Saltbush-associated Asphondylia species (Diptera: Cecidomyiidae) in the Mediterranean Basin and their chalcidoid parasitoids (Hymenoptera: Chalcidoidea) [PDF]
, 2014 Numerous species of gall midges (Diptera: Cecidomyiidae) have been recorded from saltbush (Chenopodiaceae: Atriplex) around the world but only 11 of them belong to the large cecidomyiid genus Asphondylia. Of these, two species were de-scribed in the late

Take flight: predation risk induces wing polyphenism and dispersal in the aphid Myzus persicae
Pest Management Science, EarlyView.Predator risk above a critical density induces winged morphs in Myzus persicae, promoting dispersal and reducing predation compared with wingless aphids. This density‐dependent phenotypic plasticity enhances survival but may compromise biological control by facilitating aphid dispersal.

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.

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?

The functional role of ants in no‐till cropping systems
Pest Management Science, EarlyView.Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.

Host Searching by Egg Parasitoids: Exploitation of Host Chemical Cues
, 2010 Insect parasitoids are considered “keystone species” in many ecosystems in terms of biodiversity, ecological impact and economic importance (Vinson 1985, LaSalle and Gauld 1993, Hawkins et al. 1999).

Larval parasitism of the autumnal moth reduces feeding intensity on the mountain birch [PDF]
, 2013 Plants respond to grazing by herbivorous insects by emitting a range of volatile organic compounds, which attract parasitoids to their insect hosts. However, a positive outcome for the host plant is a necessary precondition for making the attraction ...

Pest Management Science, EarlyView.The study has identified mutations in the voltage gated sodium channel of the English grain aphid (Sitobion avenae) at M918 and L932, which have not been previously reported in this species. Abstract BACKGROUND The grain aphid, Sitobion avenae Fabricius (Hemiptera: Aphididae), is a vector of yellow dwarf viruses and an important pest of cereals.
