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.

Copulation occurred primarily during the day. Some females copulated with different mates more than once. Females did not copulate immediately after their final moult and exhibited unpredictable mating receptivity patterns. Most males remained in females' webs for less than 1 day and copulated within the day of the visit. Males did not adopt a mating tactic of staying with a juvenile female until she moulted and matured, searching instead for adult female potential mates.

KW - Reproduction KW - Reproductive behaviour KW - Reproductive system KW - role of copulatory KW - sperm precedence & copulatory KW - University campus AB - Some females of the funnel-web spider, Agelena limbata multiply mate. After copulation, males make a visible copulatory plug which covers the female's genital opening. I assessed the effect of copulatory plugs on the fertilization success of second males, by conducting double mating experiments, using fertile and sterilized males in sequence. When females copulated with only one fertile male, more than 90% of their eggs were fertilized. Some males deposited complete plugs and other incomplete plugs. The relative size of the males to females and absolute male size affected the completeness of plugs. Complete plugs prevented another male's insemination completely, but incomplete plugs allowed insemination by second males. In general, first males had higher fertilization success than second or later males, and copulatory plugs enhanced the first male's advantage.

KW - mating success relations] [Evolutionary adaptation / / ] [Japan / / KW - Palaearctic region KW - relations KW - Reproduction KW - Reproductive behaviour AB - Field observations on the relationship between male mating success and emergence timing in the funnel-web spider, Agelena limbata, were conducted. Agelena limbata is an annual species and adult males appear slightly earlier than adult females in July. As males deposit a copulatory plug at the female epigynum after copulation, copulation with virgin females is important to males. The number of copulations in males with virgin females, which strongly correlates with the longevity of males and the number of females that males courted, did not correlate with the emergence timing of males. Early emerged males and females were significantly larger in size than later ones, but the correlation coefficient between the emerged date and the cephalothorax width was not strong. Males that emerged earlier did not have any advantage in copulating with larger and more fecund females. Furthermore, virgin females first copulated on average 7.9 days after their final molt and the mortality rate of adult males increased after the final molt. These factors may favor the smaller degree of protandry in male emergence timing in A. limbata.

KW - mating & reproductive success KW - Palaearctic region KW - related to size] [Japan / / Kyushu KW - relationships] [Mating / / Male size & reproductive success KW - relationships] [Reproductive productivity / / Male reproductive success KW - Reproduction KW - Reproductive behaviour AB - Field observations and laboratory experiments were conducted to assess the relation between male size and reproductive success in the funnel-web spider, Agelena limbata Thorell (Agelenidae), in 2 years. In this species, the body size of males is similar to that of females. In the field, size assortative mating occurred in both years. In 1 year, partial correlation coefficient analysis indicates that male cephalothorax width is a beter predictor of the copulated female cephalothorax width than of the date of pairing. In laboratory experiments, females tended to reject courting males that were smaller in relative body size, and males that were larger in relative body size had greater copulation success. Consequently female rejection of smaller courting males has some contribution to size assortative mating. Since larger females deposited more numerous eggs in the field, larger males are expected to have a higher reproductive success.

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 - Textrix denticulata [Genitalia / / Copulatory AB - The functional morphology of the copulatory organs of Histopona torpida (C. L. Koch, 1834) and Textrix denticulata (Olivier, 1789), investigated by semi-thin serial sectioning after freezefixation of the animals in copula, is described. In H. torpida, the long embolus runs through a precisely defined course in the membraneous genital pouch of the female vulva. The patellar apophysis locks the pedipalp in the female epigastric furrow. In T. denticulata this is accomplished by the retrolateral tibial apophysis that gets hold at the female scape. In both species the conductor has a locking as well as a guiding function for the embolus. A comparison with previously investigated agelenids shows a surprising diversity in the function of the retrolateral tibial apophysis.

