The distribution limits of the beet webworm, Loxostege sticticalis L., with its sustainable development in one, two, three, or four successive generations per season in the former USSR territory were mapped for the first time using routine GIS procedures. The expected number of generations was determined based on the sum of daydegrees (above a threshold of 12°C), critical day length value (14 h), and Selyaninov's hydrothermal index (> 0.3). The compiled map was in good agreement with that prepared for China (Luo Li-zhi and Li Guang-bo, 1993). © 2014 Pleiades Publishing, Inc.

Rapid Communications in Mass Spectrometry | Year: 2011

To gain perspective on building full transferable libraries of MSn spectra from their diverse/numerous collections, a new library was built from 1723 MS>1 spectra (mainlyMS2 spectra) of 490 pesticides and related compounds. Spectra acquired on different types of tandem instruments in various experimental conditions were extracted from 168 literature articles and Internet sites. Testing of the library was based on searches where 'unknown' and reference spectra originated from different sources (mainly from different laboratories) were cross-compared. The NIST 05 MS2 library was added to the reference spectra. The library searches were performed with all the test spectra or were divided into different subsamples containing (a) various numbers of replicate spectra of test compounds or (b) spectra acquired from different instrument types. Thus, the dependence of true/false search (identification) result rates on different factors was explored. The percentage of 1st rank correct identifications (true positives) for the only 'unknown' mass spectrum and two and more reference spectra and matching precursor ion m/z values was 89%. For qualified matches, above the cut-off match factor, that rate decreased to 80%. The corresponding rates based on the best match for two and more 'unknown' and reference spectral replicates were 89-94%. For quadrupole instruments, the rates were even higher: 91-95% (one 'unknown' spectrum) and 90-100% (two and more such spectra). This study shows that MS2 spectral libraries generated from the numerous literature/Internet sources are not less efficient for the goal of identification of unknown compounds including pesticides than very common EI-MS1 libraries and are almost as efficient as the most productive from current MS2 spectral databases. Such libraries may be used as individual reference databases or supplements to large experimental spectral collections covering many groups of abundant compounds and different types of tandem mass spectrometers.

A total of 64 species from 17 genera of the family Aphidiidae (Hymenoptera) from Great Britain is identified in the collection of the Manchester Museum (University of Manchester, UK). Nine species are recorded from Great Britain for the first time: Aphidius absinthii Marshall, 1896, A. arvensis Starỳ, 1960, A. linosiphonis Tomanović et Starỳ, 2001, Diaeretellus macrocarpus Mackauer, 1961, Ephedrus longistigmus Gärdenfors, 1986, Monoctonus mali van Achterberg, 1989, Praon uroleucon Tomanović et Kavallieratos, 2003, Trioxys humuli Mackauer, 1960, and T. lambersi Mackauer, 1960. Supplemented descriptions of 2 rare species, Trioxys macroceratus Mackauer, 1960 and T. ibis Mackauer, 1961, are given. © 2016, Pleiades Publishing, Inc.

Data on 15 species of the subgenus Pseudotiorhynchus Magnano, 2004 of the genus Otiorhynchus Germar, 1822 from Kazakhstan, Turkmenistan, and Iran are given. Otiorhynchus lukarevskayae Davidian, sp. n., O. karakalensis Davidian et Savitsky, sp. n., O. konstantini Davidian et Savitsky, sp. n., O. muratovi Savitsky et Davidian, sp. n., O. kopetdagicus Savitsky et Davidian, sp. n., and O. shakhensis Savitsky et Davidian, sp. n. from Turkmenistan, and O. khorasanus Savitsky et Davidian, sp. n. from Iran are described as new to science. A new synonymy is established: Pseudotiorhynchus Magnano, 2004 = Crassorhynchus Magnano, 2004, syn. n.Otiorhynchus iranensis Magnano, 2004 is transferred from the subgenus Protarammichnus Voss, 1960 to the subgenus Pseudotiorhynchus. Lectotype of O. conicirostris Stierlin, 1886 is designated. A key to 15 species of the subgenus Pseudotiorhynchus is given. The new subgenus Microhanibotus Savitsky et Davidian, subgen. n. is established for the new species O. ghilarovi Davidian et Savitsky, sp. n. from the Western Kopet Dagh in Turkmenistan. Microhanibotus subgen. n. is closely related to the subgenera Pseudotiorhynchus, Hanibotus Reitter, 1912 and Nubidanus Reitter, 1912. © 2015, Pleiades Publishing, Inc.

Otiorhynchus schuberti sp. n. (subgenus Dibredus Reitter, 1912) is described from Kahramanmaraş Province in Southeastern Turkey. It is closely related to O. nudiformis Reitter, 1914 and, less closely, to O. rufimanus Hochhuth, 1847, but differs from both in a small bidentate tooth on the fore femur. © 2016, Pleiades Publishing, Inc.

The species composition, structure, and dynamics of arthropod complexes of all the main field crops of Central Chernozem Region of Russia were studied in the course of a long-term biocenological investigation in an agro-ecological station in Kamennaya Steppe. The arthropod complexes of triticale and soybeans, recently introduced in the region, were studied for the first time. The most abundant species which determine the perennial and seasonal dynamics of arthropod abundance on plants were revealed for each crop. A complete characteristic of the arthropod complex on vegetation of the agricultural landscape typical of the Central Chernozem Region is given. © 2016, Pleiades Publishing, Inc.

Improvement of soddy-podzolic soils results in an increase of species richness and abundance of the most common epigeic predatory ground beetle and rove beetle species (Coleoptera: Carabidae, Staphylinidae) in the agrocenoses of Northwestern Russia. © 2015, Pleiades Publishing, Inc.

The systematic positions of the genus Plutodiplosisis, new to the Russian fauna and belonging to the supertribe Lestodiplosidi, stat. n., and the rare genus Triommatomyia [Aphidoletidi (Aphidoletini)] are updated. The two genera are similar in the presence of strongly prolonged sensorial loops of the male flagellomeres. The diagnoses for Aphidoletidi and Lestodiplosidi are supplemented. The genus Plutodiplosis is new to the Russian fauna and includes five species: P. heterofila, P. magnifica, P. festasp. n., P. raphani (Barnes), comb. n. (from Lestodiplosis), and P. venusta (Gagné), comb. n. (from Lestodiplosis). The genus Triommatomyia includes two species, T. barnesi and T. papillata; a supplemented description of the latter is included. Keys to the species of the genera Plutodiplosis and Triommatomyia are given. © 2015, Pleiades Publishing, Inc.

In 1979-2008, serological investigation of carabid beetles as predators of the Colorado potato beetle was carried out in the fields of potato and other Solanaceae crops in nine regions of Russia, Moldova, and Ukraine. The fraction of carabid beetles feeding on the pest in the potato, tomato, and egg-plant fields grows with the duration of the pest presence in the region and is proportional to its population density. © 2012 Pleiades Publishing, Ltd.
