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.

Bacteria in the guts of honeybees are highly resistant to the antibiotic tetracycline, probably as a result of decades of preventive antibiotic use in...

 

Yale University researchers find that routine oxytetracycline use to prevent foulbrood appears to have caused genetic adaptation in bacteria in the honeybee.

 

The resistant bacteria were not found in honey, however.
