Take flight: predation risk induces wing polyphenism and dispersal in the aphid Myzus persicae

open access: yesPest 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.

Characterization of larval gut microbiota of two endoparasitoid wasps associated with their common host, Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae)

open access: yesMicrobiology Spectrum
Insect gut microbes play important roles in digestion, metabolism, development, and environmental adaptation. Parasitoid wasps are one of the most important biological control agents in pest control, while the gut microbial species compositions and the ...

Plant-mediated effects in the Brassicaceae on the performance and behaviour of parasitoids [PDF]

open access: yes, 2009
Direct and indirect plant defences are well studied, particularly in the Brassicaceae. Glucosinolates (GS) are secondary plant compounds characteristic in this plant family. They play an important role in defence against herbivores and pathogens.

The functional role of ants in no‐till cropping systems

open access: yesPest 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.

The first report of M918L (super‐kdr) and L932F voltage‐gated sodium channel mutations in the English grain aphid (Sitobion avenae)

open access: yesPest 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.

Right combination of host instar and parasitoid age optimizes mass production of Tamarixia lyciumi, the nymphal parasitoid of goji berry psyllid Bactericera gobica

open access: yesJournal of Agriculture and Food Research
Goji berries are widely renowned for their nutritional and medicinal properties and are typically sold as dried fruit for their long shelf-life. Tamarixia lyciumi Yang is a nymphal parasitoid of the psyllid Bactericera gobica Loginova, a destructive pest

Sublethal herbicide exposure alters cotton susceptibility to aphid infestation

open access: yesPest Management Science, EarlyView.
Sublethal herbicide exposure altered cotton susceptibility to aphids. Aphid severity was highest when applications occurred at early vegetative stages and declined as the crop matured. In glasshouse, herbicide effects were dose‐dependent. Abstract BACKGROUND Herbicides remain vital tools for weed control, yet their effects can extend beyond weeds to ...

Juvenilhormon-Esterase, ein Schlüsselenzym in Wirt-Parasitoid-Interaktionen [PDF]

open access: yes, 2008
Hymenopteran endoparasitoids that develop inside their lepidopteran host may exert a multitude of interactions with their host until they are able to emerge successfully from a developmentally arrested host that finally dies.
