“…Moreover, aggressiveness may be different between the populations in their native environment versus in the invaded areas. Aggressiveness has been found to vary between individuals of V. vulgaris (Santoro et al 2015) and among V. germanica and V. vulgaris colonies in New Zealand (Jandt et al 2020). Jandt et al (2020) observed a consistent difference wasp colony aggression and suggested that both aggressive and nonaggressive behavioral types can have fitness benefits in a population.…”

Jandt et al (2020) observed a consistent difference wasp colony aggression and suggested that both aggressive and nonaggressive behavioral types can have fitness benefits in a population. If aggressive foundresses in the invaded area had a greater fitness or if more aggressive individuals were the ones that colonized the invaded area by chance, and if this behavioral trait is heritable, we may see differences in aggressiveness between populations in invaded versus native environments (Bengston and Jandt 2014).…”

Social wasps are important predators of honeybees, attacking hives to steal honey, pollen, larvae, and adults. Wasps of the genus Vespula are considered agricultural pests in many invaded areas, but their impact on Apis mellifera in these areas is poorly understood. Here, we studied agonistic interactions between V. germanica wasps and honeybees in Patagonia, Argentina. We found that the attack intensity was positively correlated with wasp density and that the colonies with lower honeybee traffic were the most affected by the wasps. We conclude that V. germanica has a significant impact on honeybees in this invaded area in Patagonia suggesting beekeepers need to be alert during the summer months to reduce wasp density of this insect pest.

“…Wasps are commonly perceived as more aggressive than bees, as they may, at least in theory, sting more than once. The "aggressive" behavior of worker wasps may also result from their hunting behavior, as wasps hunt animal protein for the meateating larvae, whereas bees are vegetarians (Sumner 2022; on variation in colony-level aggression, Jandt et al 2020). Interestingly, bee and wasp venom are used widely to relieve pain and treat inflammatory diseases such as rheumatoid arthritis (e.g., Pemberton 1999;Sumner 2022), so venom also has positive connotations.…”

Learning to live with unloved others is crucial in the ecological crisis. Unloved wasps are feared and disliked for their sting. Understanding of their ecological importance is increasing, however. Human-wasp encounters are changing with environmental changes, and strategies for multispecies cohabitation are needed. This multispecies study highlights features of wasp biology affecting human-wasp encounters and analyzes how conflicted human-wasp relations could be mitigated. The geographical focus is Finland, in the Northern boreal region. Biological analysis specified spatiotemporal aspects affecting human-wasp encounters: human and wasp habitats and preferences overlap ubiquitously. From a media analysis, we identified contextual strategies for living with wasps: exterminating, repelling, relocating, and giving space. Wasps do not receive only bad press – human-wasp relations are diverse and contextual. Knowledge of wasp ecology may allow for cultivating response-ability in multispecies encounters. Media provides information and narratives that allow reinterpreting wasp “aggression” as a vulnerable multispecies condition. Human-wasp encounters are corporeal and often preferably avoided. Therefore, methods that allow developing intimacy without proximity may be used for reflecting on human-wasp relations. One such method is crocheting decoy wasp nests. Human-wasp encounters could be mitigated by species-specific strategies that assess the risk involved. However, developing such strategies is difficult because wasps are often confused with other black-and-yellow insects.
