IPA: /ˌɔːtəʊˈiːʃəs/
KK: /ˈɔːtoʊˌiːʃəs/
Describing a type of organism that completes its entire life cycle on a single host without needing to switch to another host.
The plant species is autoecious, meaning it can grow and reproduce entirely on its own host plant.
Autoecious is formed from "auto-" (meaning self) and "oikos" (meaning house or habitat). The term describes organisms that complete their life cycle in a single host or environment, hence living in their own 'house.'
Think of 'self' ('auto-') living in its own 'house' ('oikos') — that's why autoecious refers to organisms that thrive in their own environment.
