ABSTRACT
The aim of the present study was to evaluate, qualitatively and quantitatively, the galls forming by wasps (Hymenoptera, Cynipidae) on oaks and aphids (Hemiptera, Aphididae, Eriosomatinae) on elms in the Lublin region. Besides, a state of knowledge on galls formation as an effect of insect feeding and their effect on host plants are presented. The studies were carried out during three vegetation seasons in 2009–2011 in the habitats of different anthropopressure. As a result of the study the occurrence of galls induced by 11 cynipid species on oaks and 2 aphid species on elms was examined. On oaks high intensity of occurrence was in the case of galls caused by both generations of Neuroterus quercusbaccarum (L.) and by asexual generation of N. numismalis (Fourc.) as well as Cynips quercusfolii (L.). Relatively medium intensity of occurrence was observed for galls of the sexual generation of A.inflator (Hartig) on Q. robur ‘Fastigiata’. So far this gall-forming wasp has not been observed in the Lublin region. On elms high abundance of Tetraneuraulmi (L.) galls was noted.
Key words: galls, Cynipidae, Aphididae, gall formation, elm, oak.
