Abstract

In 2003, an 8-year study was initiated to determine the impact of herbivores on three selected eastern cottonwood clones. The plantation, managed by MeadWestvaco, is located just north of Hayti, Pemiscot County, MO. Each clone was planted in 100 (10 x 10) tree plots. There was a total of 8 blocks, each of which contained all 3 clones (300 trees). Four of the eight blocks were not protected from defoliation (untreated) and the remaining four (treated) were treated with an insecticide to control the cottonwood leaf beetle (CLB) (Chrysomela scripta F.) and other incidental herbivores. The 8-year objective is to determine the overall losses and/or gains associated with controlling or not controlling defoliation caused primarily by the CLB.
