To the knowledge of some species of the genus Paederidus Mulsant & Rey, 1878 (Coleoptera: Staphylinidae: Paederinae) from the Western Palaearctic   Khachikov Eduard A. Southern Federal University, Rostov-on-Don, Russia. e_hachikov@mail.ru Abstract We studied the morphology of endofallus of species Paederidus ruficollis (Fabricius, 1777), P. sanguinicollis (Motchulsky, 1860), P. punctiventris Scheerpeltz, 1957, P. rubrothoracicus (Goeze, 1777) and related forms from the Caucasus, Europe, Turkey and Algeria in this paper. This allowed is making additions to the European fauna of the genus Paederidus Mulsant & Rey, 1878: selected the new subspecies P. ruficollis carpaticus subsp. n. from the Western Ukraine. And just to clarify the species composition of the same genus in the Northern Caucasus, is including three species: Paederidus caucasicus Scheerpeltz, 1957, nom. resurr. = P. sanguinicollis (Motschulsky, 1860), syn. n.; P. punctiventris and Paederidus sp. 1, and excluded from the fauna of this region species – Paederidus ruficollis and P. rubrothoracicus.  

Effect of Combined Magnetic Fields with Very Weak Alternating Component on Duration of Pupal Metamorphosis Stage in Mealworm Beetle Tenebrio molitor It is shown that an exposure of pupae of the mealworm beetle Tenebrio molitor to the combined static (42 µT) and very weak extremely low-frequency alternating collinear magnetic fields exerts different influence, depending on the frequency of the alternating magnetic field (AMF), on duration of metamorphosis processes in these insects. For instance, a no less than 8 hour-exposure of young pupae to weak combined magnetic fields, adjusted to the frequency of ion cyclotron resonance for Ca2+ (32.2 Hz) at the AMF of 100 and 250 nT, inhibits metamorphosis process – a transitional stage from pupae to imago lasts longer. In contrast, a stimulating effect was observed when adjusted to cyclotron frequency for ion of glutaminic acid (4.4 Hz) at the amplitudes of 40, 100 and 250 nT. At the weaker amplitudes of the AMF this effect is not seen. For instance, an exposure at a frequency of 4.4 Hz, the amplitude of AMF 6, 16 nT and at a frequency of 32.2 Hz, the amplitude of AMF 6, 16 and 40 nT exerts no noticeable effect on the duration of the pupal metamorphosis stage.

The relationship the biochemical composition of artificial nutrient media, morphological and physiological indicators of larvae great wax moth (Galleria mellonella L.) The article presents the research to explore the relationship of biochemical composition of the studied artificial nutrient media and morphological, physiological indicators of larvae of Galleria mellonella. To explore this issue was taken up widely used artificial nutrient media. This artificial nutrient media includes such ingredients as flour, dry milk, brewer's yeast, honey, glycerin, bran, beeswax, water. Material studies are the greater wax moth larvae (Galleria mellonella L.) and artificial nutrient media, which prepared according to the recipes of different authors. Statistical analysis showed that the significant relationship of the studied biochemical and morphological indicators. Calculation of correlation of the analyzed indicators have revealed a strong positive correlation between the content of initial moisture in the larvae and their survival (+0,80). The maximum initial moisture in the larvae observed in the experimental group according to the recipe of V. Ya. Ismailov and others № 1 of 68,05 %, while the survival rate in this group was 84,17 % by 11,44% above the control. Also the average negative correlation was revealed between ash content and mass of larvae (-0,66). In addition, the average direct correlation was revealed of the content of crude protein in the feed and crude protein in larvae (+0,64). Noted that the initial moisture of larvae and crude fat in the artificial nutrient media has a reverse correlation – -0,71. Thus, the artificial nutrient medium, balanced in protein, fat and carbohydrates, significantly increases the biological capacity of the insect. Recipe of Russian scientists E. M. Shagov, I. G. Ulanova, E. M. Aslanyan  [7] is selected from considered artificial nutrient media on a number of morphological and physiological indicators.
