BACKGROUND
The pollen beetle (Brassicogethes aeneus) causes significant yield loss in oilseed rape (Brassica napus). Predicting population changes remains a scientific challenge, especially since its phenology and abundance varies dramatically over space and time. We used generalized additive models to investigate the long‐term trends in pollen beetle annual, seasonal and monthly counts from Rothamsted...
BACKGROUND
Agricultural landscapes provide resources for arthropod pests as well as their natural enemies. To develop integrated pest management (IPM) practices, it is important to understand how spatiotemporal location influences crop colonization and damage severity. We performed a 3‐year (2016–2018) field experiment in winter oilseed rape (OSR, Brassica napus) fields in Estonia, where half of...
