Evidence for male-produced aggregation pheromone in american palm weevil, Rhynchophorus palmarum (L.) (Coleoptera : Curculionidae) Inra
Rochat, D.; Gonzalez V., A.; Mariau, D.; Villanueva G., A.; Zagatti, P..
Field trapping of the American palm weevil (APW),Rhynchophorus palmarum, showed that the combination of caged male APWs and palm stem was much more attractive to APWs of both sexes than palm stem alone. Caged female APWs did not enhance the attractiveness of the palm. Caged APWs without palm stem were not attractive. Virgin laboratory-bred males were highly attractive to APWs of both sexes in a two-choice pitfall olfactometer, whereas virgin laboratory-bred females were not. Adsorbenttrapped volatiles from virgin laboratory-bred males reproduced the effect of living males, giving evidence for a male-produced aggregation pheromone in this species. Wild-mated APWs of both sexes were as responsive to the aggregation pheromone as virgin laboratory-bred APWs....

Field response of maritime pine scale, Matsucoccus feytaudi Duc. (Homoptera: Margarodidae), to synthetic sex pheromone stereoisomers Inra
Jactel, H.; Menassieu, P.; Lettere, M.; Mori, K.; Einhorn, J..
The absolute configuration of the primary component of the maritime pine scale (Matsucoccus feytaudi) pheromone (i.e., (8E, 10E)-3,7,9-trimethyl-8,10-dodecadien-6-one) was determined as 3S,7R by field-trapping experiments using synthetic stereoisomers and according to previous NMR considerations. The 3R,7R isomer showed similar activity to 3S,7R, whereasM. feytaudi males responded very weakly to the two other candidates (3R,7S and 3S,7S). Further studies were conducted to optimize scale trapping for monitoring scale populations. Results of these studies showed that the trapping efficiency was related to pheromone dose, trap area, and wind speed but not to trap height.

Identification of pheromone synergists in american palm weevil, Rhynchophorus palmarum, and attraction of related dynamis borassi Inra
Rochat, D.; Nagnan-le Meillour, P.; Esteban-Duran, J.R.; Malosse, C.; Perthuis, B.; Morin, J.P.; Descoins, C..
Thirteen host-plant kairomone blends, including 28 compounds, were tested and showed moderate to high synergy with rhynchophorol. The blends plus rhynchophorol also attracted the related Dynamis borassi. Ethanol–ethyl acetate blends in various ratios showed moderate synergy. Two blends, including "characteristic coconut" odor molecules, were as efficient as sugarcane in synergizing rhynchophorol and field luring American Palm weevils (APWs). Preliminary olfactometer tests of natural host-plant volatiles demonstrated the role of fermentation in primary APW attraction. The synergists were chosen from a comparative study of the odors emitted by four plant materials attractive to the APW: sugarcane, coconut, Jacaratia digitata tree and Elaeis guineensis (Oil...

Male aggregation pheromone of date palm fruit stalk borer Oryctes elegans Inra
Rochat, D.; Mohammadpoor, K.; Malosse, C.; Avand-Faghih, A.; Lettere, M.; Beauhaire, J.; Morin, J.P.; Pezier, A.; Renou, M.; Abdollahi, G.A..
Laboratory and field investigations were carried out to characterize the chemical communication system of the date palm fruit stalk borer, Oryctes elegans, and to develop pheromone-based trapping in Eastern Iran. Adults of both sexes feeding on date palm pieces attracted conspecifics, whereas date palm alone was minimally attractive. Males were twice as attractive as females. More beetles were captured at the palm crown than at ground level. Odors from adults feeding on sugarcane were sampled and analyzed by gas chromatography and mass spectrometry. Whereas females did not emit sex specific volatiles, males emitted a blend of 4-methyloctanoic acid (1: major component) and ethyl 4–methyloctanoate (2), occasionally mixed with minor components:...

Variability in pheromone communication among different haplotype populations of Busseola fusca Inra
Felix, A.E.; Genestier, G.; Malosse, C.; Calatayud, P.-A.; Le Rü, B.; Silvain, J.-F.; Frerot, B..
The relationship between pheromone composition and mitochondrial haplotype clades was investigated by coupling DNA analyses with pheromone identification and male mate searching behavior among different geographic populations of Busseola fusca. The within-population variations in pheromone blend were as great as those observed between geographic populations, suggesting that the female sex pheromone blend was not the basis of reproductive isolation between the geographic clades. Furthermore, while data from wind tunnel experiments demonstrated that most of the tested males were sensitive to small variations in pheromone mixture, there was considerable within-population variability in the observed response. The study identified a new pheromone component,...
