russian Far East, five types of illuminating devices were evaluated for attracting adult gypsy moth, Lymantria dispar (L.), pink gypsy moth, L. mathura Moore, and nun moth, L. monacha (L.). Our objective was to determine if light from commercial lamps suited to out-of-doors floodlighting could be modified to reduce their attractiveness to moths without a reduction of illumination. During 17 nights of tests, fluorescent blacklight lamps captured significantly more adults than either phosphor mercury or high-pressure sodium lamps, Captures were slightly higher for phosphor mercury than high-pressure sodium lamps but both were unattractive to all three lymantriids after the addition of filters that blocked spectral emissions <480 nm. Daily temporal periodicity, based on adult captures at lights, resulted in distinct activity patterns for the three lymantriids. Peak activity for L. dispar was between 2300 and 0100 hours; for L. mathura, 0100-0300 hours; and 0300-0500 hours for L. monacha. Temporal activity patterns suggest that L. dispar and L. monacha possess nonoverlapping diel rhythms, whereas L. mathura overlaps broadly with both L. dispar and L. monacha.

Аннотация: Male Asian gypsy moths, Lymantria dispar (L.), were attracted to synthetic pheromone (cis-7R,8S-epoxy-2-methyloctadecane) in the Russian Far East, Central Siberia, and Germany, where this strain has recently been detected. A bimodal pattern of attraction was evident at all 3 sites. One peak of attraction was in early to midafternoon, with a 2nd, usually smaller peak, following sunset. Temperature modulated attraction: warm daytime temperatures increased catch, whereas low nighttime temperatures generally suppressed or eliminated attraction. However, the surge of male attraction to pheromone in the hour after sunset seemed unaffected by falling temperatures. As average temperatures at the 3 sites decreased, the daytime peak of male activity progressively shifted to later in the afternoon. Female eclosion in Germany also followed a bimodal pattern, with a major midmorning to midday peak of emergence and a 2nd, smaller peak, in the afternoon. The timing of male attraction allowed coordination of the ranging flight of the male with the availability of emerging and pheromone-emitting females. The congruence in daily activity patterns suggest that the timing of mating would not be a barrier to the hybridization of the Asian, European, and North American strains of this lymantriid in new areas of sympatry.

Аннотация: A quantum-chemical study has been made of the interactions of pheromones of some lepidopteran forest pests (Siberian moth Dendrolimus superans sibiricus Tschetv and gypsy moth Limantria dispar L.) with components of the ambient air, as well as the effect of electromagnetic radiation on the pheromones. It is found that the reactions of pheromones with substances contained in the forest air are irreversible and proceed with liberation of heat. Electromagnetic radiation quite strongly affects the structure of pheromones, whereby the pheromone molecule is activated and can readily enter into reactions. В© 2011 Pleiades Publishing, Ltd.

Аннотация: The B3LYD /6-31(p,d) density functional method is applied to pheromones of the forest xylophagous insects Ips typographus L., Monochamus urussovi Fisch., and Monochamus galloprovincialis Oliv. to calculate the absorption spectra and find excited states. The calculated results are used to assess the possible activity of the molecules when they are affected by solar radiation.

Аннотация: The ground and excited states of the pheromone molecules produced by xylophagous insects (the bark beetle Ips typographus L., the black fir sawyer beetle Monochamus urussovi Fisch., and the black pine sawyer M. galloprovincialis Oliv.) were modeled using a quantum chemical method utilizing DFT (density functional theory) with the B3LYP functional. The absorption wavelengths (energies) and dipole moments were calculated; the transitions of electrons from occupied to empty molecular orbitals were considered. The computed data were used to assess the stability of pheromone molecules exposed to environmental factors, such as solar radiation and humidity. © 2017, Pleiades Publishing, Inc.

Аннотация: The correlation between the kinetic stability of molecules against temperature and variations in their geometric structure under optical excitation is investigated by the example of different organic pheromone molecules sensitive to temperature or ultraviolet radiation using the density functional theory. The kinetic stability is determined by the previously developed method based on the calculation of the probability of extension of any structural bond by a value exceeding the limit value Lмах corresponding to the breaking of the bond under temperature excitation. The kinetic stability calculation only requires the eigenfrequencies and vibrational mode vectors in the molecule ground state to be calculated, without determining the transition states. The weakest bonds in molecules determined by the kinetic stability method are compared with the bond length variations in molecules in the excited state upon absorption of light by a molecule. Good agreement between the results obtained is demonstrated and the difference between them is discussed. The universality of formulations within both approaches used to estimate the stability of different pheromone molecules containing strained cycles and conjugated, double, and single bonds allows these approaches to be applied for studying other molecules.
