Scientists analyse the DNA of hornets found in nests to help them target hotspots in spring.
To the best of our knowledge, Oriental hornets are the only animal in nature adapted to consuming alcohol as a metabolic fuel ...
If a 175 pound-man drank five one-liter handles of vodka in a day, he would die. But when a tiny Oriental hornet weighing half a gram consumes the equivalent amount of alcohol relative to its body siz ...
in the form of larvae and pupae, back to their nests for food. Researchers have also observed Asian hornets around flower patches, which drives away honeybees, bumblebees, and other pollinators.
Each strike took just an instant, the predators snatching bees out of the air and then flying away with their victims, which would be carved up later and fed to the hornets’ own ravenous larvae.
Placed in fields and near manmade structures, bucket traps have a small hole at the top where the hornets enter to eat the sugars but can’t find their way out. Since the larvae rely on protein ...
Asian hornet larvae, pupae and adults are taken from the nest for genetic analysis. On the day we visit, scientists cut open a large, rugby ball-shaped nest - 20in (50cm) tall and 15in (40cm ...
With pointed tweezers, the scientists extract hornet larvae and pupae for analysis, along with all adult hornets. "As part of genetic analysis, we want to extract samples from all life stages," Ms ...
