BACKGROUND AND AIMS The phylogenetic relationships among 27 vetch species belonging to the subgenus Cracca of the genus Vicia were studied in comparison with three species of Lathyrus section Lathyrus on the basis of isozyme variation. METHODS Isozymes encoded by 15 putative loci of ten enzymes were resolved by polyacrylamide gel electrophoresis and isozyme variation was analysed by using par...

mites of family erythraeidae are parasites in their larval stage and predators in their post-larval stages on a variety of arthropods, among which are important pest species. during 2011-2013, in a faunistic survey of mites associated with beetles of the family chrysomelidae in oil and gas company of gachsaranregion, iran. specimens were preserved in ag (alcohol 75%, glyserin 5%), cleared in la...

Morphological differentiation of gall tissues induced on plants may play a role to characterize the real taxonomic position of the gall inducer. We verified this hypothesis with galls induced by Rectinasus buxtoni on Pistacia palaestina. There is controversy about the taxonomic localization of genus Rectinasus: in one classification it is situated with the genera Forda and Paracletus while in a...
