Delay mowing or first grazing date on pasture or grassland Natural Pest Control

A replicated, randomised, controlled trial in 1973-1975 on a tall oatgrass Arrhenatherum elatius-dominated grassland in Cambridgeshire, UK (Morris 1981a) (same study as Morris 1979, Morris 1981b) found that delaying mowing resulted in significantly fewer leafhoppers (Auchenorrhyncha). There was an average of 4,546 individuals/plot in plots cut in May compared to 1,906 individuals in plots cut in July. Uncut plots had similar numbers of leafhoppers (5,666 individuals) to plots cut in May. There was no difference in the number of species between cutting treatments. Four cutting treatments (uncut, May cut, July cut, May and July cuts) were replicated four times and randomly allocated to plots of 16 x 12 m. Invertebrates were sampled in October 1972-December 1975 using a D-Vac suction sampler.
