primary lymph node responses to mosquito bites.	post-auricular lymph node responses and changes in fresh weight of thymus and spleen of hamsters and mice at 4 and 8 days after primary exposure of both ears to 20 bites by the mosquito aedes aegypti were studied quantitatively. in both hosts lymph node changes characteristic of the development of cell-mediated immune responses and those which are believed to lead to antibody production occurred, with the emphasis on the latter phenomena. no reactions of thymus and spleen were observed. the resp ...	1977	848080
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.	1977	887996
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 ...	1977	871038
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 ...	1977	845972
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.	1977	837408
[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 ...	1977	67813

[results of a survey of potential dengue vectors in the neo-caledonian archipelago].	the author gives the results of an entomological survey in neo-caledonian archipelago (new caledonia and loyalty islands), november-december 1972. concerning the distribution and the abundance of aedes aegypti, the local dengue vector, this study shows the presence of this culicid not only in noumea, but also all along the western developped coast of new caledonia, and in ouvea island. this constitutes a great risk of outbreak extension from noumea if a dengue virus is again imported there.	1976	1036473
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, ...	1976	822563
[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. ...	1976	823856
[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.	1976	827342
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
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.	1976	1262689

isolation of chikungunya virus contaminating an aedes albopictus cell line.	an aedes albopictus cell line was found contaminated with structures morphologically compatible with an alphavirus. rapid isolation of a cytopathic virus was effected by combining sonication, concentration with aquacide ii-r, rate zonal sedimentation and subsequent plating of fractions on vero cells under agar overlay. the virus caused neithedeath nor disease on inoculation into infant and adult mice. it produced a c.p.e. in vero and bhk 21 cells, and multiplied in singh's aedes aegypti cells. t ...	1975	806659
adaptation studies with ross river virus: retention of field level virulence.	two field strains of ross river virus (rrv) which differed in virulence for laboratory mice were maintained without detectable change in virulence when passaged alternately in aedes aegypti mosquitoes and newborn mice. no biological mechanism or selection pressure was identified to explain this suppression of the usual change to higher virulence observed when rrv is passed serially in infant mice. the maintenance of initial virulence by alternating passages appears to be related to the fact that ...	1975	808589
multiplication of venezuelan equine encephalitis (mucambo) virus in cultured mosquito cells.	venezuelan equine encephalitis (mucambo) virus was able to multiply at 28degree c in cultured mosquito cells (aedes aegypti and aedes albopictus) without inducing any apparent cytopathology. the kinetics of virus multiplication was similar in mosquito and mammalian (vero) cells. twelve to twenty four hours post-infection, a maximum of 10-50 per cent of the cells were engaged in virus production; however, almost immediately this proportion fell abruptly tending to stabilize in the order of 0.01 t ...	1975	813617
[the mechanism controlling the crossing of the vector's stomach wall by microfilariae (dipetalonema dessetae-aedes aegypti)].	in some of the human filariasis, the number of microfiliariae which succeed in crossing the vector's stomach wall is smaller when the number of ingested microfilariae is larger (limitation). in the couple dipetalonema dessetae-aedes aegypti, this phenomenon appears to be due to a specific lysis of the stomach cells invaded by the microfilariae. this reaction is started when the microfilariae are very numberous. there is "information" transmitted to the whole of the vector's stomach.	1975	813899

linkage of the genes for ddt and dieldrin resistance in larvae of the mosquito aedes aegypti.	the ddt resistance gene rddt1, and the dieldrin resistance gene rd1 have been mapped on linkage group ii with respect to visible markers, in the mosquito aedes argypti l. the best interpretation of the data gives the order wa - rdl - ds rddt1 - s - y but was - rdl -ds - y - s - rddt1 is also possible. h is very loosely linked with rddt1. the length of the linkage group has been considerably extended from previous studies.	1975	1203767
internal regulation of rate of digestion of blood meals in the mosquito, aedes aegypti.		1975	1185004
suppression of pupal esterase activity in aedes aegypti (diptera: culicidae) by an insect growth regulator.	changes in non-specific esterases of aedes aegypti were noted during pupal development. one esterase band was found to increase markedly within 3 h of pupation and this increase in activity was suppressed by prior treatment of larvae with an insect growth regulator, zr 515. it is suggested that the esterase activity may help to reduce endogenous levels of juvenile hormone during metamorphosis and that the growth regulator may prevent this normal regulation.	1975	1204757
