| susceptibility of selected strains of aedes aegypti and aedes albopictus (diptera: culicidae) to chikungunya virus. | the relative susceptibility of selected strains of aedes aegypti (l.) and aedes albopictus (skuse) fed on a viremic monkey to infection with chikungunya virus was determined. infection rates were consistently higher in 10 strains of ae. albopictus tested than in 7 strains of ae. aegypti tested, regardless of the geographic location from which the strains originated or the dose of virus ingested. similarly, virus dissemination rates were higher in the ae. albopictus strains compared with the ae. ... | 1992 | 1313111 |
| influence of short time exposure to an insect growth regulator, hexaflumuron, on mortality and adult emergence of vector mosquitoes. | hexaflumuron, an insect growth regulator (igr), was found to greatly affect the development of immatures and emergence of adults of three species of vector mosquitoes, culex quinquefasciatus, aedes aegypti and anopheles stephensi, when larvae were subjected to short time exposure of < or = 1 h. this igr could completely prevent adult emergence even at a minimum exposure time of 10 min at 0.001, 0.01 and 0.1 mg/l. on treatment, larval and pupal mortality as well as varying degrees of morphogeneti ... | 2007 | 1308571 |
| [observation on the effectiveness of repellent coating against mosquitoes]. | the present paper reports on the effectiveness of a repellent coating for the first time. the repellent coating was made by combining deta (n,n-diethyl-meta-toluamide) with slow-releasing reagent. with this coating employed in the laboratory against aedes aegypti, the rate of blood-sucking was 3.9-9.5% and the rate of protection was 88.9-95.3% for 1-720 days. during 1-77 days' field trial, the rpi (relative population index) was 0-8.98% in the day-time and 0.74-17.15 during the night-time agains ... | 1992 | 1307278 |
| importance of ecology in aedes aegypti control. | aedes aegypti is one of the world's most widely distributed mosquitos and is of considerable medical importance as a vector of dengue and yellow fever. not surprisingly therefore there has been more written on its biology than any other mosquito. the present paper summarizes ecological studies undertaken on this vector, including those on pre-adult mortalities, life-tables, adult dispersal and survival rates. in discussing surveillance techniques it is pointed out there are still no reliable met ... | 1992 | 1298074 |

| the diel pattern of entry to outdoor oviposition sites by female aedes aegypti (l.) (diptera: culicidae) that then laid eggs there: a preliminary study. | experimental observations, made outdoors during the dry and wet seasons in trinidad, demonstrate that more than 70% of female aedes aegypti that are destined to oviposit within the next two hours enter ovitraps during the first and last two-hour periods in the day, a finding consistent with the diel pattern of oviposition recorded earlier at the same site. it is possible that proportionately more eggs are laid in the morning peak during the dry season than the wet season. fewer eggs are laid wit ... | 1992 | 1288434 |

| 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 |
| 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 |
| changes in volume of the rhabdom in the compound eye of aedes aegypti l. | the volume of the rhabdom in compound eyes of mosquitoes decreases upon illumination. this decrease is probably mediated by a bleaching of the visual pigment, since blue light is most effective in producing the change and red light is least effective. the reduction in rhabdom volume appears to be a result of rhabdomal membrane loss to coated vesicles and multivesicular bodies. these organelles were seen most frequently in blue adapted eyes, markedly less frequently in red adapted eyes, and only ... | 1976 | 1255121 |

| results of spraying with ultra-low-volume malathion at ground level in panama city. | several ultra-low-volume (ulv) sprayings of technical malathion (95 per cent) were carried out in panama city. their purpose was to find out how useful this ulv technique could be in helping to combat mosquitoes, especially aedes aegypti. two residential areas were selected as sites for the trials. one of these was san francisco, a district near the shoreline of the bay of panama with many individual houses and a few tall buildings. the other was el cangrejo, a district further inland containing ... | 1975 | 1212538 |
| 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 |
| 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 |
| linkage of a gene for ddt-resistance in adults of the mosquito aedes aegypti. | the gene rddt2, which gives resistance to ddt in the imago of aedes aegypti l. has been mapped on linkage group iii with respect to six visible markers. the best interpretation of the order of the genes is:- blp - blt - co - fz - wi -rddt2 - min, but the order blp - blt - co - fz -rddt2 - wi - min is also possible. | 1975 | 1203761 |

| 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 ... | 1977 | 889018 |
| 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 ... | 1977 | 888189 |
| 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 |

| 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 ... | 1977 | 873741 |
| 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 |
| 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. | 1977 | 869107 |
| effect of polyene macrolide antibiotics on invertebrate tissue culture cells. | the effect of amphotericin b (ab) and amphotericin b methyl ester (ame) on viability and dna synthesis in three insect cell lines, trichoplusia ni (tn) carpocapsa pomonella 169 (cp) and aedes aegypti (aa), has been evaluated. in all cases ame was less toxic than ab and inhibited dna synthesis to a lesser degree than ab. however, the three cell lines differed in their response to the two polyene macrolide antibiotic preparations. tn and aa cell responded in a similar manner when exposed to either ... | 1977 | 863791 |
