Abstract
AbstractAdults and larvae of the cottonwood leaf beetle, Chrysomela scripta Fab., defoliated tissue cultured Aigeiros (Populus × euramericana (Dode) Guinier) subclones and destroyed apical tips. Fecundity was 510 ± 153 eggs . Four generations occurred between May and September in southern Wisconsin. Maximal insect numbers and damage occurred in the third generation. The minimal developmental threshold was 10.8 °C with a mean 257 ± 26 day-degree (°C) required per generation. Important biological control agents included Coleomegilla maculata, which consumed up to 25% of the eggs, and Shizonatus latus, a pteromalid parasite, which destroyed up to 26% of the pupae.
