noun
parasitoidism
Technical term in biology/ecology for a parasitic relationship where the parasite eventually kills its host, typically seen in certain wasps and flies. Not a common everyday word.
捕食寄生は、寄生バチなどでよく見られる現象だ。
Parasitoidism is a phenomenon often seen in parasitic wasps and the like.
寄生 (parasitism) is a broader term for living on or in a host, often without immediately killing it. 捕食寄生 specifically refers to parasitoidism where the host is eventually killed.
Compound of 捕食 (predation) and 寄生 (parasitism), literally 'predatory parasitism'. The term is a modern scientific coinage.
