| 實物特徵: | Euthyrhynchus floridanus (Linnaeus) (Hemiptera: Pentatomidae) is a neotropical species belonging to the family Pentatomidae with over 4 000 species described, and is distributed from Florida to Brazil. This study describes the sexual behavior and reported for the first time the production of substrate vibrations by males and females during copulatory behavior and mating. Courtship and copulatory behavior, as well as the diverse signals, were recorded with a phonographic cartridge connected to a video camera. Female vibrations were reproduced in the absence of females and the responses by males were recorded. At least three types of substrate vibrations were distinguished in males and one in females, and these signals were characterized by their low frequency, varying from 127 to 180Hz. The sounds of E. floridianus males were significantly different in frequency, duration and number of pulses, both in courtship and in copulation, for the purring and drumming sounds. The production of sounds in this species is associated principally with mechanical, stimulatory behavior during courtship and copulation. Patterns of behavior and their relation to substrate vibrations suggest that these signals are important for the males in the context of mate location and sexual selection. |
