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.

Target‐site mutations and phenotypic failure in Myzus persicae against pyrethroids and carbamates in central Europe

open access: yesPest Management Science, EarlyView.
Molecular screening of 140 field‐collected Myzus persicae aphids revealed target‐site mutations L1014F, M918L, M918T, and L932F in the sodium channel and S431F in Ace2. The M918L mutation was the primary driver of high pyrethroid (cypermethrin) resistance, while S431F served as a definitive marker for carbamate (pirimicarb) resistance.

Binding and toxicity of plant lectins to insects [PDF]

open access: yes, 2002
The toxicity of plant lectins to insects after oral ingestion was investigated by incorporating the proteins into insect diets. Bioassays carried out using an artificial diet system demonstrated that kidney bean (Phaseolus vulgaris) lectin (PHA) caused a
