microsatellite-based parentage analysis of aedes aegypti (diptera: culicidae) using nonlethal dna sampling.to track aedes aegypti (l.) egg-laying behavior in the field in iquitos, peru, we developed methods for 1) sampling dna from live mosquitoes and 2) high through-put parentage analysis using microsatellite markers. we were able to amplify dna extracted from a single hind leg, but not from the pupal exuvia. removal of a leg from teneral females caused no significant changes in female behavioral or life history traits (e.g., longevity, blood feeding frequency, fecundity, egg hatch rate, gonotrophic ...022308775
daily newspaper view of dengue fever epidemic, athens, greece, 1927-1931.during the late summers of 1927 and 1928, a biphasic dengue epidemic affected the athens, greece, metropolitan area; >90% of the population became sick, and >1,000 persons (1,553 in the entire country) died. this epidemic was the most recent and most serious dengue fever epidemic in europe. review of all articles published by one of the most influential greek daily newspapers (i kathimerini) during the epidemic and the years that followed it did not shed light on the controversy about whether th ...022257469

the harmonic convergence of fathers predicts the mating success of sons in aedes aegypti.during courtship males often communicate information about their fitness to females. the matching of harmonic components of flight tone in male-female pairs of flying mosquitoes, or harmonic convergence, was recently described. this behaviour occurs prior to mating and has been suggested to function in mate selection. we investigated the hypothesis that harmonic convergence is a component of mosquito courtship. a key prediction of this hypothesis is that harmonic convergence should provide infor ...022003255
food availability alters the effects of larval temperature on aedes aegypti growth.variation in temperature and food availability in larval habitats can influence the abundance, body size, and vector competence of the mosquito aedes aegypti. although increased temperature has energetic costs for growing larvae, how food resources influence the developmental response of this mosquito species to thermal conditions is unknown. we explored how rearing temperature and food affect allometric scaling between wing size and epidermal cell size in ae. aegypti. mosquitoes were reared at ...021936315
newer approaches to malaria control.malaria is the third leading cause of death due to infectious diseases affecting around 243 million people, causing 863,000 deaths each year, and is a major public health problem. most of the malarial deaths occur in children below 5 years and is a major contributor of under-five mortality. as a result of environmental and climatic changes, there is a change in vector population and distribution, leading to resurgence of malaria at numerous foci. resistance to antimalarials is a major challenge ...023508211
south-to-north, cross-disciplinary training in global health practice: ten years of lessons learned from an infectious disease field course in jamaica.global commerce, travel, and emerging and resurging infectious diseases have increased awareness of global health threats and opportunities for collaborative and service learning. we review course materials, knowledge archives, data management archives, and student evaluations for the first 10 years of an intensive summer field course in infectious disease epidemiology and surveillance offered in jamaica. we have trained 300 students from 28 countries through collaboration between the university ...021896794
distributions of competing container mosquitoes depend on detritus types, nutrient ratios, and food availability.coexistence of competitors may result if resources are sufficiently abundant to render competition unimportant, or if species differ in resource requirements. detritus type has been shown to affect interspecific competitive outcomes between aedes albopictus (skuse) and aedes aegypti (l.) larvae under controlled conditions. we assessed the relationships among spatial distributions of detritus types, nutrients, and aquatic larvae of these species in nature. we collected mosquitoes, water, and detr ...022707761

