“…Host tree vigor does not seem to influence G. hiambachiana infestation and damage rates (112,151), but a great deal of variation in resistance to G. hiambachiana exists among Populus selections. In Texas, native P. deltoides hybrids showed little resistance to G. hiambachiana attack (112,151), but a nonnative hybrid was resistant.…”

“…In Texas, native P. deltoides hybrids showed little resistance to G. hiambachiana attack (112,151), but a nonnative hybrid was resistant. IMHFS in the Mississippi Delta showed geographic variation with respect to G. hiambachiana infestation levels, and adequate control was achieved with chemical insecticides (131).…”

“…This multivoltine pest has two and up to five generations per year in Iowa (96) and the Mississippi Delta region (97), respectively. The life history and phenology of the insect have been described in the South (97,112) and Midwest (96). Larval feeding causes a shortening of internodal distance and increased forking, stem and limb breakage, and mortality of terminal and lateral shoots, which can lead to loss of apical dominance, thus reducing tree growth and form (131,139,151).…”

▪ Abstract Increasing demand for wood and wood products is putting stress on traditional forest production areas, leading to long-term economic and environmental concerns. Intensively managed hardwood forest systems (IMHFS), grown using conventional agricultural as well as forestry methods, can help alleviate potential problems in natural forest production areas. Although IMHFS can produce more biomass per hectare per year than natural forests, the ecologically simplified, monocultural systems may greatly increase the crop's susceptibility to pests. Species in the genera Populus and Salix comprise the greatest acreage in IMHFS in North America, but other species, including Liquidambar styraciflua and Platanus occidentalis, are also important. We discuss life histories, realized and potential damage, and management options for the most economically influential pests that affect these hardwood species. The substantial inherent challenges associated with pest management in the monocultural environments created by IMHFS are reviewed. Finally, we discuss ways to design IMHFS that may reduce their susceptibility to pests, increase their growth and productivity potential, and create a more sustainable environment.
