Aggression in Drosophila (fruit flies)

[CountOfSaintGermain]

what I find quite interesting is that in this territory they are fighting while at the same time, in neighbouring territories they prefer to live "harmoniously"

[emkesslerkc]

Could you describe the setup for those that may appreciate replicating this. Mutant strain if any? Food? Etc...

[HuMoDz]

fruit fly used TACKLE

nothing happens

fruit fly used KICK

nothing happens

fruit fly used GRAB

nothing happens

how could they harm each other that way?

[yankale]

WOW in 3:30 KARATE KICK hahaha,nice video .interesting.

[Druhue]

inject a fruit fly with phenylalanine..and video that

[MuGeNTOM]

UFC!

ultimate fly championship

[patriciasma]

Who won???  You should take bets. Give one a line of cocaine right before

[theraveniscool]

"its mine"

"no its mine!!"

seriously cant they learn to share :\

LOL

[xissburg]

awesome wrestling there. I dont think they can hurt each other.

[ChinatownNoodles]

Been working with Drosophila for a year now... never knew they could get aggressive!

[HempForPresident]

Kick his ass, seabass!

pwned

[smerrigan]

thank god for van der waals forces

[pose716]

the last three comments, read from down to up please

[pose716]

I have observed for 30 minutes but all they want to do is find a way out of the chamber. i know theres also the factor of age where 3-7 day old flies only fight, but can u help to elicit aggressiveness in these flies? i need to be able to quick because i need to take trials soon. thank you.

[pose716]

i put 8 single male flies in 8 separate and EMPTY vials without food so that they would starve for a while as motivation to fight. After about 7 hours of no food, i unleash two random ones onto a similar fighting arena as the experiment used with a food cup with the same cornmeal medium.

[pose716]

ive been following this expirement but i need help. I got vials of wild-type drosophila melanogaster from Carolina reared on cornmeal medium. I tried to get this type of aggression for my experiment where im adding an ssri as a variable to see if it affects the aggressiveness of these flies, but they havent been very aggressive at all.

[wheeup]

they`re just playing the love game!!!

[tomokh]

This was probably the most amusing fly battle I ever saw. It's interesting that the fly just get pushed off rather than once they reach the edge, they fly away and come back.

[pizbox]

looks like peanut butter in a bottle cap is totally worth all that effort. hey, he's only got a day or two to live! FLY FIGHT!!!

[BionicGroin]

It looks like they're doing judo with 4 arms.

[kma122]

wouldve been a funny if a giant thumb came down and squished both at the end

[RLviddy]

Interesting! It does look territorial, as they keep pushing each other to the edge of the "wrestling ring," or perhaps they dated the same female. :-)

[cedar688]

awsome. in slowmotion we see how aggresive drosophila can be. they actually flatten eachother. these flies seem to be fighting like females (headbutting/pusshyness) whats going on?

[luckyspunk27]

all i wanna know is, WHO WON?!?!?!

[Chervyakov]

ohne arme keine kekse!

[pose716]

ajmccart, i think Dr. Dierick's work is really interesting and I would liek to use his work in an experiment maybe...ajmccart can u suggest some readings and articles that can help me develop a strong knowledge base for learnign about aggressiveness in fruit flies please??

[ajmccart]

Thanks for your interest!

I'd suggest going to pubmed . com, searching "Dierick HA" and looking up Dr. Dierick's most recent papers. He references all of the papers he considers important for his work. I assume you have access to journal articles, if not let me know.

[veemper]

intense battle.

[cocobeans142]

I noticed they don't care if a female goes on the food territory. =O

[stoatbinger]

What are they fighting for? Or did one spill the other's sugar solution

[ajmccart]

They fight for the territory.  Perhaps the territory is important because this is their food, as well as where females lay eggs . . .

[Sergionewyork]

Hi! interesting behairvour .... I am getting my master's degree in Biochemistry in New york.... where  is your lab?

[ajmccart]

Thanks for your interest! We are at The Neurosciences Institute in San Diego, CA. If you want to see more videos, look up "Dierick HA" in pubmed. . .the paper is published in Nature Genetics under the title "Molecular analysis of flies selected for aggressive behavior."

[christabone]

lol @ JWWells

Ralph is the man.

[JWWells]

How appropriate. The Greenspan Lab releases a video of... fly pushing.

[whdxgf]

wonderful! why these flies didn't fly away?

And,which lab u r in?Martin Heisenberg's?

[ajmccart]

They can fly away, but they don't want to; they want to win! I'm in the Greenspan lab.
