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.

COLLECTING NOTES ON COLEOPTERA

The Canadian Entomologist, 1906
While collecting at Brownwood, Texas, in the latter part of May, 1904, I secured half a dozen three- and four-inch sections of a Mesquite tree, about three inches in diameter, that had been cleared from land the preceding fall. The sections were infested with Coleopterous larv♀, and were put into a breeding box to see what would develop.

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

Pest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...
