A New Invasive Pest in Plums: Monitoring and Control of Eurytoma schreineri
Original language description
The plum seed wasp Eurytoma schreineri is an invasive pest recently detected in the Czech Republic, posing a growing threat to European plum production. The larvae develop inside plum stones, causing premature fruit drop and yield losses of up to 90%. This study aimed to develop practical monitoring and control methods suitable for integrated pest management (IPM). Field experiments tested the attractiveness of differently coloured sticky traps, while laboratory and orchard trials evaluated the efficacy of several insecticides permitted in IPM systems. Results showed that yellow sticky traps were the most attractive to adult wasps and can serve as an effective tool for detecting pest presence and timing control measures. Among the tested insecticides, spinosad showed the highest efficacy under both laboratory and field conditions, reducing fruit infestation from nearly 80% in untreated orchards to 22% in treated plots. The combination of yellow trap monitoring and targeted use of spinosad represents an effective and environmentally acceptable approach to reducing E. schreineri populations. These findings provide growers with new tools for early detection and sustainable control of this invasive pest in plum orchards.
