What term is used to describe the larval excrement, which appears as fine, granular dust mixed with silk near the feeding site?
Answer
Frass
Detecting infestation signs often involves looking for the waste products left by the feeding caterpillars. The specific term for the larval excrement is frass. When this fine, granular dust is observed mixed in with the silken threads that the larvae spin while moving or cocooning, it serves as definitive physical evidence that active feeding and development are taking place within stored goods or structural voids, such as cracks and corners where pupation occurs.
