See the main factors considered when estimating the risk of Asian hornet presence or pressure.
Content
The Asian hornet risk aims to indicate whether conditions are favourable for presence or increasing pressure around the apiary.
- Proximity to known nests or sightings.
- Number of sightings in the region.
- Season of the year.
- Weather conditions.
- Characteristics of the apiary location.
- Recent evolution of available records.
- Known behaviour of the species throughout the annual cycle.
A high risk does not mean that an attack is underway. It means that increasing vigilance, observing hive entrances, and preparing measures appropriate to the season and situation may be advisable.
