Behavioral responses of Spodoptera littoralis males to sex pheromone components and virgin females in wind tunnel Inra
Quero, C.; Lucas, P.; Renou, M.; Guerrero, A..
The major component of the sex pheromone of female Spodoptera littoralis, (Z,E)-9,11-tetradecadienyl acetate (1), elicited all steps of the male behavioral sequence, i.e., wing fanning and taking flight, oriented upwind flight and arrival to the middle of the tunnel, close approach and contact with the source. The activity was equivalent to that elicited by virgin females. In the range of doses tested, the dosage of 1 had no significant effect on the number of source contacts. Male response was significantly affected by light intensity, being optimum at 3 lux. Activity of the minor components (Z)-9-tetradecenyl acetate (2), (E)-11-tetradecenyl acetate (3), tetradecyl acetate (4), (Z)-11-tetradecenyl acetate (5), and (Z,E)-9,12-tetradecadienyl acetate (6)...

Dynamical modeling of the moth pheromone-sensitive olfactory receptor neuron within its sensillar environment Inra
Gu, Y.; Rospars, J.P..
In insects, olfactory receptor neurons (ORNs), surrounded with auxiliary cells and protected by a cuticular wall, form small discrete sensory organs – the sensilla. The moth pheromone-sensitive sensillum is a well studied example of hair-like sensillum that is favorable to both experimental and modeling investigations. The model presented takes into account both the molecular processes of ORNs, i.e. the biochemical reactions and ionic currents giving rise to the receptor potential, and the cellular organization and compartmentalization of the organ represented by an electrical circuit. The number of isopotential compartments needed to describe the long dendrite bearing pheromone receptors was determined. The transduction parameters that must be modified...

Endemic microorganisms of a Drosophila simulans strain and their relationships with the non-mendelian transmission of a character. Inra
Comendador, M.A.; Plus, N.; Louis, C.; Lopez-Ferber, M..
La souche SimES de Drosophila simulans se caractérise par la présence d’individus de phénotype S [malformations et (ou) suppression de soies thoraciques, principalement des dorso-centrales et des scutellaires], avec une fréquence de 50 à 60 p. 100. Ce phénotype est transmis maternellement, rendant donc plausible a priori le rôle de micro-organismes dans son déterminisme. De fait, 2 micro-organismes pathogènes ont été trouvés dans la souche SimES, la microsporidie Nosema kingi et un Picornavirus, le virus C de la Drosophile. Dans les mouches débarrassées de ces 2 micro-organismes, le phénotype S se maintient avec les mêmes propriétés. Ces 2 agents ne jouent donc aucun rôle dans le déterminisme de ce phénomène. Cependant, certains résultats...