Hatching success was excellent under overwintering conditions of repeated freeze-thaw. The variance in mean egg wt was great but increased egg wt (egg yolk) did not improve hatching success. Dry wt and fecundity were highly variable in this population. Egg wt, egg and spiderling number are positively correlated with dry weight of the female parent.

KW - Coelotes terrestris [Feeding behaviour / / Maternal provisioning KW - Nutrition KW - Parental care KW - regulatory mechanism] [Care of young / / ]. KW - Reproduction KW - Reproductive behaviour AB - The funnel-web spider Coelotes terrestris (Agelenidae) displays extended maternal care, especially characterized by a progressive provisioning of the young during a four-eight week gregarious phase. As they grow up, the spiderlings are provided with a increasing amount of prey, which is captured on the web and carried by the mother into the silk tube that represents the nest. This paper is aimed to determine the mechanism that could regulate, throughout the gregarious phase, this food-supply activity. Eleven females were observed, at different times, from one week before egg-laying till one week after the progeny's dispersal. Females' feeding behaviour noticeably changed from the young's emergence onwards. In particular, the prey was less and less handled and the overall time during which the mother kept her prey for herself.sbd.Prey Handling Time (PHT).sbd.steadily decreased. Meanwhile, the spiderlings reacted more and more rapidly to the mother's prey catching and carrying, and they stimulated her more and more actively. The mother's prey-supply behaviour was experimentally shown to be modifiable withing a short delay. Separating the mother from her brood made her shift her "Prey Handling Time" from a few minutes to more than two hours (i.e. about the level of the pre-emergence PHT). Conversely, reuniting the mother with her brood lead to an equivalent decrease of the PHT. This phenomenon was obtained at four different periods during the gregarious phase. The present study shows that, in this invertebrates species, the maternal provisioning activity is essentially regulated by exogenous factors: i.e. stimulations (that qualitatively and quantitatively variate in the course of time) emanating from the developing progeny.

AB - Three different modes of maternal food supply have been reported in the subsocial agelenid species Coelotes terrestris: prey provisioning, consumption of the mother's body, and regurgitation of nutritive fluids. Although the first two modes are well documented, the latter is not fully assessed. By comparing-in the absence of any prey-the weight variations in spiderlings either left with their mothers or isolated, and by simultaneously comparing the weight variations of mothers, either isolated or left within the group of spiderlings, it was possible to see evidence of a significant and long-lasting food transfer from the mother to her progeny. This food transfer probably explains the high level of survivorship and reduction of cannibalism showed by broods left with their mothers. Close observation provided no direct evidence of mouth to mouth transfer. Rather, the food transfer appears to involve the production and emission of miniature eggs by the mother when in presence of spiderlings, a phenomenon which to date seems not to have been noted among spiders.

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.

The present study clarifies the conditions which underlie female tolerance towards the young. Females at various stages of the reproductive cycle were each confronted with a group of ten 3-week-old spiders for 24 hours. Nursing and post-dispersal females perfectly tolerated the young presented to them while pre-laying and incubating females, on the contrary, were rather hostile and killed a number of the young presented to them. The difference in the attitude of the two categories of females shows that tolerance towards the young, like the prey-supply activity, depends on its reproductive state.

KW - Reproduction KW - Reproductive behaviour KW - Social behaviour AB - In C. terrestris, we have shown that the reproductive state of the female exerts a major influence on its aptitude to tolerate the young and ensure maternal care. Thus, only pre-emergence females were found to be aggressive towards young homospecifics. The purpose of the present study is to show that female intolerance towards spiderlings during non-gregarious periods is not a manifestation of a predatory tendency. The experiments show: that C. terrestris females discriminate conspecific young from prey (i.e. cricket larvae) more of which they kill and ingest; that C. terrestris females also discriminate the young of their own species from alien ones; and that this discrimination is at least partially based on cuticular chemical stimuli during body contact. This information is relevant to the understanding of some aspects of social behaviour. VL - 39 SN - 0376-6357 UR - ://ZOOREC:ZOOR13400015023 N1 - ZOOR13400015023 ER -
