Delay mowing or first grazing date on pasture or grassland
A replicated, randomised, controlled trial in 1973-1975 on a tall oatgrass Arrhenatherum elatius-dominated grassland in Cambridgeshire, UK (Morris 1979) (same study as Morris 1981a, 1981b) found delaying the mowing date resulted in fewer bugs (Heteroptera). There were more bugs in plots cut in May only (averaging 176 individuals/plot) than plots cut in July only (52 individuals). Uncut plots had 288 individuals/plot. 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.
