Mutant roaches evolve to avoid traps

Cockroaches may be evolving the ability to avoid common traps by developing an aversion to sugar.

A cockroach infestation in one's home can be a particularly nasty experience and require the services of an exterminator, but now it seems that some mutant German roaches are getting wise to the traps used to catch them and are now able to avoid them. The way they accomplish this is by no longer finding sugar palatable, the substance that is most commonly used as a bait on cockroach poisons.

While this mutation is not present on all cockroaches, it does exist and it appears to be getting more widespread. "It's very important, in terms of effective pest control," said study author Coby Schal. "It's not trivial. It's out there."

"Roaches that have been hard to trap may be a variety that find sugar doesn't taste quite so sweet as bait anymore, a study suggests."

Bugs are so alien looking to us, so not fuzzy and warm we see them as vile and disgusting but I'm pretty sure they think we are too. So, it's all good. Plus, I have a feeling that if things were the other way around the roaches would not have even a tiny fraction of tolerance for us. Viva le differance

Are the German roaches superior to other roaches, then? My house in PA was infested with them. They are harder to kill. I had to fumigate the whole house and be out of it for 24 hrs.

A shoe is a good short term solution but then their families are watching horrified as the family members guts spurt out which is really good motivation for a most heinous revenge of crawling on the sleeping body of the reaper waiting... just waiting for the lips to part.. a millimeter is all they need to poop In your mouth then crawl back to watch as you smack it down. They are disgusting creatures and I have a karmic pact with them... they shall only enter my house if they want to die. In which case I thank them for the trust and honor of being the chosen one before I kill them dead. I reall... [More]

Yeah I know, not all creepy crawlies look that nice but I do think deep in our subconscious, we're naturally wary of them because of how big they used to be (for our ancestors) and some believe spiders in those times would have been capable of hunting humans. I try to find the beauty in all living things, though it's not always easy.. Exhibit A... Spiders have a dangerous yet sexy quality even though they are very different from us. I often feel we are on the same side when it comes ... [More]

Shoes work real well. I have the same policy. They come I my house, they die. I had a Tom cat that would catch them and play with them until he killed them. He'd leave them lay where ever he was done with them. My wife and I would find them in the most interesting places. lol, Cats have the strangest sense of humor, don't they? I'm glad your tom cat didn't eat them... ugh.

Are the German roaches superior to other roaches, then? In their own tiny brains, that is the truth.

The benefits of a lifespan of only a one or two years certainly permits greater opportunity to evolve change and assure success of the species.
