(diptera: culicidae) on the kenya coast. ii. food as a main regulatory factor.	experiments were carried out in a village on the kenya coast to investigate observed differences in pupal productivity of aedes aegypti breeding in indoor pots. daily addition of maize gruel, the staple food of villagers, to pots of high and low mosquito production promoted an increase of pupal numbers, although daily introduction of first-instar larvae did not significantly affect pupal production. differences in pupal productivity were not related to differences in the numbers of eggs laid in ...	1984	6547039
development of dirofilaria repens in aedes aegypti reared in contrasting habitat.	the susceptibility of dirofilaria repens infection in aedes aegypti adults reared in hay-infusion and tap-water during their larval stages was tested. ae. aegypti reared in hay-infusion ingested a bigger amount of blood than those reared in tap-water but harboured fewer d. repens larvae (developing and arrested). the difference in the susceptibility of mosquitoes from the two treatments was correlated with the difference in the robustness of the mosquitoes.	1983	6612416

transovarial transmission of dengue viruses by mosquitoes: aedes albopictus and aedes aegypti.	transovarial transmission of all four dengue serotypes was demonstrated in aedes albopictus mosquitoes. the rates of such transmission varied with the serotype and strain of virus. in general, the highest rates were observed with strains of dengue type 1 and the lowest with dengue type 3. surprisingly, despite the use of viral strains of the four dengue serotypes which gave the highest rates with ae. albopictus, transovarial transmission was observed in aedes aegypti only with dengue type 1, and ...	1983	6625066
toxicity of bacillus thuringiensis subsp. israelensis to adult aedes aegypti mosquitoes.	adult female aedes aegypti mosquitoes were killed by the parasporal crystals of bacillus thuringiensis subsp. israelensis (onr-60a) when the crystals were introduced into the insect midgut as an enema. the 50% lethal dose for intact parasporal crystals was 0.21 microgram/mg of mosquito (wet weight), and for solubilized crystals the 50% lethal dose was 0.04 microgram/mg. these values were compared with 50% lethal concentrations in a free-feeding larval mosquito bioassay of 0.018 and 1.28 microgra ...	1983	6625566

[action of the delta-endotoxin of bacillus thuringiensis var. israelensis on cultured cells from aedes aegypti l].	the effects of bacillus thuringiensis var. israelensis delta-endotoxin were investigated on a cell culture of aedes aegypti with the electron microscope. the ultrastructural changes following intoxication were: disintegration of endoplasmic reticula by the formation of spherical structures; condensation and then swelling of mitochondria with disappearance of internal cristae; frequent dilatation of the perinuclear space; cellular lysis. the action of a metabolic inhibitor, 2,6-dibromophenol (2,6 ...	1983	6638755
vertebrate host specificity and experimental vectors of plasmodium (novyella) kempi sp. n. from the eastern wild turkey in iowa.	vertebrate host specificity, experimental laboratory vectors, and a description of plasmodium (novyella) kempi sp. n. from eastern wild turkeys (meleagris gallopavo silvestris vieillot) in iowa are presented. plasmodium kempi is infective for domestic turkeys, bobwhites (colinus virginianus), chukars (alectoris graeca), guinea fowl (numida meleagris), peacocks (pavo cristatus), and canaries (serinus canaria), produces a transient infection in mallards (anas platyrhynchos) and domestic geese (ans ...	1983	6644918
transmission of dengue virus by orally infected aedes triseriatus.	transmission of dengue type 1 was demonstrated for 3 strains of aedes triseriatus mosquitoes after oral infection. rates of infection were similar to those observed in a control strain of aedes aegypti. three additional species belonging to the subgenus protomacleaya (aedes brelandi, aedes hendersoni, and aedes zoosophus) were also susceptible to oral infection with dengue type 1 virus but transmission could not be demonstrated although virus was detected in the salivary glands of infected mosqu ...	1983	6650743

linkage relationships of eleven enzyme loci in the aedes scutellaris group.	linkage relationships of 11 enzyme loci were determined in backcrosses between aedes polynesiensis and aedes kesseli. three linkage groups established were aat2-lap2-me-sex, cat-ao-pgm-idh2-est6, and gpi-odh-pgd. lap2 and cat have not been previously mapped in aedes. locus order and linkage groups were the same as those observed for seven loci mapped in aedes aegypti. the significance of the observed similarities in chromosome organization and differences in crossover values among closely relate ...	1983	6670992
susceptibility of aedes aegypti to infections with dirofilaria immitis and dirofilaria repens.	eight stocks of aedes aegypti-4 geographic stocks and 4 selected stocks-were tested for their susceptibility to infection with dirofilaria immitis and d. repens. four of the stocks were found to be susceptible and the other 4 were refractory of infection with d. immitis. all the stocks of ae. aegypti that were susceptible to d. immitis were also susceptible to d. repens but the stocks that were refractory to d. immitis were all partially susceptible to d. repens.	1983	6673132
insecticidal effect of aliphatic alcohols against aquatic stages of aedes mosquitoes.	effectiveness of certain long carbon chain aliphatic alcohols as ovicides and larvicides was investigated under laboratory conditions against eggs and larvae of aedes aegypti and aedes scutellaris. out of the eight alcohols tested, three (1-decanol, 1-undecanol and 1-dodecanol) proved to be very effective. the hatching of mosquito eggs was inhibited at a dosage of 5 to 7 litres/hectare. first, third and fourth instar larvae were killed at a dosage of 3 to 7 litres/hectare. first instar larvae we ...	1983	6683011
characterization of antigens on mosquito midgut stages of plasmodium gallinaceum. i. zygote surface antigens.	we have defined the surface protein antigens on plasmodium gallinaceum zygotes using radioiodination methods and rabbit anti-zygote serum which blocks transmission of the parasite to aedes aegypti mosquitoes. fifteen protein bands (1-15) in the molecular weight range of 40 000-240 000 and one band at the bromophenol blue dye marker were labelled by the lactoperoxidase and iodogen (1,3,4,6-tetrachloro-3 alpha,6 alpha-diphenylglycoluril) methods. the localization of these radioiodinated components ...	1983	6683783
increased intradermal probing time in sporozoite-infected mosquitoes.	because malaria sporozoites destroy segments of the salivary glands of vector mosquitoes, we determined whether salivary function is impaired. such pathology would result in a prolonged intradermal probing phase of feeding behavior, because the role of saliva is to help locate blood vessels. indeed, non-infected aedes aegypti mosquitoes probed for a shorter period than did either sporozoite-infected or saliva-deprived mosquitoes. salivary apyrase activity is reduced to a third following maturati ...	1984	6696175
