Phase Differences

Female field crickets use phonotaxis to locate males by their calling song. Male song production and female behavioural sensitivity form a pair of matched frequency filters, which in Gryllus bimaculatus are tuned to a frequency of about 4.7 kHz. Directional sensitivity is supported by an elaborate system of acoustic tracheae, which make the ears function as pressure difference receivers. As a result, phase differences between left and right sound inputs are transformed into vibration amplitude differences. Here we critically tested the hypothesis that acoustic properties of internal transmissions play a major role in tuning directional sensitivity to the calling song frequency, by measuring tympanal vibrations as a function of sound direction and frequency. Rather than sharp frequency tuning of directional sensitivity corresponding to the calling song, we found broad frequency tuning, with optima shifted to higher frequencies. These findings agree with predictions from a vector summation model for combining external and internal sounds. We show that the model provides robust directional sensitivity that is, however, broadly tuned with an optimum well above the calling song frequency. We therefore advocate that additional filtering, e.g. at a higher (neuronal) level, significantly contributes to frequency tuning of directional sensitivity.

How sexual traits are gained and lost in the wild remains an important question in evolutionary biology. Pacific field crickets ( Teleogryllus oceanicus ) in Hawaii provide an unprecedented opportunity to investigate the factors facilitating evolutionary loss of a sexual signal in real time. Natural selection from an acoustically orienting parasitoid fly drove rapid evolution of a novel, silent male morph. While silent (flatwing) males enjoy protection from the fly, they face difficulty attracting mates. We tested how offspring production varies in association with three male attributes affected by the spread of flatwing: wing morph (flatwing or normal-wing), age (flatwings should survive longer than singers) and exposure to calling song during rearing (wild populations with many flatwings lack ambient calling song). Per mating event, flatwings sired more offspring than singers and older males were mounted more quickly by females when presented with standard courtship song. Despite prior work showing that male age and acoustic experience influence sperm characteristics associated with fertilization, age and song exposure had no influence on male offspring production per mating. This represents the first evidence that the silent male morph possesses a reproductive advantage that may help compensate for precopulatory barriers to mate attraction.

Gryllus Integer

Nightly and hourly rates of attraction of flying field crickets, Gryllus integer, to conspecific calling song were studied in an arena placed in the natural habitat of the species in central Texas. Calling of male G. integer in the arena and tape-recorded broadcasts of conspecific song were the sources of cricket song that subsequently attracted flying crickets. Observations were conducted for 10 h from approximately 1.5–2 h past sunset to 3 h past sunrise for 97 nights in 1983 and 1985–1988, using calling males, and for 4 nights in 1988, using taped song. The number of crickets attracted each night varied greatly, significantly more females were attracted, the numbers of males and females attracted decreased near sunrise, and significantly more crickets entered the arena from 2 to 6 h than from 7 to 11 h past sunset. Results are discussed in the context of mating behavior and sexual selection in this and other species.

Field crickets are extensively used as a model organism to study female phonotactic walking behaviour, i.e. their attraction to the male calling song. Laboratory-based phonotaxis experiments generally rely on arena or trackball-based settings; however, no attention has been paid to the effect of substrate texture on the response. Here, we tested phonotaxis in female Gryllus bimaculatus , walking on trackballs machined from methyl-methacrylate foam with different cell sizes. Surface height variations of the trackballs, due to the cellular composition of the material, were measured with profilometry and characterized as smooth, medium or rough, with roughness amplitudes of 7.3, 16 and 180 µm. Female phonotaxis was best on a rough and medium trackball surface, a smooth surface resulted in a significant lower phonotactic response. Claws of the cricket foot were crucial for effective walking. Females insert their claws into the surface pores to allow mechanical interlocking with the substrate texture and a high degree of attachment, which cannot be established on smooth surfaces. These findings provide insight to the biomechanical basis of insect walking and may inform behavioural studies that the surface texture on which walking insects are tested is crucial for the resulting behavioural response.

Host Effects

The song of male field crickets, Gryllus integer (Orthoptera: Gryllidae), attracts flies, Euphasiopteryx ochracea (Diptera; Tachinidae). Flies deposit larvae on male crickets and the larvae burrow in and consume the host. Effects of fly parasitism on duration of calling in G. integer were studied. Male crickets were collected at street lights and placed in jars and were electrically monitored for calling song. Calling duration was measured for 7 nights. Fly larvae were then placed on males and calling duration was measured for an additional 7 nights. In two replicates, males called significantly less following parasitism, and average calling duration declined gradually before death. Other males which remained free of fly larvae showed no reduction in calling. Field-collected males which subsequently died from fly parasitism called significantly less than non-parasitized males. Acoustically orienting flies reduce the ability of parasitized males to attract females acoustically.

Temperature Time

The structure of the calling song of the Texas field cricket, Gryllus integer, was studied. Pulse rates, percentage of missed pulses within a trill, numbers of pulses per trill or trill lengths, and intertrill intervals were measured for males singing in the field and in the laboratory. All song parameters were variable and were distributed normally. Intertrill intervals were longer in the laboratory, but all other parameters were similar in laboratory and field populations. Pulse rates varied in a linear fashion with ambient temperature in the laboratory and field. The percentage of missed pulses in a trill decreased with increasing temperature in the field and in the laboratory; intertrill intervals varied inversely with temperature only in the field. In field populations, immediately before and after sunrise male songs had fewer pulses per trill and a greater frequency of missed pulses than songs produced for a few hours following sunset. Song structure did not vary with age, weight, or hind-wing dimorphism. Most song parameters were correlated with each other. The data are discussed in terms of female choice and attraction to male song, male competition by way of acoustical interaction, and underlying genetic variation in G. integer.
