Two different vibratory signals in Rhodniusprolixus (Hemiptera: Reduviidae)

Stridulatory sound emission of Panstrongylus rufotuberculatus Champion, 1899, (Hemiptera: Reduviidae: Triatominae)

“…the stridulation may act as a mechanism for repelling potential predators (leston, 1957), defensive behaviour or recognition between sex, for example in R. prolixus can indicated female reject males or defensive. the meaning keeps a relationship with the intensity and frequency of stridulatory sound, and this with inter-ridge distances on stridulatory grooves (manrique & Schilman, 2000;Schilman et al, 2001). the present study is the first record of audible sound in Panstrongylus rufotuberculatus Champion, 1899. of the buildings at the study site, and was kept alive in the laboratory for several days.…”

“…it has been suggested that sound emission in insects plays a role in gender identification during copulation (Chapman, 1998). in the case of triatominae, it has been established that such emissions are part of the intraspecific communication mechanisms (Schofield, 1977); for example, females that are nonreceptive to T. infestans Klug, 1834 or R. prolixus Stal, 1859 use sound to reject males (manrique & lazzari, 1994;manrique & Schilman, 2000). the stridulation may act as a mechanism for repelling potential predators (leston, 1957), defensive behaviour or recognition between sex, for example in R. prolixus can indicated female reject males or defensive.…”

The sexual behaviour of Panstrongylus megistus (Hemiptera: Reduviidae): an experimental study

“…40% for T. infestans. Stridulation in triatomines has been considered by several authors, either as a sexually related behaviour or as a defense response (Moore 1961, Manrique & Lazzari 1994, Roces & Manrique 1996, Manrique & Schilman 2000, Schilman et al 2001). According to Manrique and Lazzari (1994), non-receptive T. infestans females stridulate spontaneously, in order to reject the male copulatory attempts.…”

“…According to Manrique and Lazzari (1994), non-receptive T. infestans females stridulate spontaneously, in order to reject the male copulatory attempts. Roces and Manrique (1996) and Manrique and Schilman (2000) studying the stridulation of T. infestans and R. prolixus respectively, suggested that the relevant signal is a substrate borne vibration. In addition, they found differences in the frequency and temporal pattern of the signals produced by the same individual in different contexts, i.e., rejecting a male or after mechanical disturbance.…”

Triatominae (Hemiptera: Reduviidae): Systematic questions and some others

“…This view of triatomine stridulation is indirectly supported by the fact that in Triatoma infestans (Klug) (Roces & Manrique 1996) (Fig. 2) and in Rhodnius prolixus Stål (Manrique & Schilman 2000), both sexes produce disturbance stridulations, and unreceptive females produce a different stridulation to repel unwanted male attention.…”
