Unlike many other mosquito species, which will lay their eggs in any standing water, it was discovered that the Stegomyia females would lay their eggs only in clear water very near to humans.
Gorgas initiated a house-to-house, building-by-building, street-by-street inspection and eradication program that involved fumigation and covering or emptying all water jars, cisterns, rain barrels, buckets, cans--anything that would collect water and provide a place for the Stegomyia to lay their eggs.
Yellow fever was quickly brought under control as the Stegomyia and its breeding places were eradicated.
So, while Gorgas' sanitation teams gathered detailed information on Stegomyia concentrations for their campaign against yellow fever, they also began building a comprehensive database on Anopheles concentrations and habits as well.
18 Stegomyia albopicta mosquitoes were selected in order to be tested for DENV infection.
The occurrence of transovarial transmission of DENV-2 by Stegomyia aegypti in nature was demonstrated from the isolation of dengue virus from naturally infected mosquito larvae showing a minimum infection rate of 1:2,067 for DENV-2 (Sabin, 1952).
Transovarial transmission of DENV by Stegomyia could play an important role in the survival of these viruses in nature.
The sex locus is associated with loci on elements A and B in the three Stegomyia species and Aedes triseriatus, with elements D and F in Aedes atropalpus and with elements C and E in Aedes togoi.
Stegomyia species) the linkage arrangements point to conserved linkages in which both synteny and gene order have been maintained.
That same day, I Kathimerini claimed that efficient measures against Stegomyia mosquitoes should suffice: covering any kind of water container and sewage-connected pipe or container and removing stagnant water from houses, kitchens, washing places, and flower pots.
In addition to confirmation of Stegomyia mosquitoes as the vector and lifelong immunity against DF, the scientists claimed that they also had produced an efficient vaccine; however, it was not to be used commercially.
