  • The Efficiency of Sound Production in Two Cricket Species, Gryllotalpa Australis and Teleogryllus Commodus (Orthoptera: Grylloidea)
    J. exp. Biol. 130, 107-119 (1987) 107 Printed in Great Britain © The Company of Biologists Limited 1987 THE EFFICIENCY OF SOUND PRODUCTION IN TWO CRICKET SPECIES, GRYLLOTALPA AUSTRALIS AND TELEOGRYLLUS COMMODUS (ORTHOPTERA: GRYLLOIDEA) BY MARK W. KAVANAGH Department of Zoology, University of Melbourne, Parkville, Victoria, 3052, Australia Accepted 27 February 1987 SUMMARY 1. Males of Gryllotalpa australis (Erichson) (Gryllotalpidae) and Teleogryllus commodus (Walter) (Gryllidae) produced their calling songs while confined in respirometers. 2. G. australis males used oxygen during calling at a mean rate of 4-637 ml O2h^', equivalent to 27-65mW of metabolic energy, which was 13 times higher than the resting metabolic rate. T. commodus males used oxygen during calling at a rate of 0-728 ml O2h~', equivalent to 4-34mW, which was four times the resting metabolic rate. 3. The sound field during calling by males represents a sound power output of 0-27 mW for G. australis and l-51XlO~3mW for T. commodus. 4. The efficiency of sound production was 1-05% for males of G. australis and 0-05 % for males of T. commodus. Comparison with other insect species suggests that none is more than a few percent efficient in sound production. INTRODUCTION Many insect species produce stereotyped acoustic signals that are important in intraspecific communication. In most species that communicate by sound, the male's calling song, which seems to attract conspecific females, is the most obvious and the most important component of the repertoire. Production of the calling song will involve a cost to the producer in the form of an increased use of metabolic energy.

Predicting the outcome of infection with novel combinations of 14 virus and host remains a key challenge in virus research. Host evolutionary relatedness can explain 15 variation in transmission rates, virulence, and virus community composition between host species, 16 but there is much to learn about the potential for virus evolutionary relatedness to explain variation 17 in the ability of viruses to infect novel hosts. Here, we measure correlations in the outcomes of 18 infection across 45 Drosophilidae host species with four Cripavirus isolates that vary in their 19 evolutionary relatedness. We found positive correlations between every pair of viruses tested, with 20 the strength of correlation tending to decrease with greater evolutionary distance between viruses. 21 These results suggest that virus evolutionary relatedness can explain variation in the outcome of 22 host shifts and may be a useful proxy for determining the likelihood of novel virus emergence.

  • Immune Function Reflected in Calling Song Characteristics in a Natural
    ANIMAL BEHAVIOUR, 2005, 69, 1235–1241 doi:10.1016/j.anbehav.2004.09.011 Immune function reflected in calling song characteristics in a natural population of the cricket Teleogryllus commodus LEIGH W. SIMMONS*,MARLENEZUK† &JOHNT.ROTENBERRY† *Evolutionary Biology Research Group, School of Animal Biology (M092), The University of Western Australia yDepartment of Biology, University of California, Riverside (Received 9 February 2004; initial acceptance 30 March 2004; final acceptance 24 September 2004; published online 17 February 2005; MS. number: 7999R) Secondary sexual traits have been suggested to provide reliable signals of a male’s ability to resist infection by agents of disease. The immunocompetence handicap hypothesis provides a potential mechanism for reliable signalling in the form of a trade-off between expenditure on trait expression and expenditure on immunity. Thus, males resistant to disease can spend more resources on their sexual signals. Examination of calling song parameters in a natural population of the cricket Teleogryllus commodus revealed that males scoring higher on the third principal component for song had significantly lower ability to encapsulate a foreign object. This component of immune function was associated with syllables of longer duration in both the trill and chirp elements of the song. Males with longer syllables in their song had a lower encapsulation ability. Syllable duration is known to influence phonotaxis by female T. commodus. Although the effect was only weak, our data suggest that females may base their choice of mate on reliable information contained within the temporal properties of male calls. Our study thus demonstrates a connection between sexual signalling and immune function in a natural population of insects and lends support to the immunocompetence handicap hypothesis.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

