Notes on Meaning
The word "bọ rầy" has two primary meanings in Vietnamese: 1. It commonly refers to beetles like the May-bug. 2. In agricultural contexts, especially concerning rice cultivation, it is also used to refer to small, sucking pests like aphids or planthoppers, which cause significant damage by directly feeding on plants and transmitting viral diseases. The specific type is often indicated by an adjective, e.g., bọ rầy nâu (brown planthopper).
