Alien phytophagous insect species on woody plants in park Maksimir

Istraživanje provedeno tijekom vegetacijske sezone 2012. godine je pokazalo da je na području parka Maksimir na drvenastom bilju udomaćeno 10 vrsta stranih biljojednih kukaca. To su sljedeće vrste: platanin moljac miner (Phyllonorycter platani), mrežasta platanina stjenica (Corythuca ciliata), kestenov moljac miner (Cameraria ohridella), brijestova osa listarica (Aproceros leucopoda), lipin moljac miner (Phyllonorycter issikii), moljac vrećastih mina bagrema (Phyllonorycter robiniella), bagremov moljac miner (Parectopa robiniella), bagremova muha šiškarica (Obolodiplosis robiniae), medeći cvrčak (Metcalfa pruinosa) i kestenova osa šiškarica (Dryocosmus kuriphylus). Rad prikazuje i osnovne značajke zabilježenih vrsta preuzete iz literature te podatke o razvojnim ciklusima i biologiji za sve vrste osim mrežaste platanine stjenice i kestenove ose šiškarice. Rad je obuhvatio i izračune intenziteta napada za lisne minere. Iako trenutno niti jedna vrsta ne uzrokuje značajniju štetu potrebno je obratiti posebnu pozornost problematici stranih vrsta kukaca u parku Maksimir jer su upravo takva urbana područja posebno osjetljiva na unos i širenje stranih vrsta.Research conducted during the growing season 2012. has shown there are 10 alien phytophagous species on woody plants in park Maksimir. These are the following: leaf blotch miner moth (Phyllonorycter platani), sycamore lace bug (Corythuca ciliata), horse chestnut leafminer (Cameraria ohridella), east asian sawfly (Aproceros leucopoda), lime leaf miner (Phyllonorycter issikii), black locust leaf miner (Phyllonorycter robiniella), locust digitate leaf miner (Parectopa robiniella), black locust gall midge (Obolodiplosis robiniae), citrus flatid planthopper (Metcalfa pruinosa) and oriental chestnut gall wasp (Dryocosmus kuriphylus). Basic features of the recorded species which are presented in this paper are taken from the literature. Paper also presents data on development cycles and biology of all species except sycamore lace bug and chestnut gall wasp, and calculations for the intensity of attacks for leaf miners. Currently, any of recorded species does not cause significant damage to trees in park Maksmir. Given the particular vulnerability of urban areas to the entry and spread of alien species we should pay particular attention to that issue in the park Maksimir
