  1. Reduce fertilizer, pesticide or herbicide use generally

    A controlled study as part of the Boxworth project comparing arable farmland with high and reduced pesticide inputs over five years in Cambridgeshire, UK (Vickerman 1992) (same study as (Fletcher et al. 1992)) found that the abundance of invertebrate herbivores, carnivores and parasitoids tended to be higher in areas with reduced pesticide applications, whereas detritus-feeding invertebrates did not differ with treatment. On average, total numbers of herbivores were 50% lower, predators 53% (39-70%) lower and parasitoids 39-79% lower in the conventional area compared to the reduced pesticide areas. Numbers varied with year, and numbers of some taxa were higher in conventional areas in some years. Numbers of detritus-feeders did not differ significantly between treatments. There were two treatment areas, one with conventional and the other reduced pesticide applications (selective insecticides and slug/snail pesticides). Invertebrate density was sampled in the middle of each field using a Dietrick vacuum sampler at intervals of 7-10 days between mid-April and harvest. Each sample comprised five sub-samples (each 0.09 m²) taken 10 m apart.
