4. Mosquito breeding areas in Hawaii"^ 
Culex auinquefa3ciatus prefers to breed in ground pools and sluggish 
streams, particularly if the water is foul. This mosquito will also breed in 
artificial containers and is usually to be found near human habitations. The 
eggs of Culex auinquefasciatus cannot withstand drying. 
Aedes aegypti are highly domestic mosquitoes which prefer artificial con¬ 
tainers to breed in, such as bottles, tin cans, vine bowls, tire castings, 
cisterns, etc. They have also reportedly been found in natural containers such 
as tree holes, rock holes, and sometimes in plants that nold water. They ars 
rarely found in dirt-line pools. The eggs of Aedes aegypti. are resistent to 
drying; often for many months. 
Aedes alboDictus breeds in artificial and natural containers, ihis

mosquito has a greater tolerance for colder weather than does Acae_s aegypti; 
consequently the species is found in lower forest areas of the mountains as 
well as in urban areas. The larvae are found wore often in natural water 
containers such as spider and pineapple lilies, ape plants, tree holes, roex 
holes, etc. The eggs of Aedes albopictus are reisitent to drying for a period 
of many months. 
«• 
Aedes vexans nocturaus differs from the other three species of noxious 
mosquitoes found on the Hawaiian Islands in that it is a floodwater mosquito 
which does not normally breed in artificial containers close to human habitation* 
It prefers flat, semi-marshy, pitted or neglected agricultural land subject to 
periodic flooding. It is normally a temporary ground pool breeder. The eggs of 
Aedes vexans can withstand dessication and may remain viable for a year or mOxO, 
and hatch when flooding occurs. 
5. Biological Control 
The subfamily Toxorhynchitinae, commonly known as cannibal mosquitoes, 
consists of a large mosquito which occurs in tropical as well as temperate climate.
