KW - Tegenaria atrica [Biochemistry / / Cuticular compound synthesis & AB - Qualitative and quantitative changes in synthesis/release of the cuticular products were observed in Tegenaria atrica adult females and their young. In this spider species, 75 different compounds were detected by GC in the female and 36-41 in the young. Then these compounds were identified by GC-MS as mainly acids, methylesters, n-alkanes and monomethylalkanes containing 17-39 carbon atoms. The transition from gregarious to solitary life is accompanied by changes in agonistic behavior and in the composition of cuticular compounds. During the gregarious period, very few qualitative changes were observed in the level of synthesis/release of cuticular products of the young. After dispersal of the young, one n-alkane (n-heneicosane) and two monomethylalkanes (3-methylpentacosane and 14 -+ 12 -+ 10-methyltriacontane) appeared, when in three other compounds proportional changes were observed. The adult females had many more compounds, one part being the same as the young with different proportions, another part being new compounds, essentially hydrocarbons.

KW - Tegenaria atrica [Cuticle / / Cuticular compounds & cannibalism by AB - The present investigation was designed to study the relationships between the reproductive state of Tegenaria atrica females and their agonistic behavior towards conspecific females. Our results show that the virgin females exhibit the lowest levels of agonistic behavior whereas they provoke the highest levels of cannibalism by the mated females. The virgin females can be clearly distinguished from the other females as regards synthesis/release of cuticular compounds: methylesters and hydrocarbons. Furthermore, the ovaries of these females have not yet started vitellogenesis and the haemolymphatic ecdysteroids levels are high. It appears that the variation of females cannibalism parallels ovarian development and could be related to changes in cuticular compounds. Our results show for the first time that changes in spiders sexual and parental behavior during the reproductive cycle are accompanied by characteristic modifications in cuticular compounds, ovarian development as well as haemolymphatic ecdysteroid levels.

KW - Tegenaria atrica [Lipids / / Contact sex recognition signals on female AB - Qualitative changes in lipid content and composition were examined on the web and cuticle of Tegenaria atrica females in relation to sexual receptivity. In this spider species, 78 different compounds were detected by gas chromatography in the cuticle extract and 50 in the web; 28 identical compounds were present both on the spider silk and the cuticle of the female. The components were long-chain aliphatic hydrocarbons, fatty acids, and esters. On the web, sexual receptivity was correlated with changes in eleven polar compounds. On the cuticle, sexual receptivity was correlated with changes in eight polar compounds and 26 hydrocarbons. Bioassays demonstrated that the methanol eluate of webs and females were involved in stimulating the sexual behavior of males. Qualitative and/or quantitative changes in hexadecanoic acid, octadecadienoic acid, octadecenoic acid, methyl palmitate, methyl octadecanoate, and n-tricosane could play a role in the contact sex signals from web and cuticle ofT. atrica.

Male behaviours were not very spectacular and the acts expressed did not show a particular sequential organization. In most cases, approaches of the male toward the female were only accompanied by vibrations of the abdomen. The fact that these vibrations or palpal drumming could be expressed by the male before contact with the female indicates the possibility of the presence of a female pheromone. The observations are discussed in terms of ethological barriers and, as there occurred some gradation in male and female behaviours, in terms of mate choice.

KW - Tegenaria pagana [Courtship / / Tactile signals KW - use & reproductive isolation significance] [Evolutionary isolation / / AB - The aim of this paper was to study behavioural factors which can intervene in the reproductive isolation of the two sympatric species Tegenaria domestica and Tegenaria pagana, which are very close in systematic and present few morphological differences. In particular, we studied the modalities of the expression of courtship behavior. The behaviours were observed and the vibratory signals were recorded and analysed. The results show that it is possible to easily differentiate the two species. Indeed, male "motifs" of T. domestica are relatively simple and discreet, while those of male of T. pagana are more complex, with many acts' units performed repetitively. Adult males of the two species were tested on conspecific or heterospecific webs in the presence or absence of an adult female. On conspecific web, male courtship (in both species) can be diplayed in the absence of the female. On heterospecific web, with or without a female, courships are scarce for the two species. However, female of T. domestica show a particular vibration of their first legs, which could facilitate the release of courtship even on the web of T. pagan. These results corroborate the importance of silk structures as a means of communication which can participate in specific sexual recognition and in courtship.
