Results from 2018 survey: How is giant willow aphid affecting you?

Earlier this year we conducted a survey to help us to quantify the effects that giant willow aphid is having on New Zealand’s beekeeping community. The results varied between regions and individual respondents, however overall it was clear that the giant willow aphid is indeed problematic for beekeepers and is costing the apiculture industry. The results have helped us to identify what practices are currently being used to manage the effects of giant willow aphid, evaluate the merit of biological control as a potential long term solution. Many thanks to those who participated.
