Behavioral responses of Chrysomela populi to isoprene emitting (IE) and non-emitting (NE) poplar. Response of C. populi adults (a) to volatiles released by IE and NE plants in a Y-tube olfactometer and response of larvae (b) in feeding choice-experiments. Bars represent the overall percentages of beetles choosing either of the odor sources; numbers in bars are the total numbers of beetles choosing that odor source. The percentage of insects not choosing is shown in pie charts. Binomial tests showed no significances between the choices
