Figure 6From: Floral volatiles interfere with plant attraction of parasitoids: ontogeny-dependent infochemical dynamics in Brassica rapa Total volatile emission of vegetative and flowering plants before and after Pieris infestation. a Leaf volatiles emitted by vegetative plants (n = 11 pairs), b leaf volatiles emitted by pre-flowering plants, c leaf volatiles emitted by pre-flowering plants, and d floral volatiles emitted by flowering plants. Volatiles were collected for 5 h using super Q filters. Asterisks indicate significant increase of volatile emission after infestation (paired t test, P < 0.05).Back to article page
