Abstract

The vertical distribution of adult mosquitoes was studied in southern(Norra Angstrom sum) and central Sweden (Tarnsjo) during August 1995,with an emphasis on the ornithophilic species Culiseta morsitans (Theobald), Culex pipiens L., and Culex torrentium Martini. A modified slingshot method was used to suspend Centers for Disease Control (CDC) miniature light traps, in combination with CO, as additional attractant,into the canopy of deciduous trees. Altogether 15,186 mosquitoes, including 93 Cs. morsitans and 182 Cx. pipiens/torrentium, were collectedat various heights above ground during 43 trap-nights. The numbers ofCs. morsitans and Cx. pipiens/torrentium per trap-night were not significantly influenced by height, but the number of total mosquitoes pertrap-night decreased with increasing height. Significantly larger proportions (alpha<0.001, chi-square test) of both Cs. morsitans and Cx. pipiens/torrentium, to the total of other mosquitoes, were collected in the canopy than at chest height. The proportions of Cs. marsitans were 18% at 12 to 15.5 m and 2.2% at 1.5 m in Norra Angstrom sum, and 49% at 14 to 18 m and 0.6% at 1.5 m in Tarnsjo. The proportions of Cx. pipiens/torrentium were 36% at 12 to 15.5 m and 6.9% at 1.5 m in Norra Angstrom sum, and 5.1% at 6 to 9m and 0.2% at 1.5 m in Tarnsjo. Our method of suspending traps in the canopy and use of a simplified protocol to quickly distinguish the relevant species was efficient for placing the traps and for sampling adult females of the ornithophilic species Cx. pipiens/torrentium and Cs. morsitans in Sweden. We suggest that this procedure might also be of use to investigate these and other ornithophilic mosquitoes for bird-associated arboviruses in woodlands in the European region.
