We have found that giant hornets (Vespa mandarinia japonica) are killed in less than 10 min when they are trapped in a bee ball created by the Japanese honeybees Apis cerana japonica, but their death cannot be solely accounted for by the elevated temperature in the bee ball. In controlled experiments, hornets can survive for 10 min at the temperature up to 47°C, whereas the temperature inside the bee balls does not rise higher than 45.9°C. We have found here that the CO2 concentration inside… Expand
Differences in Heat Sensitivity between Japanese Honeybees and Hornets Under High Carbon Dioxide and Humidity Conditions Inside Bee Balls
TLDR
The lethal temperature of hornets exposed for 10 min to different humidity and CO2/O2 (oxygen) levels was determined and the four hornet species used in this experiment died at 44–46°C under these conditions. Expand
European honeybee defense against Japanese yellow hornet using heat generation by bee‐balling behavior
TLDR
The results suggest that European honeybees kill hornets by raising the body temperature of hornets rapidly without stinging, and the tactics of bee‐balling against hornets are complex and may be performed by extended division of labor. Expand
The Potential of Bee-Generated Carbon Dioxide for Control of Varroa Mite (Mesostigmata: Varroidae) in Indoor Overwintering Honey Bee (Hymenoptera: Apidae) Colonies
TLDR
It is suggested that restricted ventilation has potential to suppress varroa mite in overwintering honey bee colonies via a low-cost and environmentally friendly measure. Expand
Cooperative wasp-killing by mixed-species colonies of honeybees, Apis cerana and Apis mellifera
TLDR
The results suggest that the two species of honeybees can cooperate in joint heat-balling against the wasps, but A. cerana was more assertive in such defence. Expand
Characterizing thermal tolerance in the invasive yellow-legged hornet (Vespa velutina nigrithorax): The first step toward a green control method
TLDR
The most promising and potential technique for quickly destroying hornet nests may be steam injection, as the humid airflow system killed all hornets within 13 seconds, and therefore could be a good candidate for a green nest control method. Expand
Defence reactions of Apis mellifera ligustica against attacks from the European hornet Vespa crabro
TLDR
Comparing the differences and similarities of this behaviour with those observed in other species of Apis and Vespa reveals that these two species are an interesting model for the study of the evolutionary arms race. Expand
Lethality of Honey Bee Stings to Heavily Armored Hornets
TLDR
It is shown that bees can sting hornets but most hornets are able to remove bee stings less than 1 min after being stung, perhaps explaining why stinging is not considered a major anti-hornet defense, and that the combination of sting venom and being heated is the most lethal to hornets. Expand
Oriental Orchid (Cymbidium floribundum) Attracts the Japanese Honeybee (Apis cerana japonica) with a Mixture of 3-Hydroxyoctanoic Acid and 10-Hydroxy- (E)-2-Decenoic Acid
TLDR
The flower of the oriental orchid Cymbidium floribundum is known to attract the Japanese honeybee Apis cerana japonica and a mixture of 3-hydroxyoctanoic acid and 10-HDA was identified as the active principles from the orchid flower, which strongly supports the idea that orchid flowers mimic bee secretions. Expand
Double-edged heat: honeybee participation in a hot defensive bee ball reduces life expectancy with an increased likelihood of engaging in future defense
TLDR
It was found that the high temperature inside the ball itself dramatically reduced honeybee longevity, and bee ball-participating and then short-lived worker honeybees had a tendency to join a subsequent bee ball more aggressively. Expand
Risk assessment for the establishment of the Asian giant hornet (Vespa mandarinia) in the Pacific Northwest
TLDR
Many of the western counties of both Washington and Oregon were estimated to be at the highest risk of establishment mainly due to their suitable climate for queens to overwinter, dense forest biomass for nest colonization, and proximity to major port and freight hubs in the region. Expand

Heat production by balling in the Japanese honeybee,Apis cerana japonica as a defensive behavior against the hornet,Vespa simillima xanthoptera (Hymenoptera: Vespidae)
TLDR
As an effective counterattack strategy against predacious hornets, workers of Apis cerana japonica showed a distinct balling reaction, usually involving 180–300 bees, which produced heat for as long as 20 min, giving rise to temperatures higher than 46°C, which is lethal to the hornet but not to the bees.

Heat-balling wasps by honeybees
TLDR
Both species of honeybees have a thermal safety factor in heat-killing such wasp predators, and the results show remarkable thermal fine-tuning in a co-evolving predator–prey relationship. Expand
