| Abstract/Contents: | Presents research conducted to "address what role, if any, natural enemies play in population dynamics of the [annual bluegrass weevil (ABW)]." Explains that "the fear of visible damage has lead superintendents to rely heavily on the use of preventive chemicals for suppressing egg laying by adults. The overuse of preventive chemical pesticides is largely due to a poor understanding of the behavior and ecology of the weevil and a lack of alternative controls." Mentions the use of entomopathogenic nematodes (EPNs) as a potential method of ABW control. States that "EPNs are microscopic, non segmented roundworms that are obligate parasites of a diverse array of insects." Discusses laboratory and field trials, stating that researchers "have assayed several commercial and two endemic strains of EPNs against ABW in the laboratory and field with varying levels of success. Early laboratory data suggests that the adult stage is not very susceptible to EPNs, even under ideal conditions for nematode infection...[but] EPNs can be effective in reducing the number of larvae to below damaging levels." Reports that "EPNs applied...against late instar larvae demonstrated control comparable to chemical pesticides...Applications against the summer generation of larvae (end of July to early August) were not effective, likely due to the lethally high temperatures and dry conditions experienced after application." |
