haemolytic activity in the blood clot of aedes aegypti.in the present study it was demonstrated that mosquito blood clots contain a haemolytic principle which achieves haemolysis of washed erythrocytes in an isotonic medium. proteinases are thought to play a role in this process. no final proof could be given for the existence of phospholipase activity although some results suggest the presence of this group of enzymes.1975240259
the esterase patterns in the ovaries and the embryonated eggs of aedes aegypti l.the esterases of aedes aegypti were studied in the ovary before and during a gonotrophic cycle and also in fully embryonated eggs by means of disc electrophoresis. during oogenesis no significacant changes can be observed besides a marked increase in the total esterase activity. a different esterase pattern is found in eggs after embryogenesis. the electrophoretic mobility of some esterase bands is highly increased in the ovary compared to other organs. one esterase fraction in the ovary and two ...1975239551
lipase and unspecific esterase activity in the fat body of aedes aegypti l.in the fat body of aedes aegypti a very high unspecific esterase activity and a low lipolytic activity was found. the electrophoretic isozyme patterns of the unspecific esterases show only few changes in the different physiological stages. the activity of the unspecific esterases as well as of the lipase is especially high in young sugar fed and in blood fed mosquitoes which points to special energy requirements in these stages. the role of the unspecific esterases is discussed.19751988
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 ...19761259093
studies with brugia pahangi 12. the activity of levamisole.the effects of levamisole on adults, third stage infective larvae, and microfilariae of brugia pahangi were studied in in vitro culture and in vivo against developing stages in the vector mosquito and in infected cats. in vitro the drug was effective only at dose levels much higher than can be tolerated by mammals. it was active against the developmental stages of the worm in the vector aedes aegypti. the drug was strongly microfilaricidal in cats but less effective against adult worms.19761262689

marylanders defeat philadelphia: yellow fever updated.those strategic points which influence this amateur historian to declare a victory for baltimore and maryland over philadelphia are: i. based upon clinical and epidemiological data, two marylanders, potter and davidge, were among the first to contest rush and his contagion theory; they told him so and published their views. to prove this point, potter went to the extreme of inoculating himself with presumedly infected material. stubbins ffirth, a young university of pennsylvania medical student, ...1976822563
[host range of drosophila melanogaster c virus among diptera and lepidoptera (author's transl)].the host range of the c picornavirus of drosophila melanogaster was studied, using numerous strains of drosophila together with four other genera of diptera and two species of lepidoptera. c virus was injected into the different hosts and serially passaged in them. the extracts from each passage were biologically assayed on virus free d. melanogaster. four different situations were found. 1) a high level of multiplication leading, in 45 strains of drosophilidae, to the early death of the hosts. ...1976823856
[transovarian transmission of a flavivirus, the koutango virus, in aedes aegypti l].the koutango virus dak an d 5443 isolated from rodents of the genus tatera belongs to the genus flavivirus of the faily togaviridae. this virus is very similar to the yellowfever, virus. it is experimentally transmitted from young mouse to young mouse by aedes aegypti. the following observations show on one hand that this virus is found in the eggs of infected a. aegypti and on the other that the females from these eggs transmit the virus to the young mouse by biting them.1976827342
the pathogenesis of vesicular stomatitis virus, serotype indiana, in aedes aegypti mosquitoes. i. intrathoracic injection.analysis of infectious virus particles after intrathoracic injection revealed that aedes aegypti mosquito tissues are capable of supporting the growth of vesicular stomatitis virus (vsv), serotype indiana. although all tissues assayed (salivary gland, midgut, diverticulum, malphigian tubules, and ovary) were capable of supporting vsv growth, the salivary gland was the only organ capable of maintaining an appreciable amount of virus for periods longer than 9 days postinfection. electron microscop ...1976176893
the pathogenesis of vesicular stomatitis virus, serotype indiana, in aedes aegypti mosquitoes, after imbibition of a viremic blood meal.this study showed that vesicular stomatitis virus (indiana) in most instances was not capable of replicating in aedes aegypti when imbibed by the mosquitoes on a viremic host. rapid inactivation of the virus was observed in some cases within 24 hours after imbibition. attempts to demonstrate virus inactivation by midgut contents in vitro were not successful.1976187155
isolation of dengue type 3 from mosquitoes in rangoon.a virus was isolated in suckling mice from aedes aegypti collected from rangoon area, during the month of july 1969. the virus was identified as a member of group b arbovirus dengue type 3, by means of its ability to agglutinate goose erythrocyte at ph 6.6, haemagglutination inhibition and complement fixation tests, and its growth characteristics in aedes albopictus cell cultures. the isolated dengue type 3 virus differs slightly from the indian dengue type 3 virus in its ability to produce haem ...1976140463
hepatitis b surface antigen (australia antigen) in mosquitoes collected in senegal, west africa.during july and august of 1973, 9,198 mosquitoes were collected in the republic of senegal. eight species of mosquitoes were found in the collections: culex thalassius, culex pipiens quinquefasciatus, culex trigripes, culex phillipi, aedes irritans, aedes aegypti, anopheles gambiae, and mansonia sp. specimens were sorted by biological condition; those obviously engorged were designated as (e), females with swollen abdomens not conspicuously blooded were considered gravid (g), and those with norm ...19763983
infective larvae of brugia: escape from mosquitoes into water and subsequent oral infectivity in jirds.published work showed that third-stage larvae (l-3s) escape into water from dead or dying, brugia pahangi-infected, aedes aegypti. the present study revealed the same escape phenomenon among b. pahangi-infected armigeres subalbatus, anopheles quadrimaculatus, and aedes togoi, and among brugia malayi-infected ae. aegypti and ae. togoi. l-3s maintained in water or in lum's solution for 3 hours retained infectivity when tested in orally or subcutaneously exposed jirds; furthermore, l-3s recovered f ...19768999
experimental studies on the transmission of hepatitis b by mosquitoes.culex tarsalis and aedes aegypti mosquitoes were fed on chimpanzees carrying hepatitis b surface antigen (hbs ag) of known infectivity and pools were tested by radioimmunoassay daily for the presence of hbs ag. hbs ag continued to be detected at low levels in mosquito tissue after digestion of the blood meal. inoculation of susceptible chimpanzees with macerated pools of a. aegypti mosquitoes at two intervals after digestion of the blood meal did not produce hepatitis or serologic evidence of he ...19769000

