Only certain species of mosquitoes of the Anopheles genus—and only females of those species—can transmit malaria.
Malaria is caused by a one-celled parasite called a Plasmodium. Female Anopheles mosquitoes pick up the parasite from infected people when they bite to obtain blood needed to nurture their eggs. Inside the mosquito the parasites develop and reproduce. When the mosquito bites again, the parasites mix with its saliva and pass into the blood of the person being bitten.
Both Male and female anopheles mosquito feeds on various sources of sugar such as nectar. In addition to the sugar source female anopheles mosquitoes require iron and other nutrients for the developments of their eggs. Therefore she bites the mammals to obtain the blood. Usually, people get malaria by being bitten by an infective female Anopheles mosquito. Only female anopheles mosquitoes can transmit malaria and they must have been infected through a previous blood meal taken on an infected person.
The female anopheles mosquito transfer malaria in order to obtain proteins from the human blood plasma, which they use in their eggs. The male does not need these proteins hence they do not transfer malaria.
Only female mosquitos take a blood meal, as they need to to produce eggs. With no males feeding, there is no chance to spread malaria.
Female mosquitoes are the only ones that need to gorge on blood in order to lay eggs.
in newly research studies it has found that like human beings contain a bacteria in intestine which is helpfull to us which is also known as PROBIOTIC BACTERIA. in the same way male anopheles mosquito contains a bacteria which is having capability to kill the pathogen where as it was absent in female anopheles mosquito. so it cause diasease but not by male mosquito. thanks for answering my question
Two important events in the life of female mosquitoes are egg development and blood digestion. After taking a blood meal, the midgut of the female synthesizes proteolytic enzymes that hydrolyze the blood proteins into free amino acids. These are used as building blocks for the synthesis of egg yolk proteins." So only females spread malaria since they're the only ones who need to feed on our blood and spread the parasite during feeding...
