(3Z,6Z,8E)-3,6,8-dodecatrien-1-ol : Sex pheromone in a higher fungus-growing termite, Pseudacanthotermes spiniger (Isoptera, Macrotermitinae) Inra
Bordereau, C.; Robert, A.; Bonnard, O.; Le Quere, J.L..
The female sex pheromone of the fungus-growing termitePseudacanthotermes spiniger (Termitidae, Macrotermitinae) was isolated from sternal glands of alates. The compound inducing attraction and excitation in males was identified as the (3Z,6Z,8E)-3,6,8-dodecatrien-1-ol by GC-MS, microhydrogenation, GC-FTIR, and NMR. This unsaturated alcohol is present in both sexes but in much higher quantities in females than in males (about 10 times). The hypothesis is suggested that this alcohol, which is detected at extremely low concentrations by the workers ofP. spiniger, may be used either as a trail-following pheromone or a sex pheromone according to concentrations and to target castes. The presence of this alcohol in Macrotermitinae reinforces the idea of a...

Dictyoptera (Blattodea, Isoptera), Orthoptera, Phasmatodea and Dermaptera Inra
Rasplus, J.Y.; Roques, A..
For convenience, we treat all “polyneopteran” orders together. Five orders of hemimetabolous “Polyneoptera” include species alien to Europe, namely Blattodea, Isoptera, Orthoptera, Phasmatodea and Dermaptera. A total of 37 species alien to Europe have been recorded. Th ese belong to 14 diff erent families. Most of these species show a detritivorous feeding regime (22 spp.), whereas 12 species are phytophagous and two are predators. Th e majority of species were fi rst observed between 1900 and 1975. Unlike other arthropod groups, the mean number of polyneopteran species newly recorded per year showed no acceleration since 1975. Th e alien “Polyneoptera” mostly originated from Central/ South America and Asia (10 species each, 27.0%), followed by Africa (7,...

Sesquiterpenes in the frontal gland secretions of nasute soldier termites from new guinea Inra
Everaerts, C.; Roisin, Y.; Le Quéré, J.L.; Bonnard, O.; Pasteels, J.M..
In five New Guinea Nasutitermes (N. gracilirostris, N. novarumhebridarum, N. torresi, N. triodiae, and an undescribed species N. sp.F), we have detected and identified 10 sesquiterpenes. Eight of these compounds (β)-elemene,β-caryophyllene,α-humulene,α-muurolene,γ-selinene,β-selinene, germacrene-A, and γ2-cadinene) were identified by GC and GC-MS (EI). Two uncommon sesquiterpenes, (5R*, 7R*, 10S*)-selina-4(14),11-diene and (5R*, 7R*, 10S*)-selina-3,11-diene, were identified by GC, GC-MS (EI, CI), GC-FTIR, and mono- and bidimensional NMR. Whereas in most species sesquiterpenes are present in low or trace amounts, inN. novarumhebridarum the sesquiterpenic fraction of soldier frontal gland secretion is equal to that of the monoterpenes.
