| vector competence of mosquitoes as a marker to distinguish central american and mexican epizootic from enzootic strains of venezuelan encephalitis virus. | two epizootic strains of venezuelan encephalitis (ve) virus from central america and mexico were transmitted by a colonized epizootic vector mosquito, aedes taeniorhynchus, at higher rates than were two enzootic strains when the mosquitoes were infected by intrathroacic inoculation or feeding of virus. differences in transmission rates also occurred with colonized aedes aegypti, but were less marked. following intrathoracic inoculation of a. taeniorhynchus or a. aegypti, epizootic strains grew t ... | 1976 | 1259093 |
| transmission of venezuelan equine encephalomyelitis virus by aedes sollicitans and aedes taeniorhynchus (diptera: culicidae). | experimental studies compared the vector competence of aedes sollicitans (skuse) and ae. taeniorhynchus (wiedemann) collected on assateague island, va., for an epizootic strain (trinidad donkey) of venezuelan equine encephalomyelitis (vee) virus. infection rates were significantly higher in ae. sollicitans (101/107, 94%) than in ae. taeniorhynchus (103/175, 59%), even though both species fed concurrently on the same infected hamsters. similarly, dissemination and transmission rates were signific ... | 1992 | 1552530 |
| eggshells as an index of aedine mosquito production. 1: distribution, movement and sampling of aedes taeniorhynchus eggshells. | the distribution of aedes taeniorhynchus eggshells in florida mangrove basin forests was determined and used to design a sampling plan. eggshells were found in 10/11 sites (91%), with a mean +/- se density of 1.45 +/- 0.75/cc; density did not change significantly year to year. highest densities were located on the sloping banks of hummocks, ponds and potholes. eggshells were less clumped in distribution than eggs and larvae and thus required a smaller sample size for a given precision level. whi ... | 1992 | 1583486 |
| eggshells as an index of aedine mosquito production. 2: relationship of aedes taeniorhynchus eggshell density to larval production. | to test if eggshell density could be used as an index of aedine mosquito production, we compared eggshell density with the larval production of aedes taeniorhynchus in florida mangrove basin forests. quantitative (n = 7) and categorical (n = 34) estimates of annual larval production were regressed against the number of eggshells per cc of soil. significant regressions were obtained in both instances. larval production was concentrated in zones with the highest eggshell density. we suggest that e ... | 1992 | 1583487 |
| comparison of the synthetic pyrethroids esbiothrin and bioresmethrin with scourge and cythion against adult mosquitoes in a laboratory wind tunnel. | both candidate adulticides, esbiothrin and bioresmethrin, exhibited quick knockdown 1-h posttreatment. esbiothrin elicited the fastest knockdown, but bioresmethrin was more effective at both 1- and 24-h posttreatment than either esbiothrin or scourge against both aedes taeniorhynchus and culex quinquefasciatus. mosquitoes treated with scourge required more time and a higher dosage to respond in a physiological manner similar to those treated with either of the candidate adulticides. more than tw ... | 1992 | 1583490 |
| the killifish rivulus marmoratus: a potential biocontrol agent for aedes taeniorhynchus and brackish water culex. | in the laboratory, newly hatched fry of rivulus marmoratus were effective predators on 1st-instar aedes taeniorhynchus. adult fish consumed 4th-instar ae. taeniorhynchus and egg rafts of culex quinquefasciatus at a rate increasing with standard length of the fish. predation of rivulus marmoratus on ae. taeniorhynchus larvae in the field was documented by observing the passage of larval/pupal remains through the gut. laboratory reared fish released at known ae. taeniorhynchus breeding sites survi ... | 1992 | 1583495 |
| control of aedes taeniorhynchus and culex quinquefasciatus emergence with sustained release altosid sand granules and pellets in saltwater and freshwater test plots. | the efficacy of sustained release altosid sand granules to control adult aedes taeniorhynchus and culex quinquefasciatus emergence was investigated. sand granules applied at a 7-day preflood application rate of 5.6 kg/ha controlled 99% of the ae. taeniorhynchus emergence in saltwater plots for 44 days posttreatment and 35% of cx. quinquefasciatus in freshwater plots. a 5.6 kg/ha rate controlled 100% of the ae. taeniorhynchus emergence for 30 days posttreatment in semi-permanent saltwater plots. ... | 1991 | 1791449 |
