“…Although some cropping patterns such as intercropping are practiced to protect highly erodable land from soil erosion, fertilizer management, or weed control (Vandermeer, 1989;Theunissen, 1994), they can also enhance insect predator populations through their contribution to habitat diversification (Alderweireldt, 1994;Theunissen, 1994;Mineau and Mclaughlin, 1996;Obrycki and Kring, 1998;Mensah, 1999;Parajulee and Slosser, 1999;Prasifka et al, 1999). Relay intercropping is a pattern that allows planting of one inter-crop species before another so that their life cycles partially overlap (Kass, 1978) and provide a predator reservoir before the arrival of key pests of the primary crop (Gold et al, 1990;Lys and Nentwig, 1992).…”

A 2-year study was conducted to evaluate the role of winter wheat, Triticum aestivum L., as a potential relay crop to conserve arthropod natural enemies and suppress cotton aphids, Aphis gossypii Glover, in seedling cotton. The results suggested that the natural enemies that moved from the adjacent wheat fields to cotton fields with the maturity and harvest of wheat could keep the cotton aphid population at the edges (0-4 m) of cotton fields under the action threshold of 100 aphids/m 2 . Data also suggested that the wheat strip served as a reservoir to conserve arthropod predators and ''relayed'' its predators to cotton when wheat matured and senesced.

“…Further, Fye (1972) asserted that the tolerance of grain sorghum to insect damage, coupled with its early maturation relative to cotton, virtually assured the movement of common predators into cotton. Later research by Fye and Carranza (1972), Robinson et al (1972aRobinson et al ( , 1972b, Massey and Young (1975), Lopez and Teetes (1976), and Prasifka et al (1999) supported the notion that grain sorghum contributes to pest suppression in cotton. To date, only Lopez and Teetes (1976) and Prasifka et al (1999) attempted to explicitly examine predator movement using mark-recapture techniques.…”

“…in the tropics), or a complement of crop types that senesce out of phase. In such situations, where spiders have the opportunity to balloon directly from a senescing crop to a young crop (Whitcomb & Bell, 1964;Burel & Baudry, 1995), the spatiotemporal pattern of cropping could be adjusted to minimise dispersal risk and thus enhance the scale of immigration into young crops (Parajulee et al, 1997;Prasifka et al, 1999).…”

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.
