As of May 23, 2016, the CLB model indicated that oviposition is well underway:
- In Alberta and western Saskatchewan, development was similar to the previous week.
- Warmer conditions in eastern Saskatchewan and Manitoba resulted in faster development.
- Larval populations are predicted to peak in mid-June across most locations in the southern prairies.
Predicted dates of peak emergence of CLB eggs and larvae:
The following model outputs have been updated this week and reflect the predicted stages of CLB present in fields in relation to its parasitoid, Tetrastichus julis.
Fact sheets for CLB are published by the province of Alberta and available from the Prairie Pest Monitoring Network. Also access the Oulema melanopus page from the new "Field crop and forage pests and their natural enemies in western Canada - Identification and management field guide".