| [the pilot project results of applications of the biolarvicide bacillus sphaericus 2362 on mosquito breeding grounds of the town of santa cruz del norte (la habana province)]. | the effectiveness of the bacillus sphaericus strain 2362 in liquid formulation, at a 10 ml/m2 dose, was tested in 157 breeding sites of culex quinquefasciatus mosquitos, 2 breeding sites of culex quinquefasciatus and anopheles albimanus and 1 breeding site of aedes taeniorhynchus, consisting of 1 river, 2 oxidation ponds, 1 pond, 4 dams, 2 microdams and 150 pits. the results reached with the application of 1800 1 of biolarvicide show its effectiveness. within 24 hours of treatment, mortality rat ... | 1991 | 1801088 |
| interactive effects of 1-octen-3-ol and carbon dioxide on mosquito (diptera: culicidae) surveillance and control. | responses of natural populations of biting diptera were studied at everglades national park, fla., to three levels (0, 3.0, and 41.1 mg/h) of 1-octen-3-ol (octenol), four levels (0, 20, 200, and 2,000 ml/min) of carbon dioxide (co2), and their combinations. catches of mosquitoes (aedes taeniorhynchus (wiedemann), culex [melanoconion]) spp., cx. nigripalpus theobald, and wyeomyia spp.) and one tabanid (diachlorus ferrugatus (f.)) were affected significantly by co2 and octenol. significantly great ... | 1999 | 1905355 |
| aedes taeniorhynchus (diptera: culicidae) oviposition patterns in a florida mangrove forest. | the association of aedes taeniorhynchus eggs and several variables was studied in a florida mangrove forest. eggs were limited to stands of red mangrove (rhizophora mangle l.) that were embedded within a black mangrove (avicennia germinans l.) forest. the occurrence of eggs was related significantly to elevation and the amount of detritus. field and laboratory studies indicated that grazing on black mangrove detritus by the snail melampus coffeus l. may have limited detritus accumulation and soi ... | 1991 | 1941908 |
| field studies on the potential of butanone, carbon dioxide, honey extract, 1-octen-3-ol, l-lactic acid and phenols as attractants for mosquitoes. | various combinations of six candidate attractants--butanone, carbon dioxide (co2), honey, octenol, lactic acid and mixed phenols--were tested against natural populations of mosquitoes in everglades national park, florida, u.s.a., using unlighted cdc-baited traps. with few exceptions, the attractancy of these candidate compounds to mosquitoes, when used alone, was less than that of co2 alone. the exceptions were that octenol and honey extract alone attracted larger numbers of coquillettidia pertu ... | 1990 | 1983456 |
| collection and separation of aedes taeniorhynchus eggshells from mangrove soil. | two methods to separate eggshells of aedes taeniorhynchus from mangrove soil were compared. selective sieving, using nested sieves with 0.185 and 0.170-mm screen openings, and water flotation both removed over 99% of the soil. however, water flotation recovered a significantly greater percentage of eggshells (62% vs. 34%). there was no significant difference in the recovery rate of viable eggs and new and old eggshells using water flotation. | 1991 | 2045802 |
| poor vector efficiency of culex quinquefasciatus following infection with dirofilaria immitis. | the vector efficiency of the haiti and covington strains of culex quinquefasciatus after feeding on dog blood infected with dirofilaria immitis (approximately 110 microfilariae (mf)/20 microliters of blood) was 1.2 and 0.3%, respectively, versus nearly 20% for the vero beach strain of aedes taeniorhynchus. at a much higher microfilaremia (approximately 400 mf/20 microliters), it was 1.6, 0.5 and 31.5%, respectively. the poor vector efficiency of the 2 cx. quinquefasciatus strains probably was du ... | 1991 | 2045806 |
| distribution and sampling of aedes taeniorhynchus (diptera: culicidae) eggs in a florida mangrove forest. | the distribution of aedes taeniorhynchus (wiedemann) eggs in a florida mangrove basin forest was quantified and used to design a sampling plan. eggs were found in detritus-rich soil with the highest densities in a band at elevations 0.1-0.2 m above the water line. dispersion indices (k and taylor's b) indicated that the eggs were aggregated; 14 of 16 populations tested fit the negative binomial distribution. a fixed-size sampling plan using systematic sampling was designed from these data. | 1991 | 2056510 |
| integrated use of planaria (dugesia dorotocephala) and bacillus thuringiensis var. israelensis against aedes taeniorhynchus: a laboratory bioassay. | the effectiveness of integrating bacillus thuringiensis var. israelensis (b.t.i.) and the predatory planaria, dugesia dorotocephala against aedes taeniorhynchus was determined under controlled laboratory conditions. there was no significant effect (p greater than 0.05) of b.t.i. on d. dorotocephala either by direct association or through ingestion of b.t.i. dosed larvae. planaria, alone, and b.t.i. combined with planaria, both provided significant (p less than 0.05) reduction of ae. taeniorhynch ... | 1990 | 2098475 |
