| seasonality, prevalence and pathogenicity of the gregarine ascogregarina taiwanensis (apicomplexa: lecudinidae) in mosquitoes from florida. | aedes albopictus larvae collected in gainesville, fl, were infected with the gregarine ascogregarina taiwanensis. natural prevalence varied from 68 to 100%. eight mosquito species were tested in the laboratory for susceptibility to a. taiwanensis isolated from field-collected ae. albopictus. aedes aegypti, aedes albopictus, and aedes taeniorhynchus became 100% infected in the larval stage, whereas aedes triseriatus was less susceptible; culex quinquefasciatus, culex nigripalpus, culex territans, ... | 1994 | 7807086 |
| parasitism of aedes aegypti and ae. albopictus (diptera: culicidae) by ascogregarina spp. (apicomplexa: lecudinidae) in florida. | aedes aegypti (l.) and ae. albopictus (skuse) from 40 sites in 17 counties of florida were surveyed for gregarine parasites during the spring and autumn of 1993 and in july 1994. larvae collected from containers (mainly tires) were dissected to determine the number of gregarine trophozoites present. ascogregarina spp. were found at 70% of the sites and occurred as frequently in ae. aegypti populations as in ae. albopictus. within sites, parasite distributions were highly variable and aggregated ... | 1995 | 8551508 |
| susceptibility of aedes aegypti and aedes albopictus larvae to ascogregarina culicis and ascogregarina taiwanensis (apicomplexa: lecudinidae) from florida. | the susceptibility of aedes aegypti to ascogregarina culicis and aedes albopictus to ascogregarina taiwanensis was examined with mosquito and parasite strains from tampa, fl. when each host was bioassayed with its natural gregarine, the infection intensity indicated that ae. aegypti was 59% more susceptible to a. culicis (87 gamonts/larva) than ae. albopictus to a. taiwanensis (47 gamonts/larva). infections in single and mixed host populations exposed to 100 oocysts/larva of one and both parasit ... | 2003 | 13678712 |
| aedes albopictus (diptera: culicidae): an experimental and natural host of dirofilaria immitis (filarioidea: onchocercidae) in florida, u.s.a. | females of an aedes albopictus (skuse) colony from southeastern florida, u.s.a., ingested low (22.9 +/- 3.2 mg/female) and high (243.2 +/- 37.6 mf/female) numbers of microfilariae from a dog infected with dirofilaria immitis (leidy). high mortality of females occurred during the first 4 d after infection regardless of the number of microfilariae ingested; daily mortality was almost negligible during 5-15 d after infection. percentage of survival 15 d after infection was higher (63%) in females t ... | 1999 | 10467770 |
| parasites of the asian tiger mosquito and other container-inhabiting mosquitoes (diptera:culicidae) in northcentral florida. | seven microorganisms including 4 protozoans, 2 fungi, and a bacterium infected aedes albopictus (skuse) larvae collected from 12 counties in northecentral florida. ae albopictus and 14 other species of mosquitoes were collected from tires, flower-holding vases in cemeteries, other types of artificial containers, and treeholes. ascogregarina taiwanensis (lien & levine) was the most common parasite of ae. albopictus throughout the year. the microsporidium vavraia culicis (weiser) infected aedes ae ... | 1997 | 9103767 |
