Male Roptrocerus xylophagorum (Ratzeburg) (Hymenoptera: Pteromalidae) exhibited courtship and mating behaviors including wing fanning, antennation, mounting, and copulation attempts when exposed to glass bulb decoys coated with a whole-body extract of females in hexane, acetone, or methanol. Activity of extract-treated decoys declined gradually over one week. Males responded much less strongly to freeze-killed female cadavers extracted with solvents than to unextracted cadavers; treatment of… Expand
Characterization of a Female-Produced Courtship Pheromone in the Parasitoid Nasonia vitripennis
TLDR
It is demonstrated that male arrestment and key behavioral elements of the courtship sequence are mediated by a female-derived contact sex pheromone, and that sex-specific cuticular hydrocarbons are the key signals mediating the male courtship behavior in N. vitripennis. Expand
A female-produced short-range sex pheromone in the egg parasitoid Trissolcus brochymenae
TLDR
The findings suggest that courtship behaviour in males of T. brochymenae is triggered by a short-range sex pheromone produced by females, and the age and the physiological condition of females (virgin/mated) influence phersomone release or production. Expand
Female-Released Sex Pheromones Mediating Courtship Behavior in Lysiphlebus testaceipes Males
TLDR
Ethological aspects and chemical communication at close-range between the sexes of Lysiphlebus testaceipes Cresson have been investigated through behavioral bioassays and chemical analysis, showing that males exhibit a behavior including 4 phases when exposed to virgin females: premount, mount, copulation, and post-copulation.

Courtship Pheromones in Parasitic Wasps: Comparison of Bioactive and Inactive Hydrocarbon Profiles by Multivariate Statistical Methods
TLDR
Evidence is presented that the sex pheromone of L. distinguendus is composed of a series of cuticular hydrocarbons that differentiate bioactive and bioinactive hydrocarbon profiles, and may be responsible for pheromonal activity of hydrocarbon fractions in L. discrimendus. Expand
Evidence of a female-produced sex pheromone in the european pear psylla, cacopsylla pyri
TLDR
Electroantennogram recordings showed that female cuticular extracts elicit dose-dependent responses in male antennae suggesting the presence of volatile compounds capable to stimulate the male peripheral olfactory system. Expand
Chemical Ecology of the Parasitoid Wasp Genus Nasonia (Hymenoptera, Pteromalidae)
The use of chemical cues and signals is essential for communication in insects. Wasps of the genus Nasonia (Hymenoptera, Pteromalidae) are gregarious parasitoids that lay their eggs into puparia ofExpand
Cuticular Hydrocarbons as Contact Sex Pheromone in the Parasitoid Wasp Urolepis rufipes
TLDR
It is concluded that female-derived CHCs function as a contact sex pheromone in U. rufipes and that methyl-branched and n-alkanes act synergistically and that the sex-specific relative composition of the whole profile, rather than the abundances of single components, underlies the elicitation of male courtship behavior. Expand
Identification of an Important Component of the Contact Sex Pheromone of Callidiellum rufipenne (Coleoptera: Cerambycidae)
TLDR
Findings suggest that contact pheromones mediate mate recognition in this species, and 5,17-Dimethylnonacosane was a key sex-specific component in extracts of females, and synthetic 5, 17-dimethylnonACosane elicited a strong mating response from males. Expand
Response of Pteromalus cerealellae to conspecific odor: Evidence for female- and male-produced pheromones?
TLDR
Findings provide preliminary evidence for possible existence of a female-produced sex pheromone and close range cuticular chemicals by both sexes of P. cerealellae, which may play a role in courtship and species recognition. Expand
Cuticular hydrocarbons as contact sex pheromone in the parasitoid Dibrachys cavus
TLDR
Chemical analyses of bioactive and non‐active CHC profiles by gas chromatography–mass spectrometry and subsequent principal component analysis (PCA) revealed that the bioactive profiles from 1‐ to 2‐day‐old females were clearly distinguishable from all other profiles, and the putative function of 3‐methylalkanes as key components of the contact sex pheromones in Pteromalidae is discussed.

Evidence for a Substrate-Borne Sex Pheromone in the Parasitoid Wasp Trichogramma brassicae
TLDR
Substrate-borne pheromones may increase mating chances for virgin females searching for oviposition sites, and may also increase mating chance on emergence sites by reducing male dispersion. Expand
Courtship Behavior and Evidence for a Sex Pheromone in the Parasitoid Campoletis sonorensis (Hymenoptera: Ichneumonidae)
TLDR
Orientation and attempted copulation with males occurred as readily as with females in the presence of the female pheromone, and Ethyl acetate extracts of females were active in eliciting the courtship behavior of males. Expand
Courtship Behavior and Source of a Sexual Pheromone from Cardiochiles nigriceps
TLDR
Through amputation, ligation, and masceration of various parts of the female, sexual activity was revealed to be elicited by the female abdominal region, and Dufour's gland and hexane extracts of females elicited antennation by males. Expand
Multicomponent sex pheromone inMacrocentrus grandii Goidanich (Hymenoptera: Braconidae)
TLDR
A multicomponent sex pheromone inMacrocentms grandii Goidanich (Hymenoptera: Braconidae) was demonstrated using wind-tunnel and field bioassays and found to synergize strongly the hexane fraction. Expand
Evidence for a multicomponent sex pheromone inEriborus terebrans (Gravenhorst) (HYM.: Ichneumonidae), a larval parasitoid of the European corn borer
TLDR
Sex pheromone activity of Eriborus terebrans (Gravenhorst) was recovered from acetone rinses of flasks that previously contained females, and Chromatography data and chemical derivatization indicated that the polar component had the properties of a carboxylic acid with an additional oxygen-containing functional group.

Source of sex pheromone of the egg-larval parasitoid,Ascogaster reticulatus Watanabe (Hymenoptera: Braconidae)
TLDR
A sex pheromone of Ascogaster reticulatus Watanabe (Hymenoptera: Braconidae), identified as (Z)-9-hexadecenal, elicits males' antennal matesearching behavior and the presence of a tibial sex phersomone gland was suggested. Expand
BEHAVIOUR OF MALES IN RELATION TO THE FEMALE SEX PHEROMONE IN THE PARASITOID WASP, ANISOPTEROMALUS CALANDRAE (HYMENOPTERA: PTEROMALIDAE)
TLDR
Male sexual behaviour in Anisopteromalus calandrae was observed and experimentally analyzed and it was found that the male is attracted most effectively by the female still under the reed of the beans, which is essential for the recognition by males of the nearby presence of a female. Expand
Attraction of the Bark Beetle Parasitoid Roptrocerus xylophagorum (Hymenoptera: Pteromalidae) to Host-Associated Olfactory Cues
TLDR
The importance of the complete host/plant complex for attraction of R. xylophagorum to its host’s habitat is shown and a possible role for particular odors from uninfested host plant tissue in directing foraging parasitoids away from locations with few or no hosts is suggested. Expand
Alkadienes mediating courtship in the parasitoidCardiochiles nigriceps (Hymenoptera: Braconidae)
TLDR
Bioassays with three available alkadienes revealed that contact behaviors (antennation and mounting) are in part mediated by the (Z,Z)-7, 13-heptacosadiene and at least one other alkadiene in combination with other hydrocarbons found in males and females. Expand

TLDR
Males of the aphid hyperparasitoid Dendrocerus carpenteri (Curtis) were attracted by a sex pheromone released by conspecific females, and thus female attractiveness, depended both on the female's mating status and her age. Expand
