“…Male tettigoniids produce a proclamation song that attracts females (Morris et al, 1978;Bailey and Stephen, 1984;Bailey, 1985) and plays a role in intraspecific male competition (Morris, 1971;Meixner and Shaw, 1979;Latimer, 1981). Many bush cricket males continually sing for hours (see Meixner and Shaw, 1979;Schatral et al, 1985;Dadour and Bailey, 1985).…”

“…Males of the Australian bush cricket Mygalopsis marki (Thiele and Bailey, 1980;Dadour and Bailey, 1985) sing from the same plant for several days. However, in a few species males change their singing sites several times during one activity period (Meixner and Shaw, 1979;Shaw et al, 1981;Schatral et al, 1985). Schatral et al (1985) described the acoustic behaviour of the mobile bush cricket Decticus verrucivorus, and suggested that the conspecific song might affect locomotion in this species.…”

The bush cricket Psorodonotus illyricus is indigenous to the Balkans. Singing males of this species are highly mobile. The acoustic factors which might influence the locomotion were investigated in the field. The mobility of the males results in an often random distribution pattern. Interactions between the males are purely acoustic, and the duets are characterized by periods of good and poor alternation. Playback experiments, field observations and tape recordings of duetting males indicate that singing rate and sound intensity affect alternation behaviour and locomotion. However, the effect of the two song parameters is related to the time of the day, a phenomenon which might be due to (a) changes in the sound field around a singing male, and (b) altering microclimatic factors during the activity period of the insects.

“…The role of insect song as a mate locating system has been well established for many years. More recently attention has been directed to the relationship between song and spatial distribution and the role of acoustic behaviour in intraspecific male competition (MORRIS 1971(MORRIS ,1972ALEXANDER 1975;OTTE and JOERN 1975;CADE 1979;CAMPBELL and SHIPP 1979;MEIXNER and SHAW 1979;OTTE and LOFTUS-HILLS 1979;LATIMER 1980LATIMER , 1981. Acoustic inter-actions between males of certain species have been interpreted as being competitive in nature when aggressive behaviour is seen or when a leader or dominant insect can be identified by acoustic cues (JONES 1966;BUSNEL 1967;SHAW 1968;HEILIGENBERG 1969;YOUNG 1971;PHILIPPS and KONISHI 1973;OTTE and LOFTUS-HILLS 1979;LATl' MER 1981).…”

and Summary This study concerns the acoustic behaviour of the bush cricket Tettigonia cantans Fuess. (Orthoptera: Tettigoniidae). Natural habitats with different population densities of stable singers have been selected. The dispersion patterns of singing males and the sound levels neighbouring insects receive from each other were investigated. The behavioural patterns of an established male elicited by the song of a conspecific were analysed and related to the population densities of constant singers in their biotope. The competition between males and its possible effect on female behaviour have been discussed. Constantly singing males clump in areas with dense vegetation and within these clumps they are regularly spaced. Males seem to space themselves according to the song intensities (72–87 dB SPL) they receive from each other. Between close neighbours rivalry behaviour is expressed either by males producing alternating songs, or in an approach towards a constantly singing insect, or in an aggressive encounter. Of these three behaviour patterns aggressive encounters are most common in high‐density populations. Rivalry does not influence the dispersion pattern of the males. A hypothesis is inferred from observations on female behaviour that rivalry itself constitutes an attractive stimulus for females. Zusammenfassung Rivalenverhalten und Verteilung konstant singender Männchen der Laubheuschrecke Tettigonia cantans sind im Freiland untersucht worden. Dazu wurden unterschiedlich dichte Populationen gewählt. Konstant singende Männchen treten in Arealen mit dichter Vegetation gehäuft auf, sind aber innerhalb soldier Ansammlungen regelmäßig verteilt. Offenbar verteilen sich die Männchen nach gleichen Schalldruckpegeln (72–87 dB) im Gesang der Nachbarn. Das Rivalenverhalten kann in abwechselndem Singen eng benachbarter Männchen bestehen, in bloßer Annäherung an einen konstanten Sänger oder kann eine aggressive Begegnung einschließen. Besonders in dichten Populationen kennzeichnen agonistische Kontakte das Rivalenverhalten. Das Rivalenverhalten beeinträchtigt jedoch nicht das regelmäßige Verteilungsmuster der Männchen. Beobachtungen an Weibchen lassen vermuten, daß das Rivalenverhalten selbst einen stimulierenden Einfluß auf Phonotaxis und Auswahlverhalten der Weibchen ausübt.

Intra- and lnterspecific aggression in two species of field crickets,Gryllus integer andG. alogus

Adult, laboratory‐reared, and singly caged field crickets, Gryllus integer, of known ages and representing F1 to F4 generations, were exposed to 15–20‐minute bouts of social interaction with introduced adult intruder males on alternate days from approximately 1 week after adult molt to time of death. A total of 3,523 paired‐male bouts for 116 male G. integer were recorded over a 2.5‐year study period. Adult males used as intruders were wild‐caught or laboratory reared G. integer, but for nine of the 116 experimental males, wild‐caught intruders of a closely related sympathetic species, G. alogus, were used for all or many of the bouts. Bouts between male G. integer and conspecific intruders were characterized by significantly elevated levels of aggression (t=6.04, P<0.001) compared with males exposed to heterospecific G. alogus intruders in interspecific interactions. Significant differences (p<0.005, chi‐squared test of independence) existed at four out of five levels in a hierarchy of agonistic behaviors. Most G. integer males exposed to both G. integer and G. alogus intruders showed significantly reduced aggression levels during the interspecific interactions (p<0.001, Mann‐Whitney U test). Conspecific G. integer dyads in the intraspecific interactions showed significantly stable dominant‐subordinate relationships over time. Confusion surrounding the use of the term aggression is described with reference to Arthropods in general and Orthopteran insects in particular, and some likely proximate and ultimate bases for reduced interspecific aggression in field crickets are discussed.
