| [new data on the transmission of filariae]. | this paper summarizes research of the past several years on two phases of filarial transmission: the ingestion of microfilariae by the vector and the regulation of the percentage of successful parasites by the vector. experiments involved several different models for study: injection of inert particles into the bloodstream of a rodent and their subsequent ingestion by a vector; ingestion of gametocytes of different ages by vectors of a rodent malaria; and a monkey simultaneously infected with fo ... | 1985 | 3836764 |
| aedes aegypti: model for blood finding strategy and prediction of parasite manipulation. | aedes aegypti mosquitoes salivate during intradermal probing of vertebrate prey before ingesting blood (griffiths and gordon 1952). nonsalivating mosquitoes locate blood more slowly; this difference was ascribed to an anti-platelet activity found in the mosquito's saliva (ribeiro et al. 1984). mosquitoes infected with plasmodium gallinaceum suffer pathology that specifically impairs saliva anti-hemostatic activity but without reducing volume of output (rossignol et al. 1984). the complexity of t ... | 1985 | 3839460 |

| a simple method of identifying organophosphate insecticide resistance in adults of the yellow fever mosquito, aedes aegypti. | a simple filter paper spot test is described for identifying adult aedes aegypti resistant to malathion as a result of raised esterase levels. the method is compared with established polyacrylamide gel (pag) electrophoresis techniques for determining esterase-6 activity, and its applicability as a field test is discussed. | 1985 | 3880211 |
| laboratory evaluation of controlled-release insect repellent formulations. | seven microcapsule formulations and two polymer formulations of deet were tested on white rabbits for their repellency against the mosquito, aedes aegypti. two microcapsule formulations and one polymer formulation provided more than 80% protection for 12 hours. results demonstrated that the protection period of deet can be extended through controlled-release techniques. | 1985 | 3880224 |

| high-resolution gradient polyacrylamide electrophoresis of isozymes of the mosquito, aedes aegypti. | a procedure for high resolution electrophoresis of isozymes of the mosquito aedes aegypti using nonlinear (2.5%-20%) polyacrylamide gradient gel slabs is described. crude mosquito homogenates were electrophoresed on gradient and on homogeneous (7%) polyacrylamide gels and stained for esterase (est), isocitrate dehydrogenase (idh) and malate dehydrogenase (mdh). the resulting zymograms were compared to demonstrate the high resolving power of the polyacrylamide gradient gel system. | 1985 | 3880252 |
| location of esterase loci in aedes aegypti. | linkage relations of two loci, est-4 and est-6, have been studied in aedes aegypti. est-4 is on chromosome i, the sex chromosome, about 33 units from the sex region on the opposite side from red eye (re). this location is demonstrated for the first time. data for est-6 agree with results of other workers. | 1985 | 3880258 |
| the duration of larval life of aedes aegypti as affected by time of hatch. | when aedes aegypti eggs (1-10 wk old) were submerged in water, larvae that hatched in the 24 hr period following exposure to reduced oxygen developed significantly faster than larvae from the initial hatch. there were significant differences in the sex ratios between first- and second-hatch groups; however, adult size and fecundity did not differ significantly. | 1985 | 3880263 |
| development of dirofilaria immitis third stage larvae (nematoda: filarioidea) in micropore chambers implanted into surrogate hosts. | groups of 100 third stage larvae of dirofilaria immitis recovered from aedes aegypti were loaded into 250 microliters capacity micropore chambers (0.3 micron pore size) and implanted into the peritoneal cavity of mice, jirds, cotton rats and ferrets. in all hosts 74-87% of larvae moulted by 74 hours, with less than 5% mortality. the fourth stage worms recovered at 74 hours were cultured in vitro in l-15 (leibovitz) medium plus 20% foetal bovine serum with a dog sarcoma feeder cell line. after 96 ... | 1985 | 3890119 |

