We all know that the most sly and sneaky creepy crawler out there is the cockroach. This bug will eat our pizza or snickers bar if open and left out; it will even raid our pantries and refrigerators. Over a span of many years this bug has put up quite a resistance in the war against mankind. The roach is one of the most exterminated bugs by pest control professionals, but in the 1990’s in Florida, some of the exterminator’s tricks stop working. This was because the roaches developed a trick of their own; ditching their sweet tooth.
One of the professional tactics used against cockroaches is baiting them with a sweet, sugary poison. In the 90’s when this bait stopped working, researchers started speculating about this seemingly invincible pest. How had the bug avoided the sweet scent and taste of the concoction? Researchers from Raleigh’s North Carolina State University, Ayako Wada-Katsumata, Jules Silverman, and Coby Schal looked into that very question.
Using the common German cockroach, researchers studied the reason for this change in roach behavior. Roaches use taste hairs all over their bodies instead of taste buds to taste their food. Researchers focused on the taste hairs around their mouths and two types of nerve cells that transmit signals to the brain. One of these transmits the taste of bitterness, while the other transmits the taste of sweetness.