direct targets of the d. melanogaster dsxf protein and the evolution of sexual development.uncovering the direct regulatory targets of doublesex (dsx) and fruitless (fru) is crucial for an understanding of how they regulate sexual development, morphogenesis, differentiation and adult functions (including behavior) in drosophila melanogaster. using a modified damid approach, we identified 650 dsx-binding regions in the genome from which we then extracted an optimal palindromic 13 bp dsx-binding sequence. this sequence is functional in vivo, and the base identity at each position is imp ...021652649
behavioral observations and sound recordings of free-flight mating swarms of ae. aegypti (diptera: culicidae) in thailand.sound plays an important role in the mating behavior of mosquitoes, including aedes aegypti (l). males orient to the fundamental wing beat frequency of females, and both sexes actively modulate their flight tone before mating to converge at harmonic frequencies. the majority of studies on mosquito mating acoustics have been conducted in the laboratory using tethered individuals. in this study, we present the first free-flight recording of naturally forming ae. aegypti swarms in thailand. we desc ...021845959
interlocked feedforward loops control cell-type-specific rhodopsin expression in the drosophila eye.how complex networks of activators and repressors lead to exquisitely specific cell-type determination during development is poorly understood. in the drosophila eye, expression patterns of rhodopsins define at least eight functionally distinct though related subtypes of photoreceptors. here, we describe a role for the transcription factor gene defective proventriculus (dve) as a critical node in the network regulating rhodopsin expression. dve is a shared component of two opposing, interlocked ...021663797
tagetes erecta linn. and its mosquitocidal potency against culex quinquefasciatus.to investigate mosquitocidal effects of ethanolic extract of flowers of tagetes erecta (t. erecta) and its chloroform and petroleum ether soluble fractions against the larvae of culex quinquefasciatus (cx. quinquefasciatus).023569756
toxicological effects of sphaeranthus indicus linn. (asteraceae) leaf essential oil against human disease vectors, culex quinquefasciatus say and aedes aegypti linn., and impacts on a beneficial mosquito predator.use of environmentally friendly, decomposable natural products for effective vector control has gained considerable momentum in modern society. in this study, essential oil of sphaeranthus indicus (si-eo) was extracted and further phytochemical screening revealed fourteen compounds with prominent peak area percentage of 24.9 and 22.54% in 3,5-di-tert-butyl-4-hydroxybenzaldehyde and benzene,2-(1,1-dimethylethyl)-1,4-dimethoxy, respectively. the si-eo was further evaluated for their larvicidal res ...028455566

the incubation period of yellow fever in the mosquito.1. the yellow fever virus was found in infectious form in aedes aegypti throughout the entire period of the extrinsic incubation, as demonstrated by the injection of the bodies of mosquitoes into normal rhesus monkeys at daily intervals after the insects had fed on an infected animal. 2. the virus was transmitted through the bite of the mosquitoes, in one experiment on and after the 9th day, and in two experiments on the 12th day after the initial infecting feed. 3. the pathologic changes produc ...192819869467
studies on yellow fever in south america : iv. transmission experiments with aedes aegypti.1. batches of aëdes (stegomyia) aegypti which had fed on monkeys in the early febrile stage of yellow fever and which has subsequently passed the usually accepted extrinsic incubation period for the virus, failed to transmit the disease to normal monkeys in approximately fifty per cent of the experiments. during the same time over eighty per cent of blood transfers were successful. 2. the monkeys which failed to show fever following mosquito bites later proved resistant to the inoculation of blo ...192919869665
possibility of hereditary transmission of yellow fever virus by aedes aegypti (linn.).attempts to obtain passage of yellow fever virus from one generation to the next in a. aegypti were unsuccessful. subcutaneous injections at varying intervals of a saline emulsion of 200 eggs laid by an infective lot of mosquitoes produced no reaction in six normal m. rhesus monkeys. negative results were also obtained in five biting and two injection experiments with progeny of the same infective lot of mosquitoes in which seven normal monkeys were used. the eggs consisted of batches laid after ...192919869656
the filtrability of yellow fever virus as existing in the mosquito.the virus of yellow fever as it exists in aëdes aegypti mosquitoes, both in their so-called infective stage and in the intermediate condition termed the "incubation period", is capable of passing through berkefeld n filters when suspended in normal monkey serum, although earlier investigators have shown that the virus from infective mosquitoes will not do so when suspended in physiological salt solution. the virus of yellow fever as it exists in mosquitoes behaves with regard to filtration throu ...192919869658
recent laboratory contributions to the control of yellow fever: (section of tropical diseases and parasitology).the most important recent laboratory contributions to the control of yellow fever will be briefly summarized under three headings: (1) methods of diagnosis, (2) transmission, and (3) protection.(1) methods of diagnosis.-the development of improved methods of identification, in particular by immunity tests, has made it possible to diagnose yellow fever with much greater certainty. moreover, since the immunity following an attack of the disease is usually of life-long duration, it is possible to d ...193319989606
the transmission of equine encephalomyelitis virus by aedes aegypti.in confirming kelser's work on the transmission of equine encephalomyelitis of the western type by aëdes aegypti it has been learned that the mosquitoes must be fed virus of high titer if positive results are to be secured. a period of from 4 to 5 days after feeding either on infected guinea pigs or on brain containing virus must elapse before the disease is transmitted by biting, but after this time transmission regularly results for a period of about 2 months. by inoculation, virus can be demo ...193519870442
