DIEL PERIODICITY OF SONG TYPE IN AN AQUATIC INSECT (PALMACORIXA BUENOI: HETEROPTERA: CORIXIDAE)
Published online by Cambridge University Press: 31 May 2012
Extract
The existence of a diurnal cycle in the rate of production of acoustic signals by aquatic heteropterans has been observed by several workers (Leston 1955; Mitis 1936; Schaller 1951; Theiss 1983). These accounts all mention an increase in acoustic activity in early evening. Jansson (1968, 1973) determined that the single strongest component releasing acoustic behavior was light level in the genera Cenocorixa and Callicorixa and that different species of Cenocorixa had different maxima. The study reported here began as an examination of diel periodicity of song incidence in the corixid bug Palmacorixa buenoi but results were substantially different in kind from most other studies of this nature in the literature.
