| isolations of potosi virus from mosquitoes (diptera: culicidae) collected in connecticut. | potosi virus (potv) (bunyaviridae: orthobunyavirus) was first isolated from aedes albopictus (skuse) collected in potosi, mo, in 1989, and subsequent isolations were reported from illinois, michigan, ohio, and the carolinas. to determine whether the distribution of this virus extends into the northeastern united states, we analyzed arboviruses acquired from mosquitoes collected in connecticut from 1998 to 2004. in 2001, a bunyavirus was isolated from aedes vexans (meigen) that was different from ... | 2005 | 16363172 |

| simultaneous field comparison of evening temporal distributions of nectar and blood feeding by aedes vexans and ae. trivittatus (diptera: culicidae) in ohio. | nectar- and blood-feeding time distributions of aedes vexans (meigen) and aedes trivittatus (coquillett) were determined from collections of mosquitoes attempting to feed on flowers and human bait during six nights in an ohio field. distributions of nectar and blood feeding were different in ae. vexans on three of five nights when analyses were possible, and they were different in pooled ae. trivittatus data. higher proportions of blood feeders appeared in earlier time intervals, but both nectar ... | 1992 | 1495059 |
