Responses of an idiobiont ectoparasitoid, Spathius galinae, to host larvae parasitized by the koinobiont endoparasitoid Tetrastichus planipennisi: implications for biological control of emerald ash borer
Understanding interspecific competition among insect parasitoids is important in designing classical biological control programs that involve multiple species introductions. Spathius galinae, a new idiobiont ectoparasitoid from the Russian Far East, is currently being considered for introduction to ...
Spathius galinae Belokobylskij & Strazajac is a recently described parasitoid of the emerald ash borer, Agrilus plannipennis Fairmaire, in the Russian Far East, and is currently being considered for biocontrol introduction in the US. Using A. planipennis larvae reared with freshly cut ash (Fraxinus ...
Effect of Parasitoid: Host Ratio and Parasitoid and Host Group Size on Fitness of Spathius galinae (Hymenoptera: Braconidae), a Parasitoid of Emerald Ash Borer (Coleoptera: Buprestidae): Implications for Mass-Rearing
Producing insect natural enemies in laboratories or insectaries for biological pest control is often expensive, and developing cost-effective rearing techniques is a goal of many biological control programs. Spathius galinae Belokobylskij and Strazenac (Hymenoptera: Braconidae), a recently described...
Host-specificity determination prior to the introduction of non-native natural enemies (predators and parasitoids) is a critical component of the risk assessment for modern classical biological control programs. In the present study, we assessed the host specificity of a newly described parasitoid,...

A method used to study the evolution of radiating dissipative fluid spheres is applied to the case in which the space-time admits a homothetic motion. We obtain a system of equations at the surface of the distribution which is integrated numerically. Considering that the shear viscosity induces anisotropy, we obtain a model derived from the static solution by Herrera, Jiménez, Leal, Esculpi, Ponce de León, and Galina [J. Math. Phys. 25, 3274 (1984)] for homothetic fluids but which includes dynamic variables. Therefore, the profiles of the physical variables at the surface are calculated and discussed in the light of one astrophysical scenario.

The JENAM symposium "Physics of Stars" took place on the 5th and 6th July of 2011 in Saint-Petersburg. This symposium had a wide-ranging look at observational and theoretical studies of stars and stellar systems. Several talks were devoted to accurate determination of fundamental stellar parameters, such as star's mass, radius, effective temperature, surface gravity, chemical composition. This is particularly crucial to fully exploit the data from the new generation of large ground-based telescopes and future space missions like the GAIA one. Viktor Orlov reported the measurements of stellar mass for a few multiple systems and also the investigation of their dynamical stability. To improve the determination of parameters of the components in an eclipsing binary system including a Wolf-Rayet star, Eleonora Antokhina and her co-workers updated their synthesis model by accounting for the absorption in the expanding stellar wind. The variable stars are excellent laboratories to study the physical processes either occurring at certain stages of stellar evolution or caused by the interaction of a star with its companion or circumstellar medium. Nikolay Samus reported the discovery of hundreds of new variable stars in their work on digitalization of the Moscow stacks of sky photographs. The exotic star VSX J052807.9+725606, with a very strong asymmetry of maxima, wavelength dependence of amplitude, and the shift of the secondary minimum from the phase 0.5, was discovered by Natalia Virnina. Michael E. Contadakis and his co-workers presented the additional observational evidences for weak transient optical oscillations of the red dwarf AD Leo. Spectral variability of the two massive luminous stars in the M33 galaxy was studied by Olga Maryeva. Alex Dudorov and Sergei Zamozdra and Alexander Grigoriev et al. discussed the theoretical and observational problems of star formation. Galina Dremova presented the numerical algorithm for computing the tidal torque constants for a

PHOTO CAPTION ESO PR PHOTO 10/94-1: PORTRAIT OF A DOOMED COMET These two photos from the ESO La Silla observatory show the individual nuclei of comet Shoemaker-Levy 9, now headed for collision with Jupiter on 16 - 22 July 1994. The wide-field photo (below, left) was obtained by Klaus Jockers and Galina Chernova (Max-Planck-Institute fur Aeronomie, Katlenburg, Lindau, Germany) on May 1, 1994. For this 5 min exposure in red light they used a CCD camera at the MPIfAe/Hoher List focal reducer at the ESO 1-metre telescope. The entire nuclear train (the "string of pearls") is very well seen, together with the sunlight-reflecting dust from the nuclei, all on one side. On this date, the comet was 654 million km from the Earth and the angular extension of the train was about 5.3 arcmin, corresponding to a projected length of just over 1 million km. A 15 min CCD image was obtained for astrometric purposes on May 11, 1994, by Jean-Francois Claeskens at the Danish 1.5 m telescope at La Silla; it is here reproduced in close-up to show well the individual nuclei, in particular the fainter ones. The bright object to the upper right is a 10th mag star. Note that the stars in the field are somewhat trailed, since the telescope was set to follow the motion of the comet. The first nucleus to hit Jupiter will be "A", here seen 42 mm from the left edge and 33 mm below the upper edge of the large picture. The last is "W", 43 mm above the lower edge and 9 mm from the right edge. The comet was 657 million km from the Earth and the train was somewhat longer, 5.8 arcmin, i.e. the projected length was now 1.1 million km.
