Adult specimens of the genus
Aedes mosquitoes are responsible for the
transmission of viral diseases such as
zika and dengue. Scientists have
produced a modified form of the
male Aedes mosquitoes. The
descendants of these male mosquitoes
they die before reaching adulthood. East
method of reducing the spread of a
disease depends on
(1) vaccines that stimulate the system
immune from infected people
(2) administer medications that reduce
symptoms of the disease
I
(3) the use of natural selection in order
to modify viruses so that they are no longer
pathogenic
(4) the use of genetic engineering to
reduce mosquito population
