Sensitivity of Irish Pyrenopeziza brassicae populations to methyl benzimidazole carbamate (MBC), quinone outside inhibitor (QoI) and succinate dehydrogenase inhibitor (SDHI) fungicides

Pest Management Science, EarlyView.
For three collections of Irish Pyrenopeziza brassicae populations fungicide sensitivity status to methyl benzimidazole carbamate (MBC), quinone outside inhibitor (QoI) and succinate dehydrogenase inhibitor (SDHI) fungicides was determined using sensitivity screening in vitro. Molecular mechanisms of insensitivity have been identified for MBC and QoI in

Combined effects of canola plant density and insecticide management strategies on flea beetle abundance, canola defoliation, and yield across the Canadian prairies

Pest Management Science, EarlyView.
Increasing canola plant density reduced flea beetle abundance per plant and increased yield, independent of region or insecticide use, highlighting its potential as a component of integrated pest management. Abstract The crucifer flea beetle, Phyllotreta cruciferae (Goeze), and the striped flea beetle, Phyllotreta striolata (Fabricius) (Coleoptera ...

Monitoring demographic rates to assess the status of a reintroduced swan population

Avian Conservation and Ecology
Information about demographic vital rates is useful for assessing the status of reintroduced species and potential barriers to growth. We used an integrated population model to estimate and assess demographic vital rates of a Trumpeter Swan ( Cygnus ...

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

Pest 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.
