Mosquito community structure on different habitats in Nature Park Kopački rit, Croatia

Research of mosquito community structure was conducted during a ten year period (1998-2008) between May and September in the Nature park Kopački rit, NE Croatia. Mosquitoes were collected with CO2 baited CDC-traps, once a month in four localities with three different plant communities: Čonakut and Kopačko Lake with white willow forest - Galio-Salicetum albae, Hordovanj with poplar forest - Populetum nigro-albae and Tikveš with old oak forest - Carpino betuli-Quercetum roburis. A total of 19 species were collected, belonging to 7 genera. Species dominance differed among habitats, but overall eudominant species are Aedes vexans (62, 83 %) and Anopheles maculipenis (12, 36 %). Old oak forest produced the greatest aggregation index, while white willow forest produced the lowest. Although in old oak forest the highest number of species was collected, diversity analysis showed that this forest had lowest values for diversity and evenness. This can be explained with high value of dominance index (ID=86, 32). Similarity indices indicate little difference between localities Čonakut, Hordovanj and Kopačko Lake, while Tikveš has a distinctly different community structure. All results clearly pointing to different mosquito species diversity and abundance in old oak forest.
