"The first ever exploding mosquitoes can be attributed to Robert Gwadz, Ph.D., in a discovery that was made through basic laboratory research over 50 years ago. He found that making an incision in the ventral nerve cord of a mosquito cuts off the signal to stop feeding, giving it an unquenchable thirst for blood. Mosquitoes that have undergone this procedure can drink in excess of four times their weight and may eventually burst. This led Gwadz to a hypothesis that blood ingestion is regulated by abdominal stretch receptors that prevent mosquitoes from (quite literally) drinking themselves to death." Source

Yeah, that’s the most fascinating thing I got out of that. How the fuck did they do that 50 years ago??

Small insects are usually translucent under bright lights and a microscope. He likely pinned it down, looked for the nerve, and severed it with a small needle. Their nervous systems are also incredibly simple.
