Biobest’s latest research reveals the generalist aphid predator, Micromus angulatus, is active at temperatures as low as 12°C, so significantly earlier in the season than previously shown. This finding represents an important advance in early-season control of the large raspberry aphid (Amphorophora idaei), particularly in protected cropping systems.
“By enabling earlier biological intervention, this discovery supports a reduction in crop residues, labour-intensive spray applications, and associated environmental impacts,” explains Dr Liam Harvey, global technical specialist at Biobest. “It also has wider implications for improving aphid management in other crops early in the season.”
Persistent early-season threat
The large raspberry aphid is a key pest in raspberry production, feeding on new-season growth and excreting honeydew that promotes sooty mould development. Posing a serious threat to crop health and yield, it can also act as a vector for damaging plant viruses, spreading them within the crop.
