Аннотация: Представлены расходы энергии корма (хвои лиственницы) непарного шелкопряда на разных этапах онтогенеза. Показано распределение общей энергии корма (%) на метаболизм, создание экзувиев непарного шелкопряда на протяжении всего развития, создание имаго. Доля потребленной энергии корма, расходуемая на экскременты за весь период питания, одинакова у самок и самцов непарного шелкопряда и составляет 58%. Ассимилированная часть потребленной энергии корма распределяется у самок и самцов различно. На создание бабочек-самок, их экзувиев расходуется большее количество, чем у бабочек-самцов. Доля потребленной энергии корма затраченная на метаболизм непарного шелкопряда в процессе всей его жизни одинакова как у самок, так и самцов и составляет ~ 30%.

Аннотация: В ходе онтогенеза оптимальная плотность содержания гусениц сибирского шелкопряда Dendrolimus superans sibiricus Tschtvr. изменялась: в I-IV возрастах преимущество получали особи, живущие в группах, тогда как в VI возрасте - живущие поодиночке. Перелом, уравнивающий основные показатели питания и роста у одиночных гусениц и выращенных в группах, наблюдался в V возрасте. В I-III возрастах совместное обитание особей благоприятно воздействовало на выживаемость, в III-IV - на интенсивность развития за счет повышения экологической эффективности использования потребленного и усвоенного корма на рост. Относительная скорость потребления корма и показатель усвоения корма не зависели от плотности содержания гусениц. Влияние плотности на показатели питания и уровень выживания проявлялось уже при содержании трех гусениц в одном садке и не менялось при увеличении их числа до 20.

Аннотация: Выявлен основной состав полового аттрактанта для самцов соснового шелкопряда Dendrolimus pini L. (Lepidoptera, lasiocampidae) в азиатской части ареала вида. Это смесь Z5, E7-додекадиеналя и Z5, Е7 - додекадиенола в соответствии 1000:500, соответственно. Смесь оказалась аттрактивной для самцов алтайской и приенисейской популяции шелкопряда. Z5, E7-додекадиенилацетат и Z5, Е7 - додекадиенилпропионат являются, по-видимому, ингибиторами полового поведения самцов шелкопряда. Добавление их к основной смеси уже в малых дозах резко снижает привлекательность ловушек.

Аннотация: A model of the population dynamics of insects has been developed, which takes into account the food consumption by insects and the reaction of food plants to the damage. Equations have been derived that describe the relationship between the coefficient of insect reproduction, the weight of females, the energetic effectiveness of the food consumption by insects, and the reaction of food plants. The scenarios of population outbreaks have been analyzed as a function of the weight of females in the stable state. The results of modeling have been compared with the data of natural observations.

Аннотация: Food energy expenditures by gypsy moth at different developmental stages under conditions of feeding on larch needles are described. The distribution of total food energy (%) for metabolism, the formation of exuvia (throughout ontogeny), and the formation of an adult insect is assessed. The proportion of food energy lost with excrements over the entire period of feeding is the same (58%) in females and males. The assimilated part of food energy is distributed differently: energy expenditures for the formation of exuvia and adult insects are greater in females than in males. The proportion of food energy expended for metabolism throughout the insect life span is approximately 30% in both females and males.

