SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

open access: yesPest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

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

open access: yesPest 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.

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

open access: yesPest Management Science, EarlyView.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

open access: yesPest Management Science, EarlyView.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Colonization and spatiotemporal distribution of bruchid pests in lentil and faba bean fields

open access: yesPest Management Science, EarlyView.
This study of 104 fields identifies Bruchus signaticornis in lentils and B. rufimanus in faba beans as the sole grain‐damaging species. Their uniform distribution within fields and the strong effect of regulatory factors on larvae and egg survival emphasize the need for species‐specific, phenology‐based and spatially informed integrated pest management
