| efficacy of two formulations of bacillus thuringiensis var. israelensis (h-14) against aedes vexans and safety to non-target macroinvertebrates. | an experimental sandoz formulation of bacillus thuringiensis var. israelensis (san 402 sc 98) was several times more effective than abbott abg 6188 against larvae of aedes aegypti and ae. vexans in the laboratory. field applications of san 402 sc 98 at 0.25 liter/ha and abg 6188 at 1.00 liter/ha resulted in more than 97% control of ae. vexans larvae after 48 hours, with residual activity of 24 hours or less. the amphipod, hyallela azteca, and 4 species of water beetles were apparently unaffected ... | 1988 | 3199115 |

| bloodmeal sources of aedes triseriatus and aedes vexans in a southern wisconsin forest endemic for la crosse encephalitis virus. | the micro enzyme-linked immunosorbent assay (elisa) was used to specifically identify bloodmeal sources of aedes triseriatus say and aedes vexans meigen collected at a site endemic for la crosse (lac) encephalitis virus. deer were the source of 65% of ae. triseriatus and 94% of aedes vexans bloodmeals, respectively. chipmunks and tree squirrels, which are considered to be the major vertebrate amplifying hosts of lac virus, were the sources of 8% and 16%, respectively, of the bloodmeals of ae. tr ... | 1982 | 7072901 |
| records of mosquito-parasitic mermithid nematodes in the northcentral united states. | mermithid parasites (nematoda: mermithidae) were observed in 11 mosquito species in 22 counties of indiana, michigan, minnesota, ohio and wisconsin. natural hosts included adult aedes vexans, ae. canadensis, ae. cinereus, ae. diantaeus, ae. punctor, anopheles punctipennis and coquillettidia perturbans and larvae of ae. abserratus, ae. canadensis, ae. cinereus, ae. communis, ae. diantaeus, ae. provocans, ae. punctor, ae. stimulans and cq. perturbans. these are the first records of such parasites ... | 1993 | 7902415 |
| mosquito surveillance for west nile virus in southeastern wisconsin--2002. | in 2001, west nile virus (wnv) was identified among dead american crows and bluejays in five counties in southeastern wisconsin. in response to the introduction of wnv, a pilot mosquito surveillance program was initiated in these five southeastern wisconsin counties during the summer of 2002. forty sites were selected for surveillance one night each week during a 17-week period. mosquitoes were collected in carbon dioxide-baited light traps and gravid traps. during the study period 31,419 mosqui ... | 2003 | 15931283 |
