Abstract/Contents: | "The effects of applying nitrogen to a perennial ryegrass sward were studied in relation to the size and nature of populations of dipterous stem-bores. Two levels of both ammonium sulphate and calcium nitrate were applied to the sward. Larvae were more numerous in the plots treated with high levels of nitrogen regardless of the form applied. Also, there were more larvae in the plots treated with ammonium sulphate than in those treated with calcium nitrate. A limited range of stem-borer species predominated. These were Oscinella vastator, two forms of O. frit and Geomyza tripunctata. Stem-borer species were distributed differently between plots receiving high and low nitrogen levels; G. tripunctata occurred almost exclusively on plots receiving high nitrogen applications while O. vastator was more frequent in those receiving low levels of nitrogen." |
