“…Material was collected from late April until early October from a variety of habitats including roadside ditches, pond and lake margins, and extensive marshes. In addition to natural stands, observations and collections were made on a regular basis from cultivated stands (Andrews et al 1981;Pratt et al 1982Pratt et al ) in 1980Pratt et al and 1981Pratt et al , and to a lesser extent in 1982Pratt et al and 1983. Emphasis was placed on insects using upper leaves and stems; insects associated with the inflorescence or roots are not considered here.…”

Studies were conducted to identify the common phytophagous insects that feed on Typha spp. (cattails) in Minnesota and to quantify the extent of insect herbivory in natural stands. Six lcpidoptcrans and two aphids wcre noted to feed on Typha shoots. The most common herbivorous inscct in natural stands was the miner-borer Archanara oblonga Grt. (Lepidoptcra: Noctuidae). The noctuid Bellura obliqua Walk. was the most common miner-borer in newly planted cultivated stands. Nineteen Typha stands were sampled in midsummer to quantify the extent of inscct herbivory. Overall, about 15 percent of shoots showed some evidence of insect herbivory. Eight percent of damaged shoots had damage to upper leaves attributable to lepidopteran miner-borers (chiefly A . oblonga). Five percent of shoots had stem damage. Less than one percent of shoots wcre damaged by Icaf-chewing insects. Typha latifolia stands were more heavily infested than those of T . angustifolia or T. glauca. Stands located in southern Minnesota were much more heavily infested than those in northeastern Minnesota. Water depth and shoot nitrogen content did not have a significant effect on infestation rate. The majority of infested shoots suffered minor damage (i.e., 120Y0 reduction in leaf area). Much of the damage caused by lepidopteran miner-borers was indirect. Although natural Typha stands and small cultivated plots are occasionally susceptible to heavy infestations of phytophagous insects, it seems unlikely that insect pests would hamper Typha bio-energy production in Minnesota.

“…The potential cultivation of Typha as an energy crop is under study in Minnesota, and young planted stands are sometimes liable to considerable insect damage (Andrews et al 1981;Pratt et al 1982).…”

This report summarizes the progress and research accomplishments of the SERI Biomass Program during FY 1983. The SERI Biomass Program consists of three elements: Aquatic Species, Anaerobic Digestion, and Photo/ Biological Hydrogen. The program is funded through the Biomass Energy Technology Division of the Department of Energy (Beverly J. Berger, Director). SERI has adopted several strategies to ensure that the data developed by the Biomass Program is transferred to other researchers and to the private sector. Involvement of industry in the early stages of research and development will help direct the program toward the development of operational systems as well as promote the transfer of the technical data base to private industry. Publication of data in peer-reviewed journals, in SERI publications, and proceedings of regular contractor review meetings will make SERI-sponsored research available to the scientific community in the public and private sectors.
