The invasive predators, thought to have come from continental Europe, were discovered nesting in September in Alresford and Brockenhurst.
A deadly Asian hornet invasion threatening British honeybees could be averted using tiny electronic trackers. They tested the technique in southern France and Jerseywhere populations of the invasive species are already well established. The hornets prey on honeybees, hovering like attack helicopters outside their hives and grabbing them on the wing.
In social insects, the activity rhythm of foragers and their action range determinate the activity of the colony. In vespids, which are mostly predators, the foraging range of workers determines their maximum predation pressure round the nest. One of these species, Vespa velutinaa recently invasive species introduced into Europe, exerts a strong predation on honeybees at the hive.
Hornets insects in the genus Vespa are the largest of the eusocial waspsand are similar in appearance to their close relatives yellowjackets. Some species can reach up to 5. They are distinguished from other vespine wasps by the relatively large top margin of the head and by the rounded segment of the abdomen just behind the waist. Worldwide, there are 22 recognized species of Vespa Most species only occur in the tropics of Asia, though the European hornet Vespa crabrois widely distributed throughout EuropeRussiaNorth America and Northeast Asia.
By Robert Schrader. The Asian giant hornet inhabits some of the best travel destinations in Asia, which is terrifying if you happen to suffer from apiphobia fear of bees. Even if bees don't scare you, you'll probably be re-thinking your position if you happen to look at a photo of what happens to human skin after Asian giant hornet stings!
In Southeast Asia the native honey bee species Apis cerana is often attacked by hornets Vespa velutinamainly in the period from April to November. During the co-evolution of these two species honey bees have developed several strategies to defend themselves such as learning the odors of hornets and releasing alarm components to inform other mates. However, so far little is known about whether and how honey bees modulate their olfactory learning in the presence of the hornet predator and alarm components of honey bee itself.

Japanese honeybees face a formidable foe in the Asian giant hornet, a fierce predator that can reach 40mm long or larger, but the bees have developed a novel defense mechanism: they create a "hot defensive bee ball," swarming around the hornet and literally cooking it. Now, a new study published Mar. The researchers, including Takeo Kubo of the University of Tokyo and Masato Ono of Tamagawa University, actually sampled honeybees as they were engaged in a hot defensive bee ball, plucking them off the ball at different time points to investigate the brain function behind this unique adaptive behavior. Using a novel marker gene to detect the neural activity evoked in the brains of the honeybees that form the bee ball, they found that neurons that make up the higher brain center are active while the bees are part of the hot ball.
