Male fruit flies enjoy ejaculation

A probe of the brain’s reward system looks at Drosophila sex (or lack thereof) and drinking.

Moody red lighting in a lab is helping researchers figure out what fruit flies like best about sex.

The question has arisen as scientists try to tease out the neurobiological steps in how the brain’s natural reward system can get hijacked in alcoholism, says neuroscientist Galit Shohat-Ophir of Bar-Ilan University in Ramat Gan, Israel.

Male fruit flies (Drosophila melanogaster) were genetically engineered to ejaculate when exposed to a red light.

Ejaculation increased signs in the insects’ brains of a rewarding experience and decreased the lure of alcohol, researchers found.

After several days in this red-light district, the flies tended to prefer a plain sugary beverage over one spiked with ethanol.

Males not exposed to the red light went for the boozier drink, Shohat-Ophir and colleagues report April 19 in Current Biology.

He does seem to have that familiar ‘silly grin’ on his face, doesn’t he.

“In female rats, copulation needs the right circumstances to evoke reward chemistry.”

I wonder if that would work as a pick-up line....”hey, how about a little reward chemistry”?

Oh man, you never should have started this thread.

By the way, I am really happy for the male fruit fly.

Good reason to keep my swatter handy.

Someone’s were.

What kind of mind would think up a research project like this?

What kind of mind would agree to fund it?

Maybe it’s better not to know.

Ash borers are decimating trees in the northeast and I hear now that the ashes are going they are targeting other hardwoods, and these *researchers* have nothing better to do than try to figure out the obvious?

The government should provide free condoms for fruitflies. Getting them to use them might be a problem, though.

You don’t have to be a fly to enjoy that.

I think all critters that do “it”, share this trait.

Tell that to a drone honey bee.

I don’t think it’s known with 100% certainty whether fruitflies suffer from E.D. This is definitely something that needs looking into.

Yes, but this study focused specically on the 'male fruit' variety

Nothing new was learned in this study...

For females, regardless of species, it’s all about “feelings”.

For guys? Not so much.

All fruit flies look pretty much the same to me, LOL, so hard to tell.

I read a story once long ago where they irradiated some fruit flies to make them sterile. Then they were going to release them in order to reduce the fruit fly population. All this cost a lot of money.

Unfortunately, they released the flies next to a house that had been freshly painted. The flies all went over to the house and got stuck on it.
