| differential distribution of peridomestic aedes mosquitoes on grand bahama island. | aedes aegypti, on grand bahama island, is restricted to certain western towns, whereas a. bahamensis is more generally distributed. during 14 years of observation, the range of a. aegypti has extended 8 km and now includes the major tourist centre. relocation of discarded automobile tires is an important mechanism for such spread. we suggest that the presence of a. bahamensis restrains colonization by a. aegypti, and thereby helps to protect human populations from a. aegypti-borne disease. | 1979 | 555063 |

| topical mosquito repellents xiii: cyclic analogs of lactic acid. | numerous cyclic analogs of lactic acid were synthesized to ascertain whether they might act as agonists of antagonists of lactic acid, a known attractant for mosquitoes. these compounds were evaluated with an in vitro blood-feeding test system and an in vivo cloth test. two of the compounds in the blood-feeding test system showed biphasic results, acting as attractants at low concentrations and as repellents at higher concentrations. several compounds (iii, v, vii, and x) repelled aedes aegypti ... | 1980 | 7359323 |
| the mosquito aedes aegypti (l.): evidence for three new proteinases. | the effect of inhibitors was studied on the proteolytic activity of crude extracts of the mosquito aedes aegypti (l.), prepared 25 h after blood intake. this activity is only partially inhibited by the lima bean trypsin inhibitor (lbti) or by edta. experiments with mixed inhibitors are used to indicate that, apart from the well characterized trypsin-like enzymes, at least three other proteinases are present. these are an lbti-resistant serine proteinase, a metal chelator-sensitive proteinase, an ... | 1980 | 6245543 |
| the measurement of blood meal size in aedes aegypti (l.). | three techniques of estimating blood meal volumes (gravimetric, radioisotope counting and haemoglobin estimation) were compared in adult female aedes aegypti fed on a cat. aedes aegypti ingested a mean volume of 2.37 ul, 2.44 ul and 2.57 ul as measured by gravimetric, radioisotope and haemoglobin estimation techniques respectively. this difference was not statistically significant (p greater than 0.05, n = 58). neither calendar age (post-eclosion) nor strain differences appear to influence blood ... | 1980 | 6282090 |
| chemically-defined media for production of insect cells and viruses in vitro. | two chemically-defined media are described. they support the growth of a) an established cell line of spodoptera frugiperda cells and b) two established mosquito cell lines from aedes aegypti and anopheles gambiae. the replication of autographa californica nuclear polyhedrosis virus (acnpv) in s. frugiperda cells grown in a defined medium is reported. | 1980 | 6102531 |
| dengue hemorrhagic fever in malaysia: the 1973 epidemic. | the first major malaysian epidemic of dengue hemorrhagic fever with severe manifestations occurred in 1973, with 969 reported cases and 54 deaths. in a detailed study of 138 clinically diagnosed and laboratory confirmed cases at the general hospital in kuala lumpur, hemorrhagic manifestations were observed in 68.7% and shock in 18.1% of the patients. the cases occurred mainly from may to september, largely in urban and suburban areas of the majority of the states in the country. a main focus of ... | 1980 | 6105712 |
| potential vectors of malaria and dengue at townsville, queensland. | a biting collection on the banks of ross river included anopheles farauti, adedes imprimens and ae. alboscutellatus, indicating a relict population of rain-forest mosquitoes and confirming two earlier records of an. farauti from townsville. aedes aegypti was collected at townsville airport. significance of these findings is discussed in relation to changing urban conditions and a proposed international airport. | 1980 | 6111741 |
| transovarial transmission of yellow fever virus in stegomyia mosquitoes. | transovarial transmission of two strains of yellow fever virus was demonstrated in three colonized geographical strains of aedes aegypti following infection by intrathoracic inoculation. infected progeny were detected in f1 offspring from only the first three ovarian cycles (ovc). the overall minimum filial infection rate for the first three ovc was 1:596; rates were loser in the second and third ovc. virus survived in eggs for longer than 4 months and was recovered from progeny of three immersi ... | 1980 | 6766282 |
| dengue-2 vaccine: viremia and immune responses in rhesus monkeys. | studies were undertaken in indian rhesus monkeys (macaca mulatta) to determine the safety, potency, immunogenicity, and mosquito infectivity of a small-plaque, temperature-sensitive variant of dengue type 2 (den-2) virus, a vaccine candidate. fifteen monkeys were inoculated subcutaneously with the vaccine virus, ten receiving 10(3.1) plaque-forming units (pfu) and five receiving 10(4.5) pfu. after primary immunization, viremia was detected in only one monkey, a recipient of the higher dose of va ... | 1980 | 6766903 |
| anti-gamete monoclonal antibodies synergistically block transmission of malaria by preventing fertilization in the mosquito. | experiments from our laboratory previously demonstrated that infected chickens immunized with gametes of the avian malaria parasite plasmodium gallinaceum were no longer infectious to the mosquito vector aedes aegypti and that this transmission-blocking immunity was mediated by antibody. to identify those antigens that are the targets of transmission-blocking immunity, hybrid mouse cell lines secreting monospecific antibodies to surface antigens on male and female gametes of p. gallinaceum have ... | 1980 | 6935685 |
| dengue haemorrhagic fever--a public health problem and a field for research. | dengue haemorrhagic fever/dengue shock syndrome (dhf/dss) is an enigmatic and growing public health problem which is confined at present to countries of south-east asia. since 1956, over 350 000 patients have been hospitalized and nearly 12 000 deaths have been reported. dengue viruses, a group of four flaviviruses, are transmitted to man by aedes aegypti. currently, dengue viruses are actively transmitted in 61 countries which circle the globe in the tropical zone and have a combined population ... | 1980 | 6966540 |

