Do mosquitoes carry human DNA?

Human DNA was prepared from mosquitoes (Culicidae) which were collected in a room shared by four human individuals. Several insects did not contain human blood and DNA preparation from them was not successful. However, high molecular weight human genomic DNA could be isolated from four insects.

Do mosquitoes inject DNA?

The process starts with the mosquito eggs, which are 1 mm long tubes (. 039 of an inch long). Scientists inject a miniscule amount of new DNA containing the lethal gene, about 10 thousand-millionths of a litre, into the mosquito eggs using a special glass needle.
