20221219_zia_c218_045 December 19, 2022, Kobe, Japan: VIDEO AVAILABLE: CONTACT INFO@COVERMG.COM TO RECEIVE**..Scientists have discovered that male mason wasps use sharp spines on their aedeagus, an insect organ broadly equivalent to a mammal's penis, to sting predators..A study in Current Biology on December 19 shows that the wasps use sharp genital spines to attack and sting predatory tree frogs to avoid being swallowed..â??The genitalia of male animals have frequently been studied in terms of conspecific interactions between males and females but rarely in terms of prey-predator interactions,â? said lead author Shinji Sugiura of Kobe University, Japan. â??This study highlights the significance of male genitalia as an anti-predator defense and opens a new perspective for understanding the ecological role of male genitalia in animals.â?.Suguira and study co-author Misaki Tsujii made the discovery after an accident. Tsujii was studying the life history of the mason wasp, Anterhynchium gibbifrons, when she got stung..â??Surprisingly, the male â??stingâ?? caused a pricking pain,â? Sugiura said. â??Based on her experience and observations, I hypothesized that the male genitalia of A. gibbifrons function as an anti-predator defense.â?.Wasps and bees are, of course, well known to use venomous stings to defend themselves and their colonies against attackers. But, because they have evolved venomous stings from ovipositors, males lacking ovipositors were believed harmless. Feeling the pain of a male sting didnâ??t add up..To study further, the researchers placed male wasps with a potential tree frog predator. All of the frogs attacked the male wasps, but just over a third spit them back out. The researchers witnessed the wasps stinging the frogs with their genitalia while being attacked..When they gave tree frogs wasps that were no longer endowed with genitalia? They ate them right up..The findings show that the m (Credit Image: © Cover Images vi
