High hymenopteran parasitoid infestation rates in Czech populations of the Euphydryas aurinia butterfly inferred using a new molecular marker [PDF]
Journal of Hymenoptera ResearchWe apply a molecular approach to quantify the level of hymenopteran parasitoids infestation in the larvae of the marsh fritillary (Euphydryas aurinia), a declining butterfly species, in western Bohemia, Czech Republic, in two subsequent years.

Pest Management Science, EarlyView.Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Pest Management Science, EarlyView.Host‐associated volatiles mediate host location in Cephalonomia tarsalis, with faecal odours from fourth‐instar larvae, particularly 1‐pentadecene, attracting females and supporting the biological control of stored‐product pest beetles. Abstract BACKGROUND Understanding how parasitoids locate their hosts is essential for improving the effectiveness of ...

The effect of the aphid sex pheromone on the aphid Myzus persicae and its parasitoid Aphidius colemani [PDF]
, 2012 Aphids remain an enormous threat to the sustainability of crops in glasshouse and field environments around the world. It is known that the aphid sex pheromone is used as a kairomone by its natural enemies, such as parasitoids. The focus of this research

The influence of aphids and honeydew on the leaving rate of searching aphid parasitoids from wheat plants [PDF]
, 1992 Dispersal cages were used to investigate the effects of aphids and treatment with artificial honeydew on the leaving rate of searching females of the parasitoid Aphidius rhopalosiphi from groups of wheat plants. Parasitoids which flew away from groups of

Bifurcation and Chaos in a Parasitoid-Host-Parasitoid Model
International Journal of Modern Nonlinear Theory and Application, 2018 This paper discusses a parasitoid-host-parasitoid ecological model and its dynamical behaviors. On the basis of the center manifold theorem and bi-furcation theory, the existence conditions of the flip bifurcation and Neimark-Sacker bifurcation are derived. In the end of the paper, some typical numerical experiments are performed, which illustrate that

Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat
Pest Management Science, EarlyView.Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

Revenge of the host: Cannibalism, ontogenetic niche shifts, and the evolution of life-history strategies in host-parasitoid systems [PDF]
, 2012 Question: How does cannibalism in the host alter the evolution of a parasitoid’s oviposition strategy? Can differences in cannibalism risk between parasitized vs. healthy hosts alter the stage foraging of parasitoids?