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: 1 The native range of the Siberian moth extends from the Pacific Ocean (Russian Far East, Japan and Northern Korea) across Siberia, Northern China and Mongolia to the Ural Mountains. At the beginning of the 21st Century, this species was documented west of the Ural Mountains in the Republic of Mari El, indicating range extension toward the west. 2 The Siberian moth has recently been suggested for regulation as a quarantine pest for European and Mediterranean Plant Protection Organization member countries. However, no specific report on European host plants for this pest has been published so far. 3 In the present study, larval host plant choice and performance was tested for the first time on coniferous tree species that are widely distributed and of commercial value in Europe. 4 Based on dual-choice tests on neonates and mortality, developmental duration and relative growth rates of the first- to sixth-instar larvae, we found European larch Larix decidua to be the most suitable host for the moth larvae, whereas European black pine Pinus nigra and Scots pine Pinus sylvestris were the poorest hosts. The remaining conifer species tested, European silver fir Abies alba, Nordmann fir Abies nordmanniana, and Norway spruce Picea abies, were intermediate host plants. Douglas-fir Pseudotsuga menziesii, originating from North America, was chosen by the larvae to the same extend as European larch, and was also highly suitable for larval development. 5 If the moth is introduced to European countries, it will become damaging in stands of European larch and Douglas-fir, mixed stands of fir and spruce; however, it will be less damaging in forests dominated by two-needle pines. 6 We predict that Dendrolimus superans sibiricus will be able to survive and develop on the main European coniferous tree species, including non-native coniferous tree species, resulting in severe damage to large areas of forests.

Аннотация: The optimal density of larvae in Siberian moth (Dendrolimus superans sibiricus) kept in chambers varied in ontogenesis: the larvae living in grups predominated in the I-st-IVth instars, whereas those living alone, in the VIth instar. The critical moment equalizing feeding and growth parameters in single larvae and those grown in groups was observed in the V-th instar. The larval aggregation favored the survival rate in the I-st-IIIrd instars and the developmental intensity in the IIIth-IVth instars due to the higher efficiency of using food (ingested and digested) for growth. The relative growth rate and digestibility of food did not depend on the density of larval populations. The effects of density on feeding and growth parameters, as well as on the survival rate, were displayed even when three larvae were kept in one chamber. The increase of the number of larvae up to 20 did not change these effects.

Аннотация: The importance of summer diapause in Siberian moth larvae in the intrapopulation synchronization of hatching imago is estimated. The larval stage becomes longer due to reducing food consumption and efficiency of its utilization by larvae, despite favorable conditions of their development. The summer diapause in larvae of the IVth instar increases the developmental period up to 3 weeks and lowers significantly a relative rate of food consumption as compared to the control specimens. The diapausing larvae digested food by 20% less than the control ones. The efficiency of using the food for the growth of insects was 2 times lower. As a result, the relative growth rate in the diapausing larvae has reduced by 8 times (0.009 vs. 0.073 mg/mg per day).

Аннотация: Оценена роль летней диапаузы гусениц сибирского шелкопряда. DENDROLIMUS SUPERANS SIBIRICUS Tschtvr., во внутрипопуляционной синхронизации появления имаго. Удлинение личиночной стадии происходит за счет снижения потребления, усвоения и использования корма, несмотря на благоприятные условия развития. На примере гусениц IV возраста показано, что летняя диапауза увеличивает до 3 недель период прохождения возраста и существенно снижает относительную скорость потребления корма по сравнению с контрольными особями. У диапаузирующих гусениц на 20% снижается коэффициент усвоения корма и в 2 раза понижается эффективность использования на рост потребленного и усвоенного корма. В результате относительная скорость роста у диапаузирующих гусениц снизилась в 8 раз (0,009 мг/мг/сут против 0,073 мг/мг/сут в контроле).

Аннотация: The Siberian moth, Dendrolimus sibiricus, Tschtv. is the most harmful defoliator of coniferous forests in North Asia. The pest has already spread over the Urals and continues moving westwards. Recently, it has been recommended for quarantine in member countries by European and Mediterranean Plant Protection Organization (EPPO). The performances of the pest on coniferous species planted in Europe were assessed on a range of potted trees corresponding to the spectrum of economically important conifers in the EU: European larch Larix decidua, Norway spruce Picea abies, Scots pine Pinus sylvestris, European black pine Pinus nigra, and the North American species: Douglas fir Pseudotsuga menziesii and grand fir Abies grandis. Larvae showed a potential to survive and complete the development on all these host tree species. Favorable hosts were grand fir, European larch, and Douglas fir that allowed higher survival, better larval development, and as a result, yielded heavier pupae and adult moths with higher longevity. Black pine was a poor host but, however, could still support larval and pupal development. Norway spruce and Scots pine had an intermediate behavior. If accidentally introduced to Europe, the Siberian moth may become especially damaging in forest stands predominated by European larch and by the North American firs. Norway spruce and especially the two-needle pines will be less prone to intensive defoliation by this species. The fact that the pest may damage the range of economically important coniferous species should be taken into account in the pest risk assessment for Europe and also for North America where the Siberian moth occurrence is considered likely.