| utilization and metabolism of dietary sterols in the honey bee and the yellow fever mosquito. | the honey bee, apis mellifera, does not convert c28 and c29 phytosterols to cholesterol as found in most previous studies of phytophagous or omnivorous insects, but instead the workers and queens selectively transfer 24-methylenecholesterol, sitosterol and isofucosterol from their endogenous sterol pools to the brood larvae regardless of the sterol in the worker diet. administering radiolabeled sterols by feeding and injection has made it possible to trace this selective transfer through a secon ... | 1982 | 7087696 |
| allelochemics produced by the hydrophytemyriophyllum spicatum affecting mosquitoes and midges. | an extract of the hydrophytemyriophyllum spicatum l. was found to be toxic to first- and fourth-instar larvae of the mosquitoes,culex quinquefasciatus say,culex tarsalis coquillett,culiseta incidens (thomson),aedes aegypti l., and chironomid midges in the laboratory. when first-stage larvae were exposed to the extract, the lowest concentration (6.4 mg extract/100 ml h2o) produced 86,60, and 48% mortality inc. incidens, c. quinquefasciatus, anda. aegypti, respectively. higher concentrations cause ... | 1982 | 24414962 |

| comparative bioassays of bacillus thuringiensis h-14 formulations against four species of mosquitoes in malaysia. | comparative laboratory bioassays of three formulations of bacillus thuringiensis h-14 (ips-78, san 402-i and bactimos) were conducted against late 3rd/early 4th instar larvae of four species of mosquito, viz., aedes aegypti, culex quinquefasciatus, anopheles balabacensis and mansonia (mansonioides) indiana, in malaysia. from the average response of the mosquito larvae to the three formulations of b. thuringiensis h-14, ae. aegypti was found to be most susceptible, followed by cx. quinquefasciatu ... | 1982 | 6128794 |
| the effects of parabiotic twinning of susceptible and refractory mosquitoes on the development of plasmodium gallinaceum. | two species of mosquitoes were joined parabiotically with glass capillaries so as to share common hemolymph. in experiments designed to determine optimum physical factors was found that capillaries of 2.5 mm in length, 100 microns od and with pointed ends were tolerated best by mosquitoes and permitted optimum hemolymph transfer. maximum survival of mosquitoes was noted when capillaries were inserted in the post mesospiracular membranous area, in the largest mosquito first and allowed to fill wi ... | 1982 | 6129293 |

| host behaviour and mosquito feeding success: an experimental study. | the susceptibility of laboratory rabbits to attack by mosquitoes (aedes aegypti) is found to be closely linked to their grooming activity. prevention of grooming significantly increases both the percentage of mosquitoes feeding and the size of blood meals. grooming responses intensify with parasite density, and lead to a slight decline in parasite feeding success and blood meal size. grooming efficiency varied between individual rabbits and also a consequence of experience, with rabbits improvin ... | 1982 | 7080144 |
| the infectivity of microfilariae of brugia pahangi of different ages to aedes aegypti. | by transferring microfilariae of brugia pahangi which had been born over a 24-hour period in the peritoneal cavities of jirds (meriones unguiculatus) to the blood circulation of other jirds, infections of known age were tested for their ability to develop into third-stage larvae (l3) in mosquitoes aedes aegypti. microfilariae less than three days old were not able to develop to l3. microfilariae which had been in circulation for three days to six months were capable of developing if ingested. | 1982 | 7096971 |