  • Recognition of Courtship Song in the Field Cricket, Teleogryllus Oceanicus
    Anim. Behav., 1996, 51, 353–366 Recognition of courtship song in the field cricket, Teleogryllus oceanicus ROHINI BALAKRISHNAN & GERALD S. POLLACK Department of Biology, McGill University (Received 4 November 1994; initial acceptance 9 February 1995; final acceptance 9 June 1995; MS. number: 7146) Abstract. The courtship song of the cricket, Teleogryllus oceanicus plays an important role in inducing the female to mount the male, which is necessary for mating. The song consists of a short, amplitude-modulated chirp, followed by a long trill of constant intensity and high syllable rate. Using playback techniques, it was determined which physical parameters of courtship song are necessary and/or sufficient to evoke normal female mounting of muted, courting males. The higher harmonics of natural courtship song were neither necessary nor sufficient for the effectiveness of the song. The chirp component alone was sufficient to evoke normal levels of mounting, but the trill was only partially effective on its own. The conspicuous amplitude modulation of the chirp was not necessary to evoke normal responses. The results suggest that the high effectiveness of the chirp is due to its characteristic temporal pattern. As in other cricket species, the song repertoire of T. oceanicus also includes distinct calling and aggression songs, which contain chirps that are structurally similar to the courtship chirp. Both calling and aggression songs evoked normal mounting responses when played back in the context of courtship. ? 1996 The Association for the Study of Animal Behaviour Crickets use acoustic signals to communicate and courtship songs are recognized share common with each other. These signals take the form of or similar features.

The 14 evolutionary relationships between host species can explain variation in transmission rates, 15 virulence, and virus community composition between hosts, but the potential for different viruses to 16 interact with host species effects has yet to be established. Here, we measure correlations in viral 17 load of four Cripavirus isolates across experimental infections of 45 Drosophilidae host species. We 18 find positive correlations between every pair of viruses tested, suggesting that broadly susceptible 19 host clades could act as reservoirs and donors for certain types of viruses. Additionally, we find 20 evidence of genotype-by-genotype interactions between viruses and host species, highlighting the 21 importance of both host and virus traits in determining the outcome of virus host shifts.

  • Male Field Cricket Song Reflects Age, Allowing Females to Prefer Young
    Animal Behaviour xxx (2010) 1e11 Contents lists available at ScienceDirect Animal Behaviour journal homepage: www.elsevier.com/locate/anbehav Male field cricket song reflects age, allowing females to prefer young males L. Verburgt*, M. Ferreira, J.W.H. Ferguson Department of Zoology and Entomology and Centre for Environmental Studies, University of Pretoria article info Sexual selection often involves female preference for males of a certain age, and a body of theory predicts Article history: preference for old males. We measured a comprehensive set of traits from the acoustic sexual display of Received 10 June 2010 male field crickets, Gryllus bimaculatus, and found that nearly all song traits changed predictably as males Initial acceptance 20 July 2010 aged, involving a general slowing down of the wing movements during song production. Our female Final acceptance 9 September 2010 preference experiments indicated a strong and repeatable preference for the songs of young males, Available online xxx contradicting the existing literature, which argues that female crickets prefer older males on the basis of MS. number: 10-00417R changes in song carrier frequency. Rather, female preference for young male song was determined by its high energetic quality. We develop the ‘old flight muscle’ hypothesis, arguing that age-related degradation Keywords: of stridulatory muscle performance is likely to result in the observed changes with age. Secondary sexual calling song characters may be subject to oxidative somatic degradation suggesting that, when males provide only female preference sperm, females should prefer the sexual displays of young males. Our results support new modelling Gryllus bimaculatus senescence approaches and a growing body of empirical evidence suggesting that old males are not always preferred sexual selection by females.

Variation in song patterns of Antipodean Teleo­ gryllus species (Orthoptera; Gryllidae) and a proposed phenetic classification. Can, J. Zool. 48: 797-801. The stridulations of eight sample populations of Teleogryllus commodus servillei (Saussure) and T. oceanicus (Le Guillou) were recorded and analyzed. Sokal's "distance coefficient" formula was used to derive a phenetic classification of the populations. The analysis indicates the same relationships as were previously indicated, by Chen et al.
