Non-consumptive effects stabilize herbivore control over multiple generations.
PLoS ONE, 2020 Understanding the factors that influence predator-prey dynamics requires an investigation of oscillations in predator and prey population sizes over time. However, empirical studies are often performed over one or fewer predator generations.

Primary parasitoid and hyperparasitoid guilds (hymenoptera) of grain aphid (Sitobion avenae F.) in northern Poland [PDF]
Archives of Biological Sciences, 2015 The aim of this study was to determine and compare the guilds of parasitic Hymenoptera associated with the grain aphid on rye and winter wheat in northern Poland. Of the seven species of primary parasitoids (Braconidae: Aphidiinae, Aphelinidae),

Do interactions between plant roots and the rhizosphere affect parasitoid behaviour? [PDF]
, 2004 Multitrophic interactions are powerful forces shaping the structure of living communities. Plants encounter a great diversity of organisms in their environment: some of these interactions are beneficial (e.g. symbiotic fungi and insect pollinators) while

Plant Protection Science, 1999 From the obtained results we can note that the parasitoids in our experiments in 1 997 and 1998 had considerable influence on decline of aphids population density, at which the percent of parasitization in milk maturity stage of wheat was from 2.7 to 35%.

Dynamics of Insects and Their Facultative Defensive Endosymbiotic Bacteria: A Simulation Model. [PDF]
Ecol EvolAphids host endosymbionts protect them against attacks from parasitoids, leading to potential reduction in the efficacy of biological control against these crop pests. We developed a Monte Carlo simulation model to examine changes in levels of endosymbiont infection in an insect population in the presence of parasitoids attacking them over several ...

Combining lacewings and parasitoids for biological control of foxglove aphids in sweet pepper [PDF]
, 2016 The role of natural enemy diversity in biological pest control has been debated in many studies, and understanding how interactions amongst predators and parasitoids affect herbivore populations is crucial for pest management.

Plant Protection Science, 2003 During 1997-1999, occurrence of hymenopteran parasitoids of cereal aphids was observed in different localities in Slovakia. Altogether, seven species of aphid parasitoids were recorded.

Aphidius ervi venom regulates Buchnera contribution to host nutritional suitability
Journal of Insect Physiology, 2023 The association between the pea aphid, Acyrthosiphon pisum (Harris) (Homoptera: Aphididae), and the endophagous parasitoid wasp Aphidius ervi Haliday (Hymenoptera: Braconidae) offers a unique model system for studying the molecular mechanisms underlying the complex interactions between the parasitoid, its host and the associated primary symbiont. Here,

Why is there no impact of the host species on the cold tolerance of a generalist parasitoid? [PDF]
, 2017 For generalist parasitoids such as those belonging to the Genus Aphidius, the choice of host species can have profound implications for the emerging parasitoid. Host species is known to affect a variety of life history traits.

European Journal of Entomology, 2002 The aphid parasitoid Aphidius ervi was collected and subsequently reared on Sitobion avenae on wheat or Acyrthosiphon pisum on alfalfa. Parasitoids from both origins were exposed in an olfactometer to alfalfa or wheat volatiles after plant experience ...
