“…Out of the 99 analyses presented here that had a sample size of more than eight, 73 comparisons showed no significant treatment effect and 0.67 , R , 1.5. Those groups that were found to be largely insensitive to the difference in herbicide management between GMHT and conventional crops tended to be generalist predators, such as the Carabidae (Thiele 1977) and spiders (Sunderland et al 1986), which are not wholly dependent on the weed flora.…”

The effects of the management of genetically modified herbicide-tolerant (GMHT) crops on the abundances of aerial and epigeal arthropods were assessed in 66 beet, 68 maize and 67 spring oilseed rape sites as part of the Farm Scale Evaluations of GMHT crops. Most higher taxa were insensitive to differences between GMHT and conventional weed management, but significant effects were found on the abundance of at least one group within each taxon studied. Numbers of butterflies in beet and spring oilseed rape and of Heteroptera and bees in beet were smaller under the relevant GMHT crop management, whereas the abundance of Collembola was consistently greater in all GMHT crops. Generally, these effects were specific to each crop type, reflected the phenology and ecology of the arthropod taxa, were indirect and related to herbicide management. These results apply generally to agriculture across Britain, and could be used in mathematical models to predict the possible long-term effects of the widespread adoption of GMHT technology. The results for bees and butterflies relate to foraging preferences and might or might not translate into effects on population densities, depending on whether adoption leads to forage reductions over large areas. These species, and the detritivore Collembola, may be useful indicator species for future studies of GMHT management.

“…The precise effect of spider predation on a pest population will vary according to which other factors are influencing the rate of pest increase at the time. Webmaking linyphiid spiders caused a peak mortality of 31 cereal aphids (Sitobion avenae (F.)) m −2 day −1 in a field of winter wheat (Sunderland et al, 1986), and it was estimated that, under the conditions prevailing at the time, predation by these spiders would have reduced peak aphid density by 37% (Fraser, 1982). De Barro (1992) showed that an 18 fold decrease (3.6 down to 0.2 per 195 cm 2 ) in the density of lycosid and linyphiid spiders inside enclosures in a perennial grass pasture caused a 16 fold increase in cereal aphid (Rhopalosiphum padi (L.)) density.…”

A review of the literature showed that spider abundance was increased by diversification in 63% of studies. A comparison of diversification modes showed that spider abundance in the crop was increased in 33% of studies by 'aggregated diversification' (e.g. intercropping and non-crop strips) and in 80% of studies by 'interspersed diversification' (e.g., undersowing, partial weediness, mulching and reduced tillage). It is suggested that spiders tend to remain in diversified patches and that extending the diversification throughout the whole crop (as in interspersed diversification) offers the best prospects for improving pest control. There is little evidence that spiders walk in significant numbers into fields from uncultivated field edges, but diversification at the landscape level serves to foster large multi-species regional populations of spiders which are valuable as a source of aerial immigrants into newly planted crops. There are very few manipulative field studies where the impact of spiders on pests has been measured in diversified crops compared with undiversified controls. It is encouraging, however, that in those few studies an increased spider density resulted in improved pest control. Future work needs are identified.

“…This species was also reported as the most abundant spider species in North Island pasture (Topping & Lövei 1997) and Canterbury pasture (McLachlan & Wratten 2003). Tenuiphantes tenuis is also common in agroecosystems in England and other European countries (Sunderland et al 1986;Topping & Sunderland 1994b;Sunderland 1996;Topping & Lövei 1997). Sunderland (1996) reviewed the population ecology of T. tenuis and stated that it had considerable biological control potential for cereal pests.…”

“…De Barro (1992) found that lycosid and linyphiid spiders were an important factor in controlling cereal aphid (Rhopalosiphum padi (L.)) numbers in irrigated perennial grass pasture. Aphids comprise a major part of the prey of harvestmen (e.g., Leathwick & Winterbourne 1984) and spiders in cereal fields (e.g., Sunderland et al 1986Sunderland et al , 1987Nyffeler & Benz 1988a,b) and the spiders and harvestmen found in New Zealand crops and pasture may contribute to reductions in pest populations.…”

“…Several studies have shown that aphids are an important prey of spiders in cereal fields (e.g., Sunderland et al 1986Sunderland et al , 1987Nyffeler & Benz 1988a,b). Knowledge of spider species richness and population densities, as well as factors that influence these parameters, is the first step in understanding the potential contribution of spiders to the biological control of pests such as aphids.…”

As an initial step in assessing the impact of spiders and harvestmen as biological control agents for insect pests of arable crops, the population density and species richness of spiders and harvestmen were examined in a range of cereal crops and grasses at two sites in Canterbury, New Zealand, in 1996, and 1999 using a ground suction sampler. Twenty spiders (Order Araneae) and one harvestman (Order Opiliones) were identified from the grass and cereal samples. Thirteen were endemic species. Population densities were estimated in ryegrass, fescue, cocksfoot, prairie grass, wheat, and barley. Greatest population density and species richness were found in fescue and ungrazed ryegrass, in which mean densities of up to 180.8 spiders and harvestmen per square metre were recorded. Estimates of density and species richness were much higher in grasses than in cereals. The introduced linyphiid spider Tenuiphantes tenuis (Blackwall), comprised over half of the spiders and harvestmen sampled. Other commonly found species were the introduced money spider (Erigone wiltoni Locket), and the endemic wolf spider Anoteropsis hilaris (L. Koch). The introduced harvestman Phalangium opilio L. was also common.
