BackgroundSexual selection is thought to promote evolutionary changes and diversification. However, the impact of sexual selection in relation to other selective forces is difficult to evaluate. Male digger wasps of the tribe Philanthini (Hymenoptera, Philanthinae) scent mark territories to attract receptive females. Consequently, the organs for production and storage of the marking secretion, the mandibular gland (MG) and the postpharyngeal gland (PPG), are subject to sexual selection. In… Expand
Comparative morphology of the antennal “release and spread structure” associated with sex pheromone-producing glands in male Cynipoidea
The observed conspicuous variability in RSS morphology seemed very weakly associated both with phylogenetic relationships among lineages and with life-history (galler, gall-associated inquilines or Parasitoids, and non-gall-associated parasitoids). Expand
Intra- and Interspecific Variation in Production of Bile Acids That Act as Sex Pheromones in Lampreys
It is postulate that bile acid production in males is shaped by directional or stabilizing selection that reduces variance within P. marinus and directional or disruptive selection that promotes diversification across species. Expand
Probable marking behavior of Cerceris clypeata (Philanthinae, Crabronidae, Hymenoptera)
The abdomen dragging behavior of C. clypeata and another member of the genus suggest that marking behavior is ancestral for the subfamily Cercerini, which includes Cerceris. Expand


The evolution of sexually selected traits in male swordtail fishes (Xiphophorus: Poeciliidae)
A reconstruction of the evolution of the sword-like caudal fin extension in males of species that belong to the genus Xiphophorus, and recent behavioural experiments suggest that female preference for mating with sworded males arose in ancestrally swordless species, is suggested. Expand
Morphology and ultrastructure of the allomone and sex-pheromone producing mandibular gland of the parasitoid wasp Leptopilina heterotoma (Hymenoptera: Figitidae).
The morphology and sizes of the mandibular glands of males and females of L. heterotoma have evolved to the multi-functional use of iridomyrmecin, which is used for chemical defense and as a major component of their sex pheromone to attract males. Expand
Male territoriality and mating system in the European beewolf Philanthus triangulum F. (Hymenoptera: Crabronidae): evidence for a “hotspot” lek polygyny
It is concluded that the European beewolf exhibits a hotspot lek polygyny with female nesting sites constituting “hotspots” for lek formation. Expand
Mating behavior and chemical communication in the order Hymenoptera.
It is shown that some orchids use hymenopteran sex pheromones to dupe males into performing pseudocopulation, with extreme species specificity, and many species appear to discriminate among mates at the level of individual or kin/colony, and they use antiaphrodisiacs. Expand
Brothers smell similar: variation in the sex pheromone of male European Beewolves Philanthus triangulum F. (Hymenoptera: Crabronidae) and its implications for inbreeding avoidance
One crucial prerequisite for females to be able to discriminate against brothers and avoid inbreeding is that the male sex pheromone varies with familial affiliation, and this hypothesis was tested by analysing the phersomone of male progeny of eight mothers using gas chromatography and mass spectrometry.

Comparative morphology of the postpharyngeal gland in the Philanthinae (Hymenoptera, Crabronidae) and the evolution of an antimicrobial brood protection mechanism
It is suggested that prey embalming has evolved as an antimicrobial strategy in and is restricted to the tribe Philanthini, which seems to face exceptional threats with regard to fungal infestations of their larval provisions. Expand
Male Sexual Signals and Female Choice in Drosophila grimshawi (Diptera: Drosophilidae)
Male mating success was found to be nonrandom and males that courted females intensely and deposited many pheromone-containing streaks on the substrate were the most successful, Hence, multiple cues seem to be involved in male mating success in this species. Expand
The evolution of sex pheromones in an ecologically diverse genus of flies
It appears that the mode of evolution of sex pheromones in Bactrocera is best described by rapid saltational changes associated with speciation, followed by gradual divergence thereafter, while species that do not overlap ecologically are just as different pheromonally asspecies that do. Expand
A moderately detailed account of the behavior of males of Eucerceris arenaria Scullen and Clypeadon taurulus Cockerell with emphasis on territoriality and activities that may serve to attract mates is provided. Expand
A Selfish Function of a “Social” Gland? A Postpharyngeal Gland Functions as a Sex Pheromone Reservoir in Males of the Solitary Wasp Philanthus triangulum
It is shown that in male beewolves, the PPG serves as a reservoir of the pheromone used to scent-mark their territories, and a dimorphism in the composition of the P PG contents is found, based on significant differences in the proportions of seven compounds between the two morphs. Expand
