Cottonwood Leaf Beetle

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.

Willow Leaf Beetle

An artificial diet was developed for laboratory rearing of the cottonwood leaf beetle, Chrysomela scripta F., and the imported willow leaf beetle, Plagiodera versicolora (Laicharting). To reduce microbial contamination of the media, procedures were developed for separating egg masses and sterilizing egg surfaces. Cottonwood leaf beetle larvae reared from neonate to adult on this artificial diet had greater mortality, took longer to develop, and were smaller than larvae reared on fresh poplar foliage. Adult longevity was similar for both diet-and foliage-reared larvae. Survival and adult fresh weight of imported willow leaf beetle larvae reared on the artificial diet were similar to those of cohorts reared on fresh poplar foliage. However, individuals reared on artificial diet took longer to develop and produced shorter-lived adults than cohorts reared on foliage. Larvae of both species would not eat fresh foliage after being fed on the artificial diet. Adults of both species maintianed on the artificial diet laid few eggs but resumed normal oviposition when fed fresh foliage. This artificial diet proved useful for rearing larvae and maintaining adults during periods when fresh foliage was limited.

Water Contents

AbstractChrysomela scripta Fabricius adults showed a feeding preference for the youngest, most succulent leaves of tissue-cultured Populus × euramericana. Larvae fed equally on all leaves with water contents greater than 73%. Larvae chose shoot bark for feeding after all leaves with water contents greater that 70% had been consumed. Larvae reared on immature foliage had shorter developmental times and higher prepupal weights than those reared on mature foliage.
