Abstract: This paper deals with the stridulation and associated behaviour in 15 species of adults of longhorned beetles in cerambycinae and lamiinae. with the prothorax stridulating organs, male or female beetles emit alarm sounds to respond to the stimulus from natural enemies or other beetles of same species. The oscillograms of alarm sounds of 13 species of beetles are greatly different from each other. A. horsfieldi beetles produce scratching sounds by the movement of fore-wing. Their stridulating organs tend to degenerate. Associated with mating behaviour, male beetles produce various sounds according to species and the physiological functions of these sounds to females are ignorant.

Key words: Cerambycidae, Sound production, Stridulation
