Revision of Mecinus heydenii species complex (Curculionidae): integrative taxonomy reveals multiple species exhibiting host specialization
(Wiley-Blackwell, Hoboken, 2014)
A combined taxonomic, morphological, molecular and biological study revealed that the species presently named Mecinus heydenii is actually composed of five different species: M.heydenii Wencker, 1866; M.raphaelis Baviera ...
Biology and host specificity of Rhinusa pilosa, a recommended biological control agent of Linaria vulgaris
(Springer, Dordrecht, 2014)
Linaria vulgaris Mill. (Plantaginaceae), common or yellow toadflax, is a Eurasian short-lived perennial forb invasive throughout temperate North America. Rhinusa pilosa (Gyllenhal) (Coleoptera, Curculionidae) is a univoltine ...
Identification and genetic characterisation of xanthomonas campestris pv. Campestris as an oilseed rape pathogen in serbia
(Edizioni Ets, Pisa, 2014)
During 2010, black rot symptoms were observed in oilseed rape plants grown in a commercial plot in Serbia. Ten bacterial isolates obtained from diseased plants, and identified as Xanthomonas campestris pv. campestris (Xcc) ...
Effect of Cobalt Application on Seed Production in Red Clover (Trifolium pratense L.)
(Tarbiat Modares Univ, Tehran, 2014)
A field experiment involving red clover varieties K-39, K-17, Una and Viola was established on an acidic (pH(H2O) 4.8) soil to evaluate the effects of foliar application of cobalt (a beneficial nutrient for efficient ...
Molecular and morphological variability within the Aphidius colemani group with redescription of Aphidius platensis Brethes (Hymenoptera: Braconidae: Aphidiinae)
(Cambridge Univ Press, Cambridge, 2014)
We have identified the following three taxa related to the Aphidius colemani species group, which are important biological control agents: Aphidius colemani, Aphidius transcaspicus and Aphidius platensis. Using partial ...
Characterization and phylogenetic diversity of Agrobacterium vitis from Serbia based on sequence analysis of 16S-23S rRNA internal transcribed spacer (ITS) region
(Springer, Dordrecht, 2014)
Serious outbreaks of grapevine crown gall disease were observed in major Serbian viticultural regions during the last five years. Tumorigenic Agrobacterium vitis was identified as a causal agent by using conventional ...
Geometric morphometric study of geographic and host-related variability in Aceria spp. (Acari: Eriophyoidea) inhabiting Cirsium spp. (Asteraceae)
(Springer, Dordrecht, 2014)
The russet mite, Aceria anthocoptes (Nalepa), is the only eriophyoid that has been recorded on Cirsium arvense (L.) Scop. It has been noted in several European countries and recently in the USA. In this study we explored ...
Biological control of Rhamnus cathartica: is it feasible? A review of work done in 2002-2012
(Wiley-Blackwell, Hoboken, 2014)
Rhamnus cathartica (common buckthorn) is a shrub (or small tree) of Eurasian origin, which has become invasive in North America. Internal feeders and sap suckers were prioritized for biological control from over 30 specialized ...
The Praon dorsale-yomenae s.str. complex (Hymenoptera, Braconidae, Aphidiinae): Species discrimination using geometric morphometrics and molecular markers with description of a new species
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2014)
In this paper we apply an integrative approach combining morphometric and molecular analyses to explore parasitoids of the Praon dorsale-yomenae s.str. complex. These parasitoids occur in natural and agricultural ecosystems ...