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 performance of young larvae of the potentially invasive Siberian moth Dendrolimus sibiricus Tschtv. has been studied for the first time on the native and exotic coniferous species which are widely distributed and of considerable commercial value in Europe. Picea, Abies, the introduced Pinus species (five-needle pine only), and species from the exotic genera Pseudotsuga and Cedrus (all Pinaceae) are found to be suitable hosts for pest development. Two-needle pines and species from non-native Tsuga (also Pinaceae) are poor hosts in terms of larval performance though they may support growth of neonates (most sensitive to food quality). Coniferous species from other families: Taxaceae and Cupressaceae are inedible for the pest. The fact that the Siberian moth is able to survive and develop on all the tested genera of Pinaceae and that some of them constitute two thirds of the European forests underline how harmful this defoliator could be in the case of its introduction into European countries.

Аннотация: Mechanical treatment and prescribed fire were used to restore a mixed conifer stand (Picea-Abies-Pinus) following mortality from an outbreak of Siberian moth (Dendrolimus superans sibiricus). Moth-killed stands often become dominated by Calamagrostis, a sod-forming grass. The large amount of woody debris and the sod hinder coniferous seedling establishment and development as well as creating conditions favorable to the establishment and propagation of wildfires. Fire has been demonstrated to be an effective method of reducing woody debris and eliminating sod, but the random nature and timing of wildfires often do not create conditions favorable for conifer regeneration. Our study was conducted in a mature fir dominated stand that died during an outbreak 6-8 years previously with most of the dead trees still standing. A bulldozer drove through the stand downing standing snags in late summer with 15-20 m between passes. Snags knocked down by the bulldozer and additional snag fall throughout the following winter increased downed dead wood 50-60% and large downed dead wood 80% compared to an adjacent untreated area. In June, a prescribed fire was set and fuel load consumption averaged 70%. Average soil temperatures during the burn ranged from 47В°C at a depth of 2 cm to 10В°C at 10 cm; hot enough to kill the grass. Following treatment, the potential for wildfire was reduced and the area was suitable for either natural conifer regeneration or planting without further mechanical site preparation.

Аннотация: Field trapping experiments were conducted against the Siberian moth, Dendrolimus superans sibiricus Butler, in Siberia, Russia, using traps baited with a virgin female moth or 100 ?g synthetic mixtures of C 12 straight chain-length aldehydes, alcohols, and acetates alone or in combinations on rubber septa. Traps baited with a 1:1 blend of aldehydes and alcohols captured many males. The capture rate was similar to the rate of capture seen in traps baited with virgin females. The mixture of aldehydes and alcohols (64% Z,E-5,7-dodecadienal, 10% Z-5-dodecenal, 18% E-7-dodecenal, 8% E-6-dodecenal) and (64% Z,E-5,7-dodecadien-1-ol, 10% Z-5-dodecen-1-ol, 18% E-7-dodecen-1-ol, 8% E-6-dodecen-1-ol) can be used as a sex attractant to monitor endemic Siberian moth populations in Asia, and for surveillance and detection of the moth in countries where the insect might be accidentally introduced.

Аннотация: An experimental procedure was developed to visualize the vortex wake of free-flying insects. Neotropical Heliconius erato butterflies were filmed hovering inside a transparent plexiglas cube. A dispersed cloud of Sephadex particles was used as the visualization medium. The flow field around the flying insect was illuminated with a planar laser beam, thereby generating a cross-sectional perspective of the three-dimensional vortex wake. Thirty-seven flight sequences from five individuals were filmed for analysis. A variety of vortex structures was observed, although the most likely form of the wake in slow forward flight is a series of distinct vortex rings.
