- Can't wait until the IDSA declares a mosquito be required to be attached for 36-48 hours in order to transmit disease.
For those new to lyme, the reference here is the ridiculous myth the IDSA / CDC insist upon for ticks to transmit lyme. Not true. The instant the tick parts break skin, the blood supply is exposed.
(It would be very rare to be bitten by a born-with-lyme nymph tick that has never had a blood meal before. Still, even in such a tick, spirochetes are not just going to stay locked away in their stomach for days on end once they started eating anything). -

Since the tick injects tick spit to glue the tick in place, anesthetize the area and to thin the blood, it might inject spirochetes immediately.
Also tick bite includes sucking blood in and out and then at the end of its meal, injecting all the contents of its gut including all the disease organisms it carries in order to dissolve the glue, so there is lots of opportunity to infect.
With mosquitoes, it would have to be proven that the mosquito could while sucking blood, inject the contents of its innards.
I guess the next step is to see if the infected mosquito could infect a host - probably a mouse.

Borrelia-infected mosquitoes infecting rodents was demonstrated back in the 80's. Sorry, cannot recall the study, only that I read it.
That particular avenue of inquiry seemed to hit a wall, though, after that. I don't think much looking was done. Everything kinda fell off the edge of the world in the early 90's, research wise.

[neutral tone of voice here, I realize after posting this, it could sound snippy. Not intended. I just don't have words / brain / energy to make the tone just right.]
Well, mosquitoes have been spreading all other kinds of disease / infections, so it's already proven their bite can directly spread infection.
It may not be just about what all is in their gut but also on their mouthparts, on their body.
Even a needle stick from a "dirty needle" can spread various kinds of infections in human.
Whatever infection is on their "mouth" or in the blood of their meal host (or whatever kinds of infections are in the water they drink, where they land (sewers, etc.) can be spread to its next, and subsequent, meal hosts. -

- Wow, if this does not have us all make sure we don't have any standing water / breeding pools for mosquitoes, not sure what will.
This is far more expansive than I had thought. Still, their inclusion list is not an exclusion list, likely the list is far beyond this.
I'm also thinking that they may find previous thinking about how just one kind of mosquito spreads this or that, well, even now with Zika virus, they are finding it in other kinds than in the one they thought it was limited to.
malaria, dengue, filariasis, West Nile virus, chikungunya, yellow fever, Japanese encephalitis, Saint Louis encephalitis, Western equine encephalitis, Eastern equine encephalitis, Venezuelan equine encephalitis, La Crosse encephalitis[1] and Zika fever.
Nearly 700 million people get a mosquito borne illness each year resulting in greater than one million deaths. . .
Types
Protozoa
The female mosquito of the genus carries . . . .
Myiasis
The human botfly (Dermatobia hominis) attacks and uses a mosquito during mid-flight to deliver its eggs and transfer it to a person; the eggs are in the underside of the mosquito vector which is stuck with a special glue.
When the mosquito takes a blood meal from its human host, the body heat of the mammalian host melts the glue and the eggs hatch into larvae which feed on human flesh and blood. Other botfly use the same strategy as the human botfly.
Helminthiasis
Some species of mosquito can carry the filariasis worm, a parasite that causes a disfiguring condition (often referred to as elephantiasis) characterized by a great swelling of several parts of the body; worldwide, around 40 million people are living with a filariasis disability.
Virus
The viral diseases yellow fever, dengue fever, Zika fever and chikungunya are transmitted mostly by Aedes aegypti mosquitoes.
Other viral diseases like epidemic polyarthritis, Rift Valley fever, Ross River fever, St. Louis encephalitis, West Nile virus (WNV), Japanese encephalitis, La Crosse encephalitis and several other encephalitic diseases are carried by several different mosquitoes.
Eastern equine encephalitis (EEE) and Western equine encephalitis (WEE) occurs in the United States where it causes disease in humans, horses, and some bird species. . . .
. . . Species
Some viruses tend to be specific to a species and/or genus of mosquito. The following mosquito species transmit disease to humans/animals: [See CHART] -

- A hint for relaxing on the deck / patio:
get a fan that is safe in case of rain - or "shoot it through a patio door" - a light breeze can make it impossible for mosquitoes to fly into to. A light breeze from a fan will also make all your selfies appear as if you are on a cruise, wind in your hair . . . . Ahhh. -

- Another consideration on borrelia transmission: [my speculation, here, solely] the cystic form may be transferred and no one ever looks for that in the tests they do. Most researchers don't even consider that borrelia can morph (or more precisely?) change forms back and forth. And there are several forms, not just spirochete and cystic / round body. -
