REPRODUCTIVE BEHAVIOUR OF THE DECORATED CRICKET, GRYLLODES SUPPLICANS (ORTHOPTERA: GRYLLIDAE): CALLING SCHEDULES, SPATIAL DISTRIBUTION, AND MATING by
نویسنده
چکیده
Male crickets (Orthoptera: Gryllidae) compete for females through direct physical aggression (ALEXANDER, 1961; BURK, 1983; BOAKE, 1984; DIXON & CADE, 1986) and acoustic signalling behaviour (ALEXANDER, 1975; CADE, 1979a). Females respond phonotactically to the calling songs of conspecific males by walking or flying to them (WALKER, 1957; ZARETSKY, 1972; ULAGARAJ & WALKER, 1973; PAUL, 1976; POPOV & SHUVALOV, 1977; CADE, 1979a; FORREST, 1980; SAKALUK, 1982). Mating is accomplished when a male successfully transfers the sperm-containing ampulla or spermatophore, which remains outside the female's body following the mating (ALEXANDER & OTTE, 1967). Often, the female subsequently consumes the evacuated spermatophore (ALEXANDER & OTTEN, 1967; LOHER & RENCE, 1978; SAKALUK & CADE, 1980, 1983).

The Morphological and Behavioral Analysis of Geographically Separated Rammeihippus turcicus (Orthoptera: Acrididae: Gomphocerinae) Populations: Data Result in Taxonomical Conflict
Rammeihippus Woznessenskij, 1996 (Orthoptera: Acrididae: Gomphocerinae) is a genus represented by two species. Rammeihippus turcicus (Ramme, 1939) is the only known species of the genus from Anatolia. As for most of the Gomphocerinae species in Anatolia, all populations of the species are intermittently distributed at high altitudes. In this study, three populations of R. turcicus were studied ...
متن کاملReproductive endocrinology of Syngnathidae.
Few studies have examined the underlying hormonal mechanisms that mediate reproductive cyclicity, male pregnancy and reproductive behaviour in syngnathids. Progress in these areas has been hampered by the small size of most species in the family and a lack of validated techniques for assessing endocrine function. Research on a relatively small number of species has suggested that androgens are ...
متن کاملSpatial swarm segregation and reproductive isolation between the molecular forms of Anopheles gambiae
Anopheles gambiae, the major malaria vector in Africa, can be divided into two subgroups based on genetic and ecological criteria. These two subgroups, termed the M and S molecular forms, are believed to be incipient species. Although they display differences in the ecological niches they occupy in the field, they are often sympatric and readily hybridize in the laboratory to produce viable and...

PREMISE OF THE STUDY Plant mating systems and geographic range limits are conceptually linked by shared underlying drivers, including landscape-level heterogeneity in climate and in species' abundance. Studies of how geography and climate interact to affect plant traits that influence mating system and population dynamics can lend insight to ecological and evolutionary processes shaping ranges....
متن کاملAre sex ratio distorting endosymbionts responsible for mating system variation among dance flies (Diptera: Empidinae)?
Maternally inherited bacterial endosymbionts are common in many arthropod species. Some endosymbionts cause female-biased sex ratio distortion in their hosts that can result in profound changes to a host's mating behaviour and reproductive biology. Dance flies (Diptera: Empidinae) are well known for their unusual reproductive biology, including species with female-specific ornamentation and fem...
