Title: Effects of genotype, elevated CO2 and elevated O3 on aspen phytochemistry and aspen leaf beetle Chrysomela crotchi performance

Author: Vigue, Leanne M.; Lindroth, Richard L.;

Date: 2010

Source: Agriculture and Forest Entomology. 12: 267-276.

Publication Series: Scientific Journal (JRNL)

Description: Trembling aspen Populus tremuloides Michaux is an important forest species in the Great Lakes region and displays tremendous genetic variation in foliar chemistry. Elevated carbon dioxide (CO2) and ozone (O3) may also influence phytochemistry and thereby alter the performance of insect herbivores such as the aspen leaf beetle Chrysomela crotchi Brown. The present study aimed to relate genetic- and atmospheric-based variation in aspen phytochemistry to C. crotchi performance (larval development time, adult mass, survivorship). The experiment was conducted at the Aspen Free-Air CO2 Enrichment (FACE) site in northern Wisconsin.

Keywords: carbon dioxide, FACE, herbivore performance, ozone, ozone-tolerance, phenolic glycosides, plant–insect interactions, Populus tremuloides, specialist, trembling aspen.
