1990). Access by birds and small mammals stealing the contents of the traps is prevented (Briggs 1960, Mitchell 1963a), as is their consumption of toxic preservatives (Marshall & Doty 1990, Hall 1991). Wire barriers have also been used to prevent the accidental capture of small vertebrates in traps. Unfortunately roofs cause bias in the catches of pitfall traps (Joose 1965, Morrill 1975, Baars 1979). The use of transparent materials for roof coverings, however, minimizes the influence of roofs on the catches of invertebrates (Joose 1965, Baars 1979).

Maggot Tetanops myopaeformis (Diptera: Otitidae) in cultivated fields (Whitfield & Grace 1985). For large-scale sampling of insects across whole fields, plough transects have been used. This is simply where a tractor plough cuts a furrow and the insect larvae exposed are counted and expressed as numbers per unit length of furrow. The technique has generally been used in grassland where the destructive nature of the method is not too much of a problem (Roberts et al. 1982a, East & Willoughby 1983).
