It is to note that Aedes aegypti had been present on Oahu and Kauai prior 
to the de/r/*e outbreak in 1943-44 which led to the execution of strict control 
measures which , in turn, resulted in the eradication of this species from these 
two islands. Also, a survey in 1949, conducted on Oahu, failed to show the 
presence of this species. On Kauai, the last recorded observation of aegypti 
was in 1945; a survey made in 1957, by Dr. A.D. Hess , U.S.P.H.S., Entomolo¬ 
gist, showed no signs of this species being present. Also, Aedes aegypti was 
present on Maui up until 1966. However, this species has not been recovered 
from that island since April 1966. 
2. Medical implications 
It must be realized that it is entirely possible for other species of 
mosquitoes to be accidentally introduced into the "Paradise of the Pacific"• 
That is, according to U.S. Public Health Service records in Hawaii, well over 
3 
100 species of mosquitoes have been recovered from aircraft arriving in Hawaii 
over the years. One of these being Culex tritacniorhynchus . the primary vector 
of Japanese "B" Encephalitis. While most (but not all) of these specimens have 
been dead at the time of recovery, it has been amply demonstrated that mosqui¬ 
toes can be transported alive by aircraft for long distances at high altitudes 
(Sullivan, et. al., 1961). 
Oulex quinquefasciatus Say has been shown to be a natural or experimantal 
vector of the following diseases: Filariasis, encephalitis, avian malaria, and 
fowl pox. Aedes aegypti (Linneaus) has been shown to be a natural or experimental 
vector of the following diseases: Yellow fever, dengue, filariasis, and 
encephalitis. This species has also been shown to be a vector of Dirofilaria 
iriTTiitis (Leidy) which causes heartworm in dogs. Aedes ( Stegomyia ) albopictus 
(Skuse) has been shown to be a natural or experimantal vector of the following 
diseases: Dengue, yellow fever, and encephalitis.
