Contrasting levels of polymorphism in cross-amplified microsatellites in two endangered xerothermophilous, obligatorily myrmecophilous, butterflies of the genus Phengaris (Maculinea) (Lepidoptera: Lycaenidae)
Aug 10, 2009; ... Key words. Lycaenidae, Phengaris arion, P. rebeli, genetic polymorphism, cross-amplification, Poland Abstract. We analysed the polymorphism of cross-amplified microsatellite loci in two endangered butterflies of the genus Phengaris, which inhabit warm grasslands. Specimens of P. arion ...
Origin of the complex karyotype of the polyploid parthenogenetic grasshopper Saga pedo (Orthoptera: Tettigoniidae)
Aug 10, 2009; ... Key words. Tettigoniidae, Saga pedo, chromosomes, DNA content, karyotype evolution, pentaploidy Abstract. Karyotypes of the polyploid parthenogenetic species Saga pedo from four localities in France and the Republic of Macedonia were constructed and compared. All these karyotypes consist ...
Interspecific variation in competitor avoidance and foraging success in sap-attracted insects
Aug 10, 2009; ... Key words. Aggressive interactions, community, foraging strategy, interference competition, resources, tree sap Abstract. Many insect species attracted to fermenting sap often fight for access to this resource, which results in the establishment of interspecific dominance hierarchies. In ...
Studies on the identity of the parasitoids Aphidius colemani and Aphidius transcaspicus (Hymenoptera: Braconidae)
Aug 10, 2009; ... Key words. Aphidius colemani, Aphidius transcaspicus, Aphidiinae, Braconidae, aphid parasitoids, cross mating, identification, molecular methods Abstract. The taxonomic status of the aphid parasitoid Aphidius colemani Viereck has been questioned, especially in regard to Aphidius ...
Down-regulation of gene expression between the diapause initiation and maintenance phases of the Colorado potato beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae)*
Aug 10, 2009; ... Key words. Chrysomelidae, Coleoptera, diapause, gene expression Abstract. The diapause initiation and maintenance phases of the Colorado potato beetle, Leptinotarsa decemlineata, were screened. Eight transcripts were found to be downregulated as the beetles enter the diapause maintenance ...