a new sex-linked mutant short wing in aedes aegypti.a spontaneous recessive sex-linked mutant short wing has been discovered in the mosquito aedes aegypti. it is situated less than one cross-over unit from the sex determining locus. in homozygous females, flight is impaired and the survival and fecundity is markedly subnormal. two possible uses of this gene for genetic control operations are envisaged: (a) to provide automatic sexing of males for release and (b) enhancement of the population control potential of other available genetics systems.19761062368
the effect of larval selection on adult resistance to ddt in two strains of the mosquito aedes aegypti (l).evidence is presented which confirms the influence of linkage group ii on adult ddt-resistance in one strain of aedes aegypti (bangkok-mr) but not in another strain (bangkok-hr).19761062367
comparative field cage tests of the population suppressing efficiency of three genetic control systems for aedes aegypti.cycling populations of aedes aegypti were set up in cages and managed in such a way that the populations had a maximum of threefold recovery potential in response to control measures. into three such populations daily releases were made of males which had been chemosterilised, or were double translocation heterozygotes (t1t3) or t1t3 with sex ration distortion (dt1t3). eradication of the populations was achieved with all cases, but the rate of suppression was markedly slower with t1t3 than the o ...197656331

morphometric comparison of the midgut epithelial cells in male and female aedes aegypti l. (insecta, diptera).midgut epithelial cells of male and female aedes aegypti, 3 days after emergence, were compared morphometrically. the results of the present investigation concerning the female, are in good agreement with those of a previous study (hecker et al., 1974), demonstrating that morphometric investigation of midgut epithelia in a. aegypti can successfully be reproduced, and that the mosquito strain used did not show quantitative morphological changes due to laboratory rearing. in males, the cells of th ...1976185746
ultrastructure of the atypic muscles associated with terminalial inversion in male aedes aegypti (l).two sets of opposed, crossed muscles are present in the rotating region of the abdomen in male a. aegypti. these muscles undergo changes during rotation of the genitalia that suggest they function as the driving force for rotation. during this rotation, one muscle of each set contracts and the opposed one becomes elongated. the contracting muscles are atypic physiologically. they contract from 300 mum to about 69 mum, and this requires a period of 18 to 24 hours. they shorten only once and those ...1976974162

