Gustatory Perception and Fat Body Energy Metabolism Are Jointly Affected by Vitellogenin and Juvenile Hormone in Honey Bees

Gene knockdown effect on sucrose responsiveness in 7-day-old bees.

The gustatory responsiveness score (GRS) was measured in the laboratory using the bees' proboscis extension response (PER). High GRS shows that bees responded to low sucrose concentrations, indicating a high gustatory sensitivity. Double knockdown bees (vg-/usp-) showed significantly increased gustatory responsiveness (Mean ± s.e., n = 33–65, p<0.05).
