Scientists analyse the DNA of hornets found in nests to help them target hotspots in spring.

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.

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 ...

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 ...
