Journal ArticleDOI
Biodiversity and biocontrol: emergent impacts of a multi-enemy assemblage on pest suppression and crop yield in an agroecosystem
TL;DR: Empirical evidence is presented that increasing the richness of a particular guild of natural enemies can reduce the density of a widespread group of herbivorous pests and, in turn, increase the yield of an economically important crop.
Journal ArticleDOI
Detection of a colonizing, aquatic, non-indigenous species
TL;DR: Results of this study suggest that early detection of colonizing, aquatic NIS may be optimized through use of a risk-based sampling design, combined with high sampling intensity in areas deemed most vulnerable to invasion, rather than less intensive sampling at a wider array of sites.
Journal ArticleDOI
Intraguild predation on the parasitoid Aphidius ervi by the generalist predator Harmonia axyridis: the threat and its avoidance
Matthew H. Meisner,Jason P. Harmon,Jason P. Harmon,Chad T. Harvey,Chad T. Harvey,Anthony R. Ives +5 more
TL;DR: Despite a risk of intraguild predation by H.’axyridis, this study suggests that A.“ervi may be able to mitigate this risk by altering its behavior in response to chemical cues.
Journal ArticleDOI
Pea aphid dropping behavior diminishes foraging efficiency of a predatory ladybeetle
TL;DR: It is suggested that the high rates of dropping induced by H. axyridis and the subsequent decrease in H.Axyridis foraging efficiency may partially explain why H. Axyridis is less effective at controlling pea aphids than it is at controlling other aphid species that do not drop.
Journal ArticleDOI
Intraguild predation of parasitoids by Solenopsis invicta : a non-disruptive interaction
Chad T. Harvey,Micky D. Eubanks +1 more
TL;DR: The results of this study suggest that the presence and conservation of multiple natural enemies may result in sustained pest suppression in agroecosystems, even complex systems containing many species of natural enemies including strong intraguild predators such as S. invicta.
