E. Wajnberg, Editeur scientifique ; C. Bernstein, Editeur scientifique ; J. Alphen, Editeur scientifique | Malden [US] : Blackwell | 2008

K. Rauwald ; A. Ives | 2001In annual or periodically harvested crops, biological control of pests is aided if natural enemy populations rapidly recover within fields following disturbances. Here, we show that the life history of parasitoids may facilitate their recovery w[...]

J. Ferrari ; C. Muller ; A. Kraaijeveld ; H. Godfray | 2001The potential rate of evolution of resistance to natural enemies depends on the genetic variation present in the population and any trade-offs between resistance and other components of fitness. We measured clonal variation and covariation in pe[...]

S. England ; E. Evans | 1997The ability of parasitoids to attack their hosts may be influenced by the availability of adult food sources such as homopteran honeydew. To test this hypothesis for the wasp Bathyplectes curculionis (Thomson), a parasitoid of the alfalfa weevil[...]

R. Hufbauer ; S. Via | 1999The evolution of associations between herbivorous insects and their parasitoids is likely to be influenced by the relationship between the herbivore and its host plants. If populations of specialized herbivorous insects are structured by their h[...]

R. Hufbauer | 2001In insect host-parasitoid systems, successful immune responses of the host kill the parasitoid, and successful development of the parasitoid will kill the host. Thus, hosts and their parasitoids can exert strong selection on each other that may [...]

A. Chau ; M. Mackauer | 1997We examined the dropping behaviour of the pea aphid, Acyrthosiphon pisum (Harris), feeding on broad-bean plants in the laboratory. Aphid responses to foraging and oviposition by females of Monoctonus paulensis (Ashmead) were instar-specific and [...]

E. Evans ; S. England | 1996The population dynamics of insect pests in agroecosystems may often be linked to those of other phytophagous species through the foraging activities of natural enemies; these indirect interactions provide both opportunities and challenges for bi[...]

P. Christiansen-Weniger ; J. Hardie | 2000Wing formation in presumptive alate morphs (virginoparae and males) was observed for the pea aphid, Acyrthosiphon pisum, exposed to attack by the parasitoid, Aphidius ervi, at different stages of host development. Morphological abnormalities in [...]

I. Williams ; T. Jones ; S. Hartley | 20011. Both resources and natural enemies can influence the distribution of a herbivore. The ideal free distribution predicts that herbivores distribute themselves to optimise utilisation of resources. There is also evidence of herbivores seeking ou[...]
