FIGURE 3.

Low hemolymph glucose concentration in honeybees following epinastine treatment depends on the feeding state. (A) The hemolymph glucose level of bees fed with 30% (w/v) sucrose solution (0.88 M) to satiation (sated PBS) was higher than that of hungry bees that remained unfed (hungry PBS). Sated and epinastine-treated bees showed a lower hemolymph glucose concentration than sated control animals (sated EPI vs. sated PBS). Epinastine-treatment did not affect hungry bees (hungry EPI vs. hungry PBS). (B) The glucose level in the hemolymph of bees fed with 4 μl 30% (w/v) sucrose solution (0.88 M) (1 drop PBS) was higher than that of hungry bees (hungry PBS). Epinastine-treatment did not affect bees fed with 4 μl 30% (w/v) sucrose solution (0.88 M) (1 drop EPI vs. 1 drop PBS) and hungry bees (hungry EPI vs. hungry PBS). ^∗p < 0.05. Number of bees appears in brackets.
