Discovery and characterisation of succinate dehydrogenase inhibitor resistance in Plenodomus biglobosus (phoma stem canker of oilseed rape)

open access: yesPest Management Science, EarlyView.
SDHI resistance is reported and characterised for the first time in the oilseed rape phoma stem canker pathogen Plenodomus biglobosus (Leptosphaeria biglobosa). We investigate cross‐resistance patterns, associated SDH target‐site mutations, possible fitness costs, and consider the implications for disease and resistance management.

In planta fluxapyroxad gradients from seed treatment differentially select fungicide‐sensitive and reduced‐sensitive genotypes of Pyrenophora teres f. maculata

open access: yesPest Management Science, EarlyView.
Spatial concentration gradients of seed‐applied fluxapyroxad within barley create heterogeneous exposure environments, driving differential suppression of succinate dehydrogenase inhibitor‐sensitive Pyrenophora teres f. maculata isolates and enrichment of reduced‐sensitive genotypes, thereby shaping within‐host fungicide resistance selection dynamics ...

Progress report on Johnsongrass control in orchards

open access: yesCalifornia Agriculture, 1967
Johnsongrass, Sorghum halepense, is the most serious perennial weed control problem in California orchards. This fast-growing, warm-season weed propagates prolifically from seed and underground rhizomes. The fleshy underground stems provide the necessary

RNA interference of the ecdysone receptor gene AgEcR in a wolfberry ‐ specialized strain of Aphis gossypii Glover affects its survival and fecundity and confers resistance in transgenic goji (Lycium barbarum L.)

open access: yesPest Management Science, EarlyView.
AgEcR, an ecdysone receptor from Aphis gossypii, is an RNA interference (RNAi) target. Artificial diet screening of five double ‐ stranded RNA fragments identified dsAgEcR2 targeting the D/E junction as the most potent. Transgenic goji expressing dsAgEcR2 caused molting defects and reduced fecundity, suppressing population growth and offering a ...

Assessment of insecticide use practices in licensed pest control operators in North Carolina

open access: yesPest Management Science, EarlyView.
A statewide survey of 105 licensed North Carolina pesticide operators found ants, mosquitoes, and aphids as top target pests, pyrethroids as the dominant insecticide class (68%), and limited resistance monitoring, establishing a baseline for future insecticide resistance management and outreach.

Comparison of nonchemical, organic and synthetic Varroa destructor control strategies in honey bee colonies: effects on parasite load, colony strength and health

open access: yesPest Management Science, EarlyView.
Combining intensive drone‐brood removal with brood interruption provided the most effective and consistent seasonal Varroa control. Abstract BACKGROUND Varroa destructor remains the most significant biotic threat to honey bee colonies, and increasing resistance to synthetic acaricides necessitates alternative control strategies.

Automatic insect identification, counting, and monitoring techniques: a review

open access: yesPest Management Science, EarlyView.
Automated insect monitoring increasingly integrates optical, acoustic, infrared, radar, electrostatic, and biosensing technologies with artificial intelligence. No single approach is universally optimal; reliable deployment depends on task‐specific validation, representative datasets, robustness under field conditions, energy autonomy, connectivity ...