| effects of controlled burning on aedes taeniorhynchus eggs in an abandoned rice impoundment in south carolina. | controlled burning reduced the number of viable eggs in an aedes population. the effectiveness of the burn was related to the amount of rainfall, surface moisture and dry vegetation. a greater reduction in viable eggs occurred when the burn was close to the ground. variable results were achieved if the surface was moist but there was a significant reduction in the number of viable eggs, due to a heavy amount of dry vegetation accompanied by low rainfall. | 1990 | 2230784 |
| small plot test of sustained-release altosid (methoprene) pellets against aedes taeniorhynchus in brackish water. | four percent methoprene pellets applied at a rate of 2.2 kg/ha effectively controlled adult aedes taeniorhynchus emergence (93%) for over 3 weeks. efficacy declined to 38% 4 weeks posttreatment. at a rate of 4.5 kg/ha, 95% control was maintained for 34 days with the exception of the 5th week when only 72% control was observed. | 1990 | 2324717 |
| a simulation model of water depth in mangrove basin forests. | the construction and validation of a model simulating the water depth within mangrove basin forests is described. rainfall, water table, water depth and tide data collected from a red mangrove basin forest on marco island, fl, was used to estimate model parameters. these included the basin spillover height, evapotranspiration-infiltration rate and the functional relationship of water depth change to rainfall, tide and basin spillover. the model was constructed with lotus 123 and calibrated from ... | 1990 | 2370528 |
| nectar-feeding habits of aedes taeniorhynchus. | aedes taeniorhynchus were collected on the wing at several times during the day and night, in indian river and brevard county, florida. nonblooded females were individually analyzed for fructose and glycogen. fructose content of mosquitoes collected early in the morning and held without food during the day diminished to approximately the same level as in mosquitoes collected late in the afternoon. however, fructose content of mosquitoes collected before sunset and held without food overnight dim ... | 1990 | 2370536 |
| current status on the florida abate monitoring program--susceptibility levels of three species of mosquitoes during 1984. | during 1984, larval susceptibility tests of temephos were performed on aedes taeniorhynchus and culex nigripalpus collected from the same general areas as in 1980-82, and the results compared to the susceptible laboratory strains. no resistance was detected against these two species. when strains of culex quinquefasciatus from some new areas were tested against temephos, malathion, naled, fenthion and chlorpyrifos, their tolerance varied according to the insecticide tested and the origin of the ... | 1985 | 2466107 |
| chronic pruritic eruption in patients with acquired immunodeficiency syndrome associated with increased antibody titers to mosquito salivary gland antigens. | five of seven patients with acquired immunodeficiency syndrome (aids) who had pruritus and a chronic, nonspecific-appearing skin eruption had increased antibody titers to antigens in the salivary glands of aedes taeniorhynchus, a salt marsh mosquito common to south florida. we hypothesize that the pruritus and skin lesions in patients with aids represent a form of chronic "recall" reaction. increased antibody titers to mosquito salivary gland antigens may be a consequence of nonspecific b cell a ... | 1989 | 2569000 |
| carbon dioxide and 1-octen-3-ol as mosquito attractants. | interval suction traps were used to study the attractant effect of co2 and 1-octen-3-ol on trap catches of mosquito populations at 2 different locations in florida. there was no significant increase in the numbers of mosquitoes caught when the concentration of co2 was increased from 200 to 1,000 cc/min. one-octen-3-ol used by itself attracted mosquitoes in numbers similar to co2 released at 200 cc/min. one-octen-3-ol and co2 acted synergistically in attracting significantly greater numbers of ae ... | 1989 | 2573687 |
| fluid secretion and microvillar ultrastructure in mosquito malpighian tubules. | the malpighian tubules of fourth instar larvae, pupae, and female adults of the mosquito aedes taeniorhynchus were examined with regard to in vitro fluid secretion rate and the ultrastructural features of the microvillar border of the primary cells. in vitro fluid secretion rates were determined after stimulation with 5-hydroxytryptamine. while larval tubules are capable of rapid fluid secretion, the tubules of pupae exhibit very low rates of secretion, indistinguishable from 0 nl/h. the capacit ... | 1989 | 2589535 |
