Leaf consumption of beetles in feeding trials with leaves from plants used in free-flight experiments.

<p>In binary-choice feeding experiments each two leaflets derived from plants previously used in free-flight experiments were offered to individual beetles of <i>Cerotoma ruficornis</i> (A) and <i>Gynandrobrotica guerreroensis</i> (B) and leaf area consumption was determined. Pearson's correlations were calculated to evaluate effects of HCNp on leaf consumption.
