The AIDS virus is found in the blood just like plasmodia, yellow fever virus,etc. During a blood meal, the mosquito picks up these viruses, plasmodia and other pathogens.However, it is not clear whether these mosquitoes transmit the Aids viruses to the next host unlike the other pathogens.
Dear Agere, This is an interesting question. Please go to the following link. It will useful for you and will give you a clear answer for your question. https://www.ncbi.nlm.nih.gov/m/pubmed/10554479/
Simple the virus in ingested with the blood unlike malaria where part of its life cycle in the mosquito
Mosquitoes are biological vectors, which means that the pathogen (the virus) must replicate in the mosquito tissue before it can be transmitted. Indeed, arboviruses do infect mosquitoes and replicate in the midgut and in the salivary glands, the mosquito is just able to tollerate viral replication, there is no fitness reduction. This is because ZIKV and other arboviruses are thought to be derived from Insect specific viruses, which can only infect mosquitoes. These viruses have evolved to also infect vertebrates, to have more hosts and became arboviruses: Zika, Dengue, West nile... HIV, and the majority of other viruses, have a completely different origin, they were born as vertebrate virus, they infect mammals. So they do not "recognise" mosquito cells and cannot replicate in mosquitoes.

Also mosquitos spp vary in their tolerance to microorganisms replication and devolopment inside them. The vector is discribed as more effecient if it can tolerate microorganism infection and can survive longer time after being infective. Culex pipiens become weaker after being infected with microfilaria which affect and weaken its thoracic muscle and wings inturn so the flight range of infected mosquitos decreases greatly explaining the focality of filariasis

Thanks!
I really like this question, though it was addressed before..
Think about it this way :
What can we learn from this process (no HIV transmission through mosquitoes) to help us fight the transmission of the HIV in the real world?
