Cockroaches lose their 'sweet tooth' to evade traps
damnedahhh


American scientists found that thecockroaches had a "reorganised" sense of taste, making them perceive the glucose used to coat poisoned bait not as sweet but rather as bitter.

"We released them into a small arena where there were two identical food sources," he explained. "If they didn't communicate, we would expect that they should just distribute on the two food sources equally."

But the majority of the hungry cockroaches (Blattella germanica) fed solely on one piece of food until it was all gone.

By following individual insects, it also emerged that the more of cockroaches there were on one piece of food, the longer each one would stay to feed.
Cockroaches on food source The hungry insects appear to make a collective decision about what to eat

"We don't know how they communicate, but we know they're using chemicals," Dr Lihoreau explained. "That will be the next step - to find the chemicals involved in the communication.

"These observations coupled with simulations of a mathematical model indicate that cockroaches communicate through close contact when they are already on the food source."

Intelligence defined by man is solving puzzles.

Intelligence defined by nature is awareness.
