Mating Sequence

Cricket mating behavior reflects different strategies developed by sexual selection throughout evolutionary time. To our knowledge, only one species of the Neotropical cricket Trigonidiinae had its mating behavior studied so far. Here we expand this knowledge by describing the mating behavior of Cranistus colliurides Stål, 1861, a cricket commonly found in bushes and grasses along open fields or the forest edge. Adult crickets were collected in the municipality of Capão do Leão, State of Rio Grande do Sul, Brazil. Trials were carried out in laboratory to characterize the mating sequence. We quantified elapsed time of each behavioral sequence and discussed its implications in the observed mating behavior. The males of C. colliurides attracted females by means of a continuous trill, and receptive female triggers the beginning of the courtship through antennation. During courtship, copulation and post-copulatory actions, males showed a complex communication system based on information send to female by substrate vibration and an elaborated repertoire composed by calling, courtship and post-copulatory song. The mating behavior here described reveals divergence between related species hitherto studied which give us clues to understand how the sexual selection shaped the complex behaviors exhibited by Trigonidiinae crickets presently.

AbstractCuticualar hydrocarbons play an important role in chemical communication in social insects, serving, among other things, as nestmate, gender, dominance and fertility recognition cues. In ants, however, very little is known about the precopulatory signals cuticular hydrocarbons carry. These signals may serve as affecting sex pheromones and aphrodisiacs or as reliable signals for idiosyncratic traits, which indirectly affect sexual selection. In this study, we examined, for the first time, in the Cataglyphis genus, sex-specific variability in cuticular hydrocarbons. We focused on a species that exhibits split sex-ratio and found significant quantitative differences between virgin queens and their potential mates. In an analyses of both absolute amounts and relative amounts, we found different compounds to be significantly displayed on gynes and drones, suggesting absolute and relative amounts may carry different signals influencing mating behavior and mate choice. We discuss the possible signals advertised by the non-polar fraction of these hydrocarbon profiles.

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.

Abstract Mating behavior and sexual selection in relation to morphometric traits in a polygamous beetle, Glenea cantor (F.) (Coleoptera: Cerambycidae), were investigated. Upon encounter, a male approached a female, mounted her, grasped her terminal abdomen with his hind tarsi, and attempted to mate. Successful mating lasted about 3.5 h. Although all traits measured in females and half of traits in males were significantly correlated with mating success, the primary selection on virgin females was the genital trait, the bursa copulatrix length, and that on males was the body length and hind tarsal length. Longer bursa copulatrix accommodated a larger ejaculate, suggesting that this female trait benefits the male that first mates with the female in terms of increasing ejaculate size to beat subsequent males in sperm competition. Under a female-biased sex ratio, more than 20% of matings failed within 20s after the male genitalia had been inserted into hers, suggesting that males assess genital features of the female before insemination and undertake cryptic male mate choice. Larger males were more capable of grasping females and achieving mating. During the premating struggle the male almost always used his hind tarsi to lift the female terminal abdomen to the position for his genitalia to insert, and as a result, males with longer hind tarsi achieved higher mating success.

Diverse Groups

Although Anomalochrysa maclachlani shares many aspects of its life history and reproductive behavior with other green lacewings, it is atypical in several respects. (i) The preoviposition period is long, and it remains constant at temperatures from 21 through 26.7 °C. (ii) Fertility, which was 100% at 23.4 °C or lower, drops to 16.6% at 26.7 °C. (iii) Females oviposit clusters of about 25 unstalked eggs every 1–7 days, (iv) Both sexes produce loud clicking sounds during courtship; clicking frequently occurs in duet and is associated with anterior-directed flicks of the wings, (v) Females and males may mate repeatedly within several hours. The unusual features of A. maclachlani's reproductive behavior suggest a mode of sexual selection different from that in other chrysopids. Its loud courtship songs and those of other Hawaiian insects (Drosophila, crickets, plant hoppers) represent striking cases of parallel evolution among diverse groups of endemic fauna.
