argylesock says… Don’t scare the bees! We need pollinators for crops and wild plants. There are many pollinating insects but one of those is the European honeybee (Apis mellifera). There are many kinds of hornet too, including the Asian hornet (Vespa velutina) which has become invasive in France, and which is expected to invade Britain soon. The post I reblog here is about experiments using Asian hornets and another kind of hornet to scare the Asian honeybee (Apis cerana). If our honebees behave like those Asian ones, they’re not going to like it when the hornets come. We might lose out on pollination.
In bees, fear is shown through avoiding dangerous food sites, thereby reducing the pollination of plants at the site. Scientists in this study looked at hornets (Vespa velutina and Vespa tropica) preying on the Asian honeybee (Apis cerana) in China. The hornets hunt bees on flowers and are themselves attacked by bees in defense. The study found that bees actively avoided feeders where predators were and decreased visitation to these risky sites. Bees treated the 4 fold more massive hornet species, Vespa tropica, as more dangerous, and these hornets received 4.6 fold more bee attackers than the smaller hornet species.
