A Bitter/Sweet Shift in Cockroach Defenses

A Bitter/Sweet Shift in Cockroach Defenses | Research from the NC Agricultural Research Service | Scoop.it
Some populations of roaches have evolved a highly effective strategy to avoid sweet-tasting poison baits, researchers say.
CALS Research, NCSU's insight:

CALS researchers Dr. Coby Schal, Dr. Jules Silverman & Dr. Ayako Wada-Katsumata report in the prestigious journal, Science, that roaches can change their taste chemistry, making usually appealing sweet food become bitter. So they avoid baits containing glucose. Result: Failed cockroach control!  Now we know why, and how they do it. The innovative research also has implications for control of other insects, such as mosquitoes.

CALS Research, NCSU's insight:

Dr. Coby Schal and postdoctoral researchers, Dr. Katalin Boroczky and Dr. Ayako Wada-Katsuma ask why cockroaches groom and find that the fastidious behavior sharpens their senses. The discovery may have implications for pest control.
