COMMUNITY AND ECOSYSTEM ECOLOGY Predator Abundance in Alfalfa Fields in Relation to Aphids, Within-Field Vegetation, and Landscape Matrix
We used multiple regression modeling to investigate the numerical response by the predatory insectsHippodamia convergensGuérin-Méneville,H. parenthesis (Say), and C. septempunctataL. (Coleoptera: Coccinellidae),Chrysoperla plorabunda (Fitch) (Neuroptera: Chrysopidae), and Nabis americoferus Carayon (Hemiptera: Nabidae) to aphids during 5 yr in three geographically separated alfalfa Þelds in eas...
متن کاملLocal and landscape drivers of predation services in urban gardens.
In agroecosystems, local and landscape features, as well as natural enemy abundance and richness, are significant predictors of predation services that may result in biological control of pests. Despite the increasing importance of urban gardening for provisioning of food to urban populations, most urban gardeners suffer from high pest problems, and have little knowledge about how to manage the...
متن کاملBiological control of cereal aphids in north america and mediating effects of host plant and habitat manipulations.
The predator and parasitoid fauna associated with cereal aphids is described, emphasizing the fauna associated with classical biological control efforts against the greenbug and Russian wheat aphid. We focus on literature from North America and include work from Europe and elsewhere when it is desirable to draw contrasts between approaches that affect cereal aphid biological control. Effects on...
متن کاملGut microbiomes of mobile predators vary with landscape context and species identity
Landscape context affects predator-prey interactions and predator diet composition, yet little is known about landscape effects on insect gut microbiomes, a determinant of physiology and condition. Here, we combine laboratory and field experiments to examine the effects of landscape context on the gut bacterial community and body condition of predatory insects. Under laboratory conditions, we f...
متن کاملSpecies identity dominates the relationship between predator biodiversity and herbivore suppression.
Agricultural pest suppression is an important ecosystem service that may be threatened by the loss of predator diversity. This has stimulated interest in the relationship between predator biodiversity and biological control. Multiple-predator studies have shown that predators may complement or interfere with one another, but few experiments have determined if the resulting effects on prey are c...
