High hymenopteran parasitoid infestation rates in Czech populations of the Euphydryas aurinia butterfly inferred using a new molecular marker [PDF]

Journal of Hymenoptera Research
We 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.

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

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 ...

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

Leaf penetration by endophytic Metarhizium brunneum enables infection of Phthorimaea absoluta in tomato mines while inducing the crop defense system

Pest Management Science, EarlyView.
Spraying Metarhizium brunneum on tomato plants controls heterogeneous and upcoming Phthorimaea absoluta populations by infecting larvae within mines and priming plant induced systemic defences. Abstract BACKGROUND The endophytic entomopathogenic fungus Metarhizium brunneum Petch EAMa 01/58‐Su shows strong potential for managing Phthorimaea absoluta, a ...

Location of Host and Host Habitat by Fruit Fly Parasitoids

Insects, 2012
Augmentative releases of parasitoids may be a useful tool for the area-wide management of tephritid pests. The latter are parasitized by many wasp species, though only a few of them are relevant for augmentative biocontrol purposes.

Host‐associated chemical cues mediating host‐finding behaviour in the larval ectoparasitoid Cephalonomia tarsalis

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 ...

Association of a Global Invasive Pest Spodoptera frugiperda (Lepidoptera: Noctuidae) with Local Parasitoids: Prospects for a New Approach in Selecting Biological Control Agents

Insects
Spodopotera frugiperda is a worldwide invasive pest that has caused significant economic damage. According to the classical biological control approach, natural enemies that can control invasive pests come from the same area of origin as the pests that ...
