“…This would decrease the amount of extraneous, nontarget predator proteins present in the sample. Gut and crop dissections have been used before, primarily with large predator species that are relatively easy to dissect (Dempster, 1960;Sunderland et al, 1987;Hagler and Cohen, 1990;Symondson and Liddell, 1995). However, most pink bollworm egg predators are too small and soft bodied to be easily dissected (Hagler and Naranjo, 1994a,b).…”

“…The response to prey spatial heterogeneity, the aggregation, aphid and mildew preferences were studied by many authors (Bryen and Wratten 1985;Sunderland et al 1987;Dennis et al 1991;Good and Giller 1991). Several species aggregated in patches of aphids, and they presented a positive numerical response to the high aphid densities (Bryen and Wratten 1985).…”

“…Under laboratory conditions the average aphid consumption was 1 mg daily for many of the species, which is more than 34% of their body weight. In gut-dissection work carried out by Sunderland et al (1987) three categories of food, other than aphids, were identified in the diet of the Tachyporus spp. : non-aphid arthropods, rusts and non-rust fungi.…”

Abstract:The dominance, diversity and activity density of rove beetles were studied in Central European apple and pear orchards. Altogether 6 877 individuals, belonging to 271 species and 11 subfamilies were collected. Thirteen species presented a relative abundance from 9 to 2% and amounted to almost 56% of all staphylinids recorded. In dominance order they were: Dinaraea angustula (Gyllenhal), Omalium caesum Gravenhorst, Drusilla canaliculata (F.), Sphenoma abdominale Mannerheim, Palporus nitidulus (F.), Xantholinus linearis (Olivier), Dexiogya corticina (Erichson), Coprochara bipustulata L., Mocyta orbata (Erichson), Oligota pumilio Kiessenwetter, Xanthlinus longiventris (Olivier), Tachyporus hypnorum (F.) and Pycnota vicina (Kraatz). The alpha diversity of staphylinids for different environmental conditions was relatively similar but the Shannon-Weiner Index (H) was higher than of other similar studies. However, the activity density was higher in pear, in sand and in abandoned plantations; under different environmental conditions this could not be considered uniform in time. After the cumulative studies on the population dynamics, one can conclude that the highest number of species can be found in spring and in summer. Species D. canaliculata and P. nitidulus presented the similar seasonal dynamics in orchards located in different environmental areas, while O. caesum had the same activity density both in apple and pear orchards.

“…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.
