“…Previous studies reported that weeds served as alternative sources of prey, and on which Orius spp. and thrips populations interacted very well, in Spain (Lacasa et al 1995) and in Japan (Kakimoto et al 2006). In the present study, the presence of Orius spp.…”

The influence of weedy field strips on the abundance patterns of western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), and predatory bugs of Orius spp. (Hemiptera: Anthocoridae), on faba bean and on weeds was investigated in Adana province, Turkey, during 2005-2006. There were two treatments: in one treatment, weeds at the margins and inside the plots were regularly controlled by tillage; in the other treatment no weed control was done. Thrips and Orius were sampled by beating faba bean plants and weeds. Orius niger (Wolff) was the most abundant predatory insect species in faba bean and flowering weeds, with numbers of adults and nymphs significantly greater in plots with weedy margins than in weed-free plots. Flowering weeds did not contribute to the abundance of F. occidentalis on faba bean. Abundance of adults of Orius spp. did not coincide with the abundance of F. occidentalis on faba bean or weeds. There were significant negative associations for numbers of Orius spp. among faba bean and the weed species Lamium amplexicaule L. or Sinapis arvensis L. (P<0.05), indicating movement of Orius individuals from the weeds to faba bean during March-April. Finally, faba bean and weeds may provide some benefits to predators, such as nectar, pollen, shelter and egglaying sites rather than as sources of insect prey. Cultivation of faba bean could be useful for conservation and augmentation of beneficial insects, including Orius spp. Furthermore, field margins bearing flowering weeds such as S. arvensis and L amplexicaule should be protected against destructive management practices, because they host considerable numbers of the Orius species.

“…Orius sauteri is an important predator of spider mites in China and plays an essential role in suppressing spider mites populations in various crops (Yan, 1988;Du & Yan, 1994, 1995. However, the population trends of O. sauteri are synchronized with the abundance of thrips rather than with spider mites (Kakimoto et al, 2005). This, combined with the very high preference of O. sauteri for F. occidentalis demonstrated in the present study, could arouse concern that the recent invasion of Western Flower Thrips into China may have consequences for natural regulation and ⁄ or inoculative biocontrol of spider mites.…”

Prey preference of polyphagous predators plays an important role in the suppression of various species of pest insects. In this study, the prey preference of Orius sauteri (Poppius) (Heteroptera: Anthocoridae) between deutonymphs of Tetranychus urticae Koch (Acari: Tetranychidae) and second instars of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), and the influence of spider mite density on the preference were examined in the laboratory in three‐dimensional set‐ups at 25 ± 1 °C and 70 ± 5% r.h. The results showed that the predatory bug in the presence of equal densities of the two prey species had a clear preference for thrips (preference index β: 0.86 ± 0.02), consuming 7.2 thrips larvae and 1.5 spider mite deutonymphs during the experimental periods of 6 h. The number of thrips consumed by O. sauteri did not change when the density ratio of thrips to spider mites was decreased from 1:1 to 1:5. Predation on spider mites increased when their ratio to thrips increased, but the disproportionate predation (i.e., the functional response) of O. sauteri towards spider mites resulted in a linear increase in the preference for F. occidentalis. The possible implications of these findings for the suppression of spider mites by O. sauteri in relation to the recent invasion of F. occidentalis into China are discussed.
