“…They showed that the parasitoids selectively responded to the vibratory calls of female hosts over those from males, male-female duets or control vibrations (Laumann et al 2007). Furthermore, the parasitoids distinguished between (and preferred) the vibratory signals of female E. heros hosts over those from females of alternative-host (Piezodorus guildinii) and non-host (Chinavia impicticornis) species (Laumann et al 2011). Of course, multimodal signals that combine a conspicuous, longer range advertisement signal with a more informative but shorter range signal may be particularly effective at attracting receivers (e.g.…”

“…In a series of experiments, Laumann et al (2007Laumann et al ( , 2011 recently demonstrated that scelionid egg parasitoid wasps (Telenomus podisi) eavesdrop on the plant-restricted sexual vibratory signals of their preferred stink bug (Euschistus heros) hosts. They showed that the parasitoids selectively responded to the vibratory calls of female hosts over those from males, male-female duets or control vibrations (Laumann et al 2007).…”

Dangerous liaisons: the predation risks of receiving social signals

Individuals are at risk when communicating because conspicuous signals attract both conspecifics and eavesdropping predators. This predation cost of communicating has typically been attributed to signalling individuals because of their conspicuous role, and is a core concept within sexual selection and communication ecology. But, if predators are attracted to signals, then receivers, both intended or otherwise, may also find themselves at risk of predation. Here, we review the theoretical basis and empirical evidence that receiving also carries a risk of predation. We distinguish between the risks of receiving and responding to signals, and we argue that receivers of signals that are long lived, are highly predictable in time or place and/or cannot be received quickly are likely to be at greater risk of predation compared to receivers of signals without these properties. We review recent empirical evidence from a variety of taxa that supports the hypothesis that receivers (including heterospecific prey) are aware of these risks and that they modify their behaviour to balance the risks against the benefits of receiving under predation threat. We also discuss the wider implications of risky receiving for receiving and signalling behaviour in prey, as well as for the prey's predators.

“…More rarely, a singing species will have true duetting behaviour, defined as an interaction between the adult male and female that is ‘… marked by the predictable and stereotyped temporal association between initiating call and the reply’ (Bailey, , p. 157). Such heterosexual duetting has evolved more often and to a greater degree of complexity in insects that communicate vibrationally, presumably because a female's song is less likely to be noticed by predators and parasites when it is confined to the local substrate (Bennet‐Clark, Leroy & Tsacas, ; Henry, ; but see Laumann et al ., for a counterexample). However, even when both sexes participate in an obligatory vibrational or acoustical duet, the exchange is usually asymmetrical – males typically produce longer, more complex, and/or more intense signals than females (e.g.…”

Obligatory duetting behaviour in theChrysoperla carnea‐group of cryptic species (Neuroptera:Chrysopidae): its role in shaping evolutionary history

An unusual system of communication has evolved in green lacewings of the Chrysoperla carnea-group, triggering rapid proliferation of numerous cryptic species across all of the Northern Hemisphere and large portions of Africa. The system is based on sexually monomorphic, substrate-borne vibrational signals, produced by abdominal oscillation. These low-frequency signals are exchanged between courting individuals in a precise duetting format. The song of each of the more than 20 described species exhibits a unique acoustical phenotype that reproductively isolates the taxon from all other species with which it might come into contact. Here, we review what is known about duetting behaviour in the carnea-group, emphasizing the dominant role that duetting has played in the evolution, ecology, and speciation of the complex. Included are descriptions and discussions of song diversity and its impact on reproductive isolation among species, the genetic basis of interspecific song differences, partitioning of acoustic space among sympatric species, parallel song evolution in allopatric species pairs, and modes of speciation within the complex. We also emphasize the importance of correctly identifying by song all species of the carnea-group that are to be used either in experimental studies or programs of biological control, while acknowledging the continuing relevance of morphology to carnea-group systematics.

“…They respond to plant volatiles induced by feeding stink bugs (Colazza et al., ; Moraes et al., , ; Michereff et al., ), host sex and alarm pheromones (Mattiacci et al., ; Borges et al., ; Colazza et al., ; Conti et al., ; Laumann et al., ), and traces left by stink bugs on the substrate (footprints) (Borges et al., ). For physical stimuli it is known that these parasitoids also respond to substrate‐borne vibratory signals produced during the sexual communication of stink bugs (Laumann et al., , ). However, there is no information about the influence of colour during the host‐searching behaviour of Scelionidae.…”

Insect parasitoids use a variety of chemical and physical cues when foraging for hosts and food. Parasitoids can learn cues that lead them to the hosts, thus contributing to better foraging. One of the cues that influence host‐searching behaviour could be colour. In this study, we investigated the ability of females of the parasitoid wasps Telenomus podisi Ashmead and Trissolcus basalis Wollaston (both Hymenoptera: Scelionidae) to respond to colours and to associate the presence of hosts – eggs of Euschistus heros (Fabricius) (Hemiptera: Pentatomidae) – with coloured substrates after training (associative learning). Two sets of experiments were conducted: in one the innate preference for substrate colours was examined, in the other associative learning of substrate colour and host presence was tested in multiple‐choice and dual‐choice experiments. In the associative learning experiments, Te. podisi and Tr. basalis were trained to respond to differently coloured substrates containing hosts in two sessions of 2 h each, with 1‐h intervals. In multiple‐choice experiments, the wasps displayed innate preference for yellow substrates over green, brown, black, or white ones. Even after being trained on substrates of different colours, both parasitoids continued to show preference for yellow substrates. The response to the colours of substrates of both parasitoids was related with the orientation to the plant foliage during the search for hosts.
