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.

Novel tetronamides derived from mucobromic acid: synthesis, structural elucidation, DFT calculations and phytotoxic activity

open access: yesPest Management Science, EarlyView.
The acyclic mucobromic acid, activated by (1S)‐(+)‐10‐camphorsulfonic acid, afforded the chiral compound 1b, precursor for aza‐Michael addition/elimination on the butenolide yielding tetronamides 2b‐7b. Their relative SRSR configuration was confirmed by the spectrometric methods, DFT calculation and statistical methods.

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 ...

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.