comparative activity and properties of lactate dehydrogenase, xanthine dehydrogenase, and dihydrofolate reductase in normal and brugia pagangi-infected aedes aegypti.the amount of xanthine dehydrogenase (xdh), dihydrofolate reductase (dhfr), and lactate dehydrogenase (ldh) in crude extracts of 4- to 5-day-old adult aedes aegypti was determined, and the properties of these enzymes were partially characterized. it was then found that the amount and other selected characteristics of xdh and ldh in extracts of female ae. aegypti processed 5 to 7 days and 12 to 14 days after they had fed upon either normal or brugia pahangi-infected jirds were indistinguishable f ...1977559068
flight muscle ultrastructure of susceptible and refractory mosquitoes parasitized by larval brugia pahangi.on parasitization with larval brugia pahangi the infected flight muscle fibres of "resistant" anopheles labranchiae atroparvus undergo the following ultrastructural changes. the fibres become almost totally devoid of glycogen, their sarcoplasmic reticulum becomes elongate and closely associated with muscle fibrils. these fibrils degenerate and vesicles appear both within the degenerate fibril and within elements of the sarcoplasmic reticulum. vesicles accumulate around the worm and degenerate to ...197714324
influences of blood digestion on the development of plasmodium gallinaceum (brumpt) in the midgut of aedes aegypti (l.).blood digestion of aedes aegypti and development of plasmodium gallinaceum were shifted against each other by giving the mosquitoes two consecutive blood meals. in this way the parasites were exposed to an environment where blood digestion was more advanced than in single blood meals. this procedure had an inhibiting effect on oocyst production when the two blood meals overlapped; an enhancing effect when they were well separated. the results are explained by the action of trypsin-like proteases ...197719955

laboratory studies on the transmission of yellow fever virus by aedes (finlaya) notoscriptus (dipt., culicidae).aedes (finlaya) notoscriptus (skuse), a mosquito which occupies a similar ecological niche to aedes (stegomyia) aegypti (l), the urban vector of yellow fever virus, was screened as a possible vector of this disease. the results indicate that almost certainly ae. notoscriptus is refractory to the virus and could not act as a vector if yellow fever were introduced to australia.197796783
transfer of leprosy bacilli from patients to mouse footpads by aedes aegypti.aedes aegypti mosquitoes which were first allowed to feed on untreated lepromatous leprosy patients, and then to refeed on mouse footpads were found to transfer mycobacterium leprae to the footpads as seen by the subsequent multiplication of the bacilli in the footpads. results presently available are insufficient to come to any conclusion about the actual role of mosquitoes in the transmission of leprosy in the field.1977333183
the influence of the gene sb in culex pipiens on the development of sub-periodic brugia malayi and wuchereria bancrofti.the gene sb (filarial susceptibility, brugia pahangi) in culex pipiens controls the development also of sub-periodic b. malayi, but has no influence on the development of periodic wuchereria bancrofti (ceylon strain). c.p. fatigans (kuala lumpur), c.p. molestus (london) and aedes aegypti (re fm strain) were all susceptible to the ceylon strain of w. bancrofti, with susceptibility rate of 90.3%, 92.9% and 52.6% respectively. however, a low proportion of the larvae in a. aegypti developed to matur ...1977596959
hematophagous insects as vectors for frog trypanosomes.experimental infections of three hematophagous arthropods (rhodnius prolixus, aedes aegypti, and culex pipiens) with a trypanosome of the trypanosoma rotatorium complex found in the frogs hyla crepitans and leptodactylus insularum revealed that a. aegypti is a good host for the flagellate; the course of development in the intestinal tract of the mosquito is described from 15 minutes to 168 hours. c. pipiens showed only low intestinal infections and r. prolixus did not permit development of the p ...1977615322

