Aphids (Hemiptera: Aphidinea) and ground beetles (Coleoptera: Carabidae) in the urban environments of Bydgoszcz and its vicinities
2013, 14 (1) p. 157-168
The subject of this study was aphids (Hem., Aphidinea) in particularly valuable environments called “environmental islands”. In fact, they are specific refuges of beneficial and protected entomofauna in the agricultural landscape. The results can contribute to verification of protection of some arable crops by taking those habitats into consideration in the so-called natural biological pest control. Towns, in turn, are specific ecosystems which are composed of many factors with a clearly different character and intensity than in natural environments. On account of the important role and a small degree of knowing Carabidae fauna in urbanized areas, a study was undertaken in 1998 in Bydgoszcz and its neighbourhood, aimed at indicating hanges that occur in the fauna of Carabidae in various types of urban green and town protection zone, as well as determining the role of these environments as reservoirs of entomophagous species, which can disperse to agrocenoses.