| isolation of a relatively nontoxic 65-kilodalton protein inclusion from the parasporal body of bacillus thuringiensis subsp. israelensis. | ultrastructural studies of the mosquitocidal bacterium bacillus thuringiensis subsp. israelensis revealed that the parasporal body contained three major inclusion types, designated types 1, 2, and 3, which could be differentiated on the basis of electron opacity and size and, to some extent, shape. the type-2 inclusion, which was of moderate electron density and often appeared as a bar-shaped polyhedral body, was isolated on nabr gradients from purified parasporal bodies and characterized by sod ... | 1986 | 3944061 |
| peptide nature of two mosquito natriuretic factors. | high-pressure liquid chromatography (hplc) of saline extracts of aedes aegypti heads yields three fractions (from a total of 108) that affect transepithelial voltage and/or fluid secretion in isolated aedes malpighian tubules. in this study we investigated the physical and chemical nature of the active materials in these fractions. gel-filtration chromatography revealed that the molecular weights of the three fractions were between 1,900 and 2,700. to test their thermostability the fractions wer ... | 1986 | 3953844 |
| increased biting rate and reduced fertility in sporozoite-infected mosquitoes. | because salivary function and blood location are impaired in sporozoite-infected mosquitoes, we determined whether such pathology also could lead to an increased biting rate. for 5 days, we compared relative daily biting rates of plasmodium gallinaceum sporozoite-infected mosquitoes (aedes aegypti) and noninfected mosquitoes with an olfactometer. mosquitoes then were exposed for 5 min to an anesthetized guinea pig. infected mosquitoes exhibited a significant increase in olfactometer response whi ... | 1986 | 3953943 |
| mechanical transmission of rift valley fever virus by hematophagous diptera. | experimental studies were conducted to determine if hematophagous diptera were capable of mechanical transmission of rift valley fever (rvf) virus to laboratory animals. all species tested (glossina morsitans, aedes aegypti, aedes taeniorhynchus, culex pipiens, stomoxys calcitrans, lutzomyia longipalpis, and culicoides variipennis) mechanically transmitted the virus to hamsters. mechanical transmission rates for g. morsitans ranged from 0-100%, with the probability of mechanical transmission pos ... | 1985 | 3970308 |
| plasmodium gallinaceum: sporozoite activity in immune mosquito hemolymph. | sporozoites of plasmodium gallinaceum are relatively inactive in hanks' balanced salt solution or in the hemolymph of the susceptible aedes aegypti mosquito. they become agitated and very active in the presence of the hemolymph of the innately immune mosquito, culex pipiens. sporozoites from the latter are more infective in chicks than the former. this behavior is likely the result of stimulation or irritation by the adverse environment. | 1985 | 3972059 |

| effect of selection for dichlorodiphenyltrichloroethane (ddt) resistance on the uptake and breakdown of ddt in aedes aegypti l. | aedes aegypti larvae and adults were selected to high levels of resistance with dichlorodiphenyltrichloroethane (ddt) along separate lines. the larval-selected line showed three responses associated with larval resistance: increased detoxication of ddt by dehydrochlorination to dichlorodiphenyldichloroethane dde (demonstrated both in vivo and in vitro), increased tolerance to unmetabolised ("residual") ddt and, a reduction in uptake of ddt. larval selection caused very little change in adult res ... | 1985 | 3986671 |
| hormone-mediated formation of the endocytic complex in mosquito oocytes. | the developmental events leading to oocyte competence to internalize proteins, and the hormonal control of these events in the mosquito aedes aegypti have been studied. the oocytes of newly eclosed females have an undifferentiated cortex. during previtellogenic development, a highly specialized endocytic complex, consisting of numerous coated vesicles and uncoated endosomes, microvilli, and, presumably, vitellogenin receptors, forms in the oocyte cortex. morphometric analysis and probes with a p ... | 1985 | 3988025 |