sterility introduced by release of genetically altered males to a domestic population of aedes aegypti at the kenya coast.the release of males heterozygous for one or two sex-linked translocations was effective in introducing a high level of sterility into a domestic population of aedes aegypti at a rabai village. the effect of the releases continued for several weeks after the release period.1977869107
induction of venezuelan equine encephalitis (mucambo) virus by iododeoxyuridine in chronically infected 'cured' cultured mosquito cells.infection of cultured aedes aegypti mosquito cells with venezuelan equine encephalitis virus (mucambo subtype) results in the establishment of a chronic non-cytopathic infection. infected cells could be 'cured' when they were grown in the presence of immune serum for 3-4 passages. 'cured' cells could then be subcultured repeatedly, in the absence of immune serum, without showing any indication of infectious virus production. when 'cured' cells were exposed to 50 microgram/ml of 5-iodo-2-deoxyuri ...1977873741
on the development of onchocerca volvulus in mosquitoes.in an attmept to find an experimental vector for onchocerca volvulus which can be easily be bred under laboratory conditions, the susceptibility of anopheles gambiae and aedes aegypti to infection with o. volvulus was studied. the mosquitoes were fed on a membrane feeding apparatus containing microfilariae of o. volvulus. whereas a. gambiae was refractory to infection. 14.9% of a. aegypti females became infected with developing stages, 11,2% showed young and mature third-stage larvae as well as ...1977888189
type 1 dengue with hemorrhagic disease in fiji: epidemiologic findings.an explosive epidemic of dengue occurred in fiji between january and july 1975. all laboratory evidence indicated that type 1 dengue was the only prevalent dengue virus. this type had probably not been in fiji for 30 years and over 70% of the population was susceptible. aedes aegypti appeared to be the major vector in urban areas, but circumstantial evidence indicated that aedes rotumae was a vector in at least one remote area. all forms of the clinical spectrum of dengue were seen and reported ...1977889018
cytoplasmic bridges within the follicular epithelium of the ovarioles of two diptera, aedes aegypti and stomoxys calcitrans.the cells of the follicular epithelium of the ovarioles of the mosquito, aedes aegypti (l.), and of the stable fly, stomoxys calcitrans (l.), have been found to be interconnected by cytoplasmic bridges. cytoplasmic bridges have been reported between sibling gamete cells of both male and female insects, but these bridges have not been previously reported to exist between somatic cells of insects.1977894721

an autocidal ovitrap for the control and possible eradication of aedes aegypti.a revolutionary, autocidal ovitrap has been developed as a promising weapon for the control and possible eradication of ae, aegypti, the principal vector of dengue haemorrhagic fever (dhf), in urban high dhf endemic areas. a study carried out with this trap in a highly endemic area for dhf in singapore city, namely the rochor area, has shown this trap to be superior to all other domestic habitats in attractiveness to ovipositing ae. aegypti females.1977887996
autogeny in diverse populations of aedes aegypti from east africa.autogeny in aedes aegypti was found in many diverse populations throughout the range of east africa. degree of autogeny is proposed to be measured either by a relative method using an autogeny index (aix), or by direct count of eggs in dissected ovaries and expressed in percentage. degree of autogeny varied from population to population but it was always higher in the dark feral ae. aegypti formosus than in the domestic ae. aegypti aegypti form. the highest degree of autogeny occurred in the dar ...1977871038
fine structure and role in behavior of sensilla on the terminalia of aedes aegypti (l.) (diptera: culicidae).the terminalia of male and female aedes aegypti (l.) bear numerous hairs of various shapes and lengths, all of which are mechanoreceptors. each hair is innervated by one bipolar neuron which contains ciliary rootlets, two basal bodies, and a region assuming the structure of a non-motile cilium. at the distal tip of the dendrite is a tubular body, a characteristic of cuticular mechanoreceptors. covering the outer dendritic segment is a cuticular sheath which ends proximally in a net-like felt-wor ...1977845972
ultrastructural changes in midgut cells of female aedes aegypti l. (insecta, diptera) after starvation or sugar diet.the ultrastructure of the epithelial cells in the posterior part of the midgut in female aedes aegypti was partly changed after starvation periods of 5 or 8 days. most obvious is a drastic reduction of the amount of rough endoplasmic reticulum (rer), which is responsible for the synthesis of enzymes for blood digestion. a similar influence on rer membranes is to be observed in mosquitoes fed on sucrose solution only, without additional blood meals.1977837408
[studies of the time of effectiveness and the characterization of compounds in insecticide tests with aedes aegypti].the contact-toxicity of 5 insecticides (2 chlorinated hydrocarbons, 2 organophosphate compounds 1 p-substance) are tested against aedes aegypti l (adults). because of the relationship between dosage (quantity of application) and time of effectiveness of a compound, we are able to design a specific curve of time-efficacy of each insecticide at graded intervals (= increasing dilutions). this curve may be characteristic of different pure compounds--possibly in connection with other features. the ti ...197767813

ultrastructural changes in intersegmental cuticle during rotation of the terminal abdominal segments in a mosquito.the terminal abdominal segments of male aedes aegypti rotate 180 degrees within 24 hr after adult emergence, rotation occurring in the intersegmental membrane between abdominal segments vii and viii. the ultrastructure of this rotating membrane is compared with non-rotating intersegmental membranes at different developmental stages. the deposition of cuticle in both the rotating and non-rotating intersegments appears ultrastructurally similar, and follows the sequential pattern described for the ...1977906015
