<i>Choristoneura fumiferana</i> larval development traits of lines feeding on medium and low quality diet for four generations and then fed the same and the opposite diet.

<p>Mean pupal weight, development time and growth rate (±SE) of females whose parents (i.e. parental diet) fed medium (dark grey) or low (white) quality diet, and males whose parents fed medium (black) or low (light grey) quality diet. The first four bars in each graph represent larval development traits of lines feeding on medium quality diet and the other four represent lines feeding on low quality diet (i.e. offspring diet). Also shown is the number of larvae per treatment and sex.