| analysis of lipids by gas-liquid chromatography and complementary methods in four strains of aedes aegypti mosquitoes. | fatty acid composition of total lipids, neutral lipids and phospholipids of strains of aedes aegypti were determined. the fatty acid composition of the strains differed quantitatively with regard to the relative percentage of commonly occurring fatty acids. gas-liquid chromatography of fatty acid methyl esters showed 18:1 (oleic or elaidic) to be the predominant fatty acid. the fatty acid was identified as oleic by argentation thin-layer chromatography. a modified colorimetric method was used to ... | 2013 | 4017543 |
| bioassays of bacillus sphaericus (strain 1593) against mosquitoes of public health importance in malaysia. | the pathogenicity of bacillus sphaericus strain 1593 was tested against laboratory-reared larvae of four local species of mosquitoes of public health importance in malaysia; aedes aegypti, anopheles balabacensis, mansonia uniformis and culex quinquefasciatus. the bacteria was shake-cultured at 28 +/- 1 degrees c for three days, using glucose-yeast extract salts medium. after which, the spores and vegetative cells were harvested and stored at 4 degrees c before use. conditions for bioassays were ... | 1985 | 4023816 |
| argentophilic structures of spermatogenesis in the yellow fever mosquito. | application of the silver-staining technique to air-dried chromosome preparations of the yellow fever mosquito, aedes aegypti, revealed the following: 1) intensely stained pericentromeric regions in all chromosomes including the y chromosome in spermatogonia, and during the primary and secondary spermatocytes; 2) the presence of prepachytene that were not reported earlier; 3) a nucleolus organizing region that persisted up to the late pachytene stage; and 4) rod or ring-like centrioles in pachyt ... | 2006 | 4031466 |
| transition from somatic to meiotic pairing and progressional changes of the synaptonemal complex in spermatocytes of aedes aegypti. | aedes aegypti spermatocytes were reconstructed from electron micrographs. the species has tight somatic pairing of the chromosomes, and there are therefore no classical leptotene and zygotene stages, but rather a gradual transition from somatic pairing to meiotic pairing (= pachytene). the term "prepachytene" has been used for the transitory stage. the first visible sign of impending meiosis was a reorganization of the chromatin, which resulted in the formation of spaces (synaptic spaces) in the ... | 1985 | 4042770 |

| [effect of mosquito contact with ddt and their susceptibility to the causative agent of malaria]. | the contact of aedes aegypti mosquitoes with ddt one hour prior to the infectious feeding results in a slight decrease of their susceptibility to plasmodium gallinaceum. the contact 24 hours prior to the infectious feeding does not affect the susceptibility of mosquitoes. | 1985 | 4047719 |
| ultrastructure of midgut endocrine cells in the adult mosquito, aedes aegypti. | the ultrastructure of endocrine cells in the midgut of the adult mosquito, aedes aegypti, resembled that of endocrine cells in the vertebrate gastro-intestinal tract. midgut endocrine cells, positioned basally in the epithelium as single cells, were cone-shaped and smaller than the columnar digestive cells. the most distinctive characteristic of endocrine cells was numerous round secretory granules along the lateral and basal plasma membranes where contents of the granules were released by exocy ... | 1985 | 4060146 |
| dengue and hepatic failure. | dengue hemorrhagic fever/dengue shock syndrome is a serious manifestation of dengue fever, which is observed predominantly in the tropical regions of the west pacific and in southeast asia and is associated with secondary infections, mainly in children under age 15. a concomitant microangiopathic coagulopathy has been described; moreover, encephalopathy and even reye's syndrome have been rarely reported. this report describes a 51-year-old man with secondary dengue infection who presented with c ... | 1985 | 4061482 |
| egg maturation and ecdysiotropic activity in extracts of mosquito (aedes aegypti) heads. | blood-fed, decapitated female aedes aegypti mosquitoes matured eggs when injected with an extract of heads, but non-blood-fed females did not. the response to head extract was optimal when the head was allowed to remain for 2 hr after feeding. a dose response to injected egg development neurosecretory hormone (ednh) was observed in vivo that was similar to in vitro dose responses previously reported. blood-fed decapitated females responded equally well to boiled or unboiled head extract. when bl ... | 1985 | 4065529 |

| laboratory colonization of toxorhynchites brevipalpis. | toxorhynchites brevipalpis, a predator on larvae of aedes aegypti and other mosquitos, was successfully colonized in the laboratory. at 25 degrees c, embryonic development was completed within 50 hours of oviposition, while larval and pupal development together took a further 27-41 days. the adult mosquitos mated in cages as small as 15x15x15 cm, and the embryonated eggs were obtained 6-31 days after the adults emerged. | 1973 | 4149530 |
| adult population estimate of toxorhynchites brevipalpis. | an estimate of the numbers of adults of the predacious mosquito toxorhynchites brevipalpis was made in a 1-ha biotope in dar es salaam, tanzania, where the population of its larval prey aedes aegypti was high, by means of the mark-release-recapture method. two months after the end of the rainy season, the number of adults was estimated to be 3 500-about 6 times the number of adult a. aegypti in the biotope. | 1973 | 4150432 |
