Myrrha octodecimguttata (Linnaeus, 1758) and Epuraea ocularis Fairmaire, 1849 are recorded from Israel for the first time, both species collected in Shoham Forest.
Background: The African wolf, for which we herein recognise Canis lupaster Hemprich and Ehrenberg, 1832 (Symbolae Physicae quae ex Itinere Africam Borealem er Asoam Occidentalem Decas Secunda. Berlin, 1833) as the valid species name (we consider the older name Canis anthus Cuvier, 1820 [Le Chacal de Sénégal, Femelle. In: Geoffroy St.-Hilaire E, Cuvier F, editors. Histoire Naturelle des Mammifèr...
In this study, sea bass (Dicentrarchus labrax, Linnaeus, 1758), gray mullet (Chelon labrosus, Aisso, 1826), bream (Spanus aurata, L. 1785) and carp (Cyprinus carpio, L. 1758) supplied from Bafa Lake from October 2013 to February 2014, underwent a parasitological examination for helminth parasites. In total 86 fish were examined and four helminth species (Diplactanum aequans, H...
Previous studies detected an influence of urban characteristics on song traits in passerine birds, that is, song adjustments to ambient noise in urban areas. Several studies already described the effect of weather conditions on the behavior of birds, but not the effect on song traits. We investigate, if song trait variability changes along a continuous urbanity gradient in Frankfurt am Main, Ge...
We investigated the karyotype of 18 didelphid species captured at 13 localities in the Brazilian Amazon, after conventional staining, C-banding, Ag-NOR and fluorescent in situ hybridization (FISH) using the 18S rDNA probe. Variations were found in the X chromosome, heterochromatin distribution and the 18S rDNA sequence. The main variation observed was in the position of the centromere in the X ...
Data on natural enemies of psyllids are rare and can usually be found in papers about economically significant species. During an investigation of psyllid fauna in Serbia, natural enemies were investigated, too. True bugs were the most numerous among them. From 28 psyllid species, 21 species of true bugs from families Anthocoridae and Miridae were reared. Seven species of Anthocoridae were iden...
Biological control has been reducing the use of chemical products against insect pests, especially predatory Pentatomidae. Species of this group can present high variations in their life cycle as a result of their diet. Thus, the objective of this research was to study nymph development and reproduction of Podisus distinctus (Stäl, 1860) (Heteroptera: Pentatomidae) fed on Bombyx mori L., 1758 (...
Over 5 years (2000-2004), populations of small mammals from a rural landscape in southern Moravia (Czech Republic) were investigated for the presence of Tula virus (TULV) antigen using the ELISA set Hantagnost. In total, 1566 individuals from 10 species were examined. The prevalence in the common vole (Microtus arvalis Pallas 1778), the main reservoir of TULV, was 10% (n = 871). The prevalence ...
The order of Pelecaniformes is composed of families Ardeidae (Leach, 1820), Thereskiornithidae (Poche, 1904), and Pelecanidae (Rafinesque, 1891) (CRBRO, 2011). The family Ardeidae gathers more than 60 species of herons, egrets and bitterns being one of the largest and more representative with characteristics adapted to wetlands (Sick, 1997). In the State of Rio Grande do Sul, 13 species are rec...
Agricultural activities can have a significant impact on aquatic organisms, including insects. Most of the Heteroptera are known as moderately tolerant to low oxygen and high nutrient concentrations. Nevertheless, complex effects agriculture (source both pesticides loads) this group still unclear. Therefore, relationship between six agricultural land use classes occurrence common bugs in Bulgar...
