Article
Full-text available
Traditional views of copulation and sperm transfer supposed that females are passive participants. Recent discoveries suggest, however, that females actively influence the chances that a copulation will result in fertilization of their eggs, and that they sometimes signal to males during copulation in order to elicit male responses. This paper conc...

Nephila clavipes golden orb-web spiders accumulate prey larders on their webs and search for them if they are removed from their web. Spiders that lose larger larders (i.e., spiders that lose larders consisting of more prey items) search for longer intervals, indicating that the spiders form memories of the size of the prey larders they have accumu...

A long-standing mystery in morphological evolution is why male genitalia tend to diverge more rapidly than other structures. One possible explanation of this trend is that male genitalia function as “internal courtship devices,” and are under sexual selection by cryptic female choice (CFC) to induce female responses that improve the male’s chances...

Full-text available
Orb-weaving spiders construct webs with adhesive silk but are not trapped by it. Previous studies have attributed this defense to an oily coating on their legs that protects against adhesion or, more recently, to behavioral avoidance of sticky lines. The old evidence is very weak, however, and the behavioral avoidance explanation is inadequate beca...
Article
Full-text available
Spiders are effectively blind with respect to the lines in their webs, and they commonly use exploratory leg movements to find lines, just as a blind man finds objects using a cane. Nevertheless, a mature female Leucauge mariana (Keyserling 1881), which spins a relatively open, sparsely-meshed hub and whose legs I and II hold widely-spaced radii ra...
Article
Full-text available
Complex genitalia occur in many arthropods and in some species extreme female morphologies lead to serious mechanical difficulties for males. Tephritid flies offer examples of such complex genitalia. Because of their economic importance and the extensive use of sterile male releases for tephritid control in Texas and Mexico, studies have been done...

The evolutionary effects of crowding on male courtship behavior were studied using wild and mass-reared medflies. Mass-reared strains had been raised under highly crowded conditions in mass-rearing facilities for approximately 75, 180, and 238 generations. Pre-mounting courtship was facultatively shortened in both wild and mass-reared males under c...

Full-text available
The Sterile Insect Technique (SIT) has been used successfully to control or eradicate fruit flies. The commonly observed inferiority of mass-reared males, compared with wild males, when they are paired with wild females, is apparently due to their inadequate courtship. Anastrepha ludens males produce two types of wing vibration during courtship and...
Article
Full-text available
Mating behavior in Centruroides margaritatus, as in other scorpion species, includes a series of rapid rocking or shaking movements of the male (“juddering”). It has been suggested that substrate vibrations are generated by juddering and that females respond to them by approaching the male, but its functional significance remains little studied. Fo...

Los resultados de estudios previos que muestran que al exponer machos criados en masa de la mosca mediterránea de la fruta Ceratitis capitata (Wiedemann) al aceite de la raíz del jengibre (“aromaterapia”) aumentó la probabilidad del apareamiento con hembras naturales fueron confirmados. El aumento en el éxito de los machos puede ser debido a las re...

A possible explanation for one of the most general trends in animal evolution - rapid divergent evolution of animal genitalia - is that male genitalia are used as courtship devices that influence cryptic female choice. But experimental demonstrations of stimulatory effects of male genitalia on female reproductive processes have generally been lacki...
Article
One of the most sweeping of all patterns in morphological evolution is that animal genitalia tend to diverge more rapidly than do other structures. Abundant indirect evidence supports the cryptic female choice (CFC) explanation of this pattern, which supposes that male genitalia often function to court females during copulation; but direct experime...

The frequent interruption of male courtship in highly crowded mass-rearing cages of Ceratitis capitata (Wiedemann) was correlated with changes in both male courtship and female acceptance criteria in a mass-reared Costa Rican strain, in accord with previous studies of other strains. Abbreviation of courtship behavior by mass-reared males was associ...
Article
Full-text available
If species-specific male genitalia are courtship devices under sexual selection by cryptic female choice, then species-specific aspects of the morphology and behaviour of male genitalia should often function to stimulate the female during copulation. The morphology and behaviour of the complex, species-specific male genitalia of the tsetse fly, Glo...

ommon than previously appreciated, but its functional significance remains little studied. Stridulation during copulation by the female of the spider Physocylus globosus (Taczanowski, 1873), documented here for the first time, is common and noncoercive, thus permitting simple tests regarding its possible function. Males squeezed females rhythmicall...

Full-text available
Sexual dimorphisms in four related species of tephritid flies were shown to be associated with differences in sexual behavior. In two species, Ceratitis capitata and C. catoirii, males and females approach closely head to head and apparently touch aristae, and the male buzzes his wings, probably fanning pheromone toward the female; the males were f...

Males of the mutant strains (blind, vestigal-winged) of the Mediterranean fruit fly (medfly), Ceratits capitata (Wiedmann) showed differences in behavior compared with control (mass-reared) males. Mutant males made fewer mating attempts and achieved fewer matings than control males. Vestigal-winged females copulated less frequently with both mutant...

Analyses of more than 300 videotaped courtships of wild and mass-reared medflies from Costa Rica showed that the tendency for male and female to align themselves facing directly toward each other increased, and that the distance between them decreased as courtship proceeded. More direct alignments and shorter distances between the flies at the mome...

Male Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) used their aristae to repeatedly tap the female, usually on her aristae, during the second stage of head rocking courtship. The male's antennae moved in an apparently exploratory manner earlier in head rocking. Reduced rates of copulation followed removal of male and female aristae, support...

Full-text available
Experimental removal of the sexually dimorphic supra-fronto-orbital bristles from male Ceratitis capitata lowered the chances that courting males would succeed in mounting females. Bristle removal did not affect male courtship behavior, and females often did not contact male bristles, so the male bristles probably function as visual display devices...

Hypotheses regarding the function of elaborate male genitalia were tested in a sample of insects and spiders by comparing their allometric values (slopes in log-log regressions on indicators of body size) with those of other body parts. Male genitalia consistently had lower slopes than other body parts. Perhaps as a consequence of this pattern, gen...

Marked individual Tengella radiata spiders showed low and variable rates of weight gain in the field in old lowland forest in Costa Rica. Calibration studies of weight gained on controlled diets in captivity and rates of metabolism allow extrapolation of field results to probable rates of predation in the field.

The tropical earwigs Paralabella dorsalis and Pseudomarava prominensis are polymorphic for wings in both sexes. An individual's chances of being winged are influenced by whether its parents were winged, by its own sex, and by its nymphal nutrition (at least in P. dorsalis). Wingless females of P. dorsalis lived longer, started ovipositing ealier, a...

Mature males of four species of pholcid spider, three Modisimus species and one of Blechroscelis, search out mature females and cohabit webs with them. Males apparently compete for females. Males are dominant, but frequently cede prey to the females; paired males of at least two species feed less than solitary males. The function of this chivalrous...
