Mite damage provides refuges and affects preference and performance of a subsequent herbivorous moth
Damage by herbivores often modifies plant structure and physiology, which may change the behaviour performance of future herbivores. Here, we studied such interactions among major coconut pest, mite Aceria guerreronis (Acari: Eriophyidae), two minor pests, Steneotarsonemus concavuscutum Tarsonemidae) moth Atheloca bondari (Lepidoptera: Pyralidae).
