Can We Disrupt the Sensing of Honey Bees by the Bee Parasite Varroa destructor?
Figure 5
Detailed evaluation of the long-term inhibitory effect of the most active compounds.
The effect of 0.1 µg cy{4,1} (A) or 3b{2,2} (B), with and without a simultaneous stimulus of the headspace volatiles from 5 nurse bees, on the electrophysiological response of the Varroa foreleg. The data are normalized values (%, average+SE): bars marked by different letters are significantly different, ANOVA repeated measures, p<0.05, p<0.05, n = 6. The longevity of the inhibitory effect of 0.1 µg cy{4,1} (C) or 0.1 µg 3b{2,2} (D) on Varroa foreleg electrophysiological responses. The time interval between the mixed stimulus (Bee + compound) and the pure bee stimulus was varied. Values are normalized against the response to air (%, average+SE): bars marked by different letters are significantly different, ANOVA repeated measures, p<0.05; n = 6.
