...Nicolas Durand; Paleo Aguilar; Elodie Demondion; Thomas Bourgeois; Françoise Bozzolan; Stéphane Debernard ABSTRACT In the moth Agrotis ipsilon , the behavioral response of males to the female-emitted sex pheromone increases throughout adult life and following a prior exposure to sex pheromone...

... characterisation of two Δ12-desaturases, Nvit_D12a and Nvit_D12b, from the parasitic wasp Nasonia vitripennis. We demonstrate that Nvit_D12a is expressed in the rectal vesicle of males where they produce a linoleic acid-derived sex pheromone to attract virgin females. 13 C-labelling experiments with Urolepis...

...José G. Crespo; Franz Goller; Neil J. Vickers SUMMARY An essential part of sexual reproduction typically involves the identification of an appropriate mating partner. Males of many moth species utilize the scent of sex pheromones to track and locate conspecific females. However, before males engage...

...Romina B. Barrozo; Christophe Gadenne; Sylvia Anton SUMMARY In the moth, Agrotis ipsilon , newly mated males cease to be attracted to the female-produced sex pheromone, preventing them from re-mating until the next night, by which time they would have refilled their reproductive glands...

...Romina B. Barrozo; David Jarriault; Xenia Simeone; Cyril Gaertner; Christophe Gadenne; Sylvia Anton SUMMARY In the male moth, Agrotis ipsilon , mating induces a transient inhibition of behavioural and central nervous responses to sex pheromone. Newly mated males are not attracted to sex pheromone...

... are unsuitable for reproduction. Here, we study a long-lived moth Caloptilia fraxinella (Ely) (Lepidoptera:Gracillariidae) that is reproductively inactive from eclosion in summer until the following spring. Male sex pheromone responsiveness is plastic and corresponds with female receptivity. Pheromone response...

... the role of the antennae. Virgin pairs of the parasitoid perform an intense and stereotyped antennal courtship, which leads to copulation. During antennation, the two male fourth antennomeres come into contact with the two apical female antennomeres, and thus the secretion produced by the sex pheromone...

... components of the sex pheromone. However, for enhanced species specificity, it has been suggested that release of sex pheromone might be restricted to a narrow time period within the diel cycle. Here, we determine the structure, ratios and release patterns of iridoid chemicals produced by a serious global...

... but no chemicals have been identified so far. Here we report the first identification of a male sex pheromone in parasitic Hymenoptera. In abdomens of male jewel wasps, Nasonia vitripennis Walker, we found a mixture of(4 R ,5 R )- and(4 R ,5 S )-5-hydroxy-4-decanolide (HDL), which was released intermittently...

...Fabrice Marcillac; Jean-François Ferveur SUMMARY Sex pheromones are chemical signals used for mate attraction and discrimination in many invertebrate species. These compounds are often complex mixtures with different components having different effects. We tested live Drosophila melanogaster...
