Emploi du piegeage sexuel avec des attractifs de synthese pour l'etude de la repartition dans la region parisienne de trois especes de tordeuses des vergers Inra
Frerot, B.; Boniface, B.; Chambon, J.P.; Meritan, Y..
Une année de piégeage sexuel des mâles de 3 tordeuses de la pelure, Archips podana, Pandemis heparana et Adoxophes orana au moyen d’attractifs de synthèse nous a permis de préciser leur répartition et leur importance dans la région parisienne. A. orana a disparu de la région de Versailles et de la Beauce mais pullule au Nord de Paris. Par contre, P. heparana et A. podana sont capturés dans toutes les parcelles en quantités variables. Nous avons aussi montré que A. orana cohabite avec P. heparana dans un même biotope. La non-sélectivité de certains attractifs nous a permis de mettre en évidence la présence de ravageurs potentiels, Clepsis spectrana et Argyrotaenia pulchellana, devant faire l’objet d’une surveillance lors des prochaines années.

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...

Mating-induced transient inhibition of responses to sex pheromone in a male moth is not mediated by octopamine or serotonin Inra
Barrozo, R.; Jarriault, D.; Simeone, X.; Gaertner, C.; Gadenne, C.; Anton, S..
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, and the sensitivity of their antennal lobe (AL) neurons is lower than in virgin males. This rapid transient olfactory inhibition prevents them from re-mating unsuccessfully until they have refilled their sex glands. We hypothesized that this olfactory ‘switch off’ might be controlled by neuromodulators such as biogenic amines. To test our hypothesis, we studied the effects of octopamine (OA) and serotonin (5-hydroxytryptamine, 5-HT) on the coding properties of pheromone-sensitive AL neurons in virgin and newly mated males. We show that AL neuron sensitivity increased in...

Molecular basis of female-specific odorant responses in Bombyx mori Inra
Anderson, A.R.; Wanner, K.W.; Trowell, S.C.; Warr, C.G.; Jacquin-Joly, E.; Zagatti, P.; Robertson, H.; Newcomb, R.D..
Males and females of many moth species exhibit important differences in sexual behaviours. Much research in this field has focused on the male-specific behaviour, electrophysiology and molecular biology of sex pheromone reception. Female-specific behaviours have been less well studied although, like male-specific behaviours, they could provide opportunities for intervention and management of lepidopteran pests. Previously, we identified genes encoding putative odorant receptors (ORs) from the genome of the silkworm, Bombyx mori, some of which have higher levels of steady-state transcript in the antennae of adult females compared with males. We have identified the full-length cDNA sequences of some of these ORs and described a novel OR that is part of a...

Ordinary glomeruli in the antennal lobe of male and female tortricid moth Grapholita molesta (Busck) (Lepidoptera: Tortricidae) process sex pheromone and host-plant volatiles Inra
Varela, N.; Avilla, J.; Gemeno, C.; Anton, S..
Both sexes of Grapholita molesta, a key pest of stone fruits, are able to detect host-plant volatiles and the sex pheromone emitted by females, and to modify their behaviour accordingly. How olfactory information is processed in the central nervous system is unknown. Intracellular recordings and stainings were used to characterize antennal lobe (AL) neuron responses to single pheromone components, a behaviourally active blend of five peach volatiles and a pear-fruit ester. AL neurons with different response patterns responded to pheromone components and plant volatiles. In males more neurons responded specifically to the main pheromone component than in females, whereas neurons responding to all three pheromone components were more abundant in females....

Piegeage sexuel de la processionnaire du pin, Thaumetopoea pityocampa Schiff. (Lep. Notodontidae) par des attractifs de synthese. Premiers essais dans le Sud-Ouest de la France Inra
Einhorn, J.; Menassieu, P.; Michelot, D.; Riom, J..
Une phéromone sexuelle attractive, l’acétoxy-1 hexadécen -13 (Z) yne- 11, a été identifiée récemment chez la femelle vierge de Thaumetopoea pityocampa Schiff. Dans la présente étude, l’attractivité sur le terrain de ce composé est démontrée et comparée à celle de l’isomère E. Par ailleurs, des effets de dose, de hauteur et de bordure sont mis en évidence dans le but d’une optimisation du piégeage. Enfin, les premières comparaisons entre piégeage sexuel et piégeage lumineux sont réalisées sur plusieurs sites du réseau de surveillance par pièges lumineux du Sud-Ouest de la France

Plant terpenes affect intensity and temporal parameters of pheromone detection in a moth Inra
Party, V.; Hanot, C.; Said, I.; Rochat, D.; Renou, M..
In moths, the components of the female pheromone blend are detected in the male antennae by pheromone olfactory receptor neurons (Ph-ORNs) expressing narrowly tuned olfactory receptors. Responses to sex pheromones have generally been thought to be independent from the odorant background. However, interactions between pheromone components and plant volatiles have been reported at behavioral and detection levels. To document the mechanisms of such interactions, we analyzed Ph-ORN responses of Spodoptera littoralis to the main pheromone component, Z9E11-14:Ac, in the presence of 4 monoterpenes. To mimic natural contexts in which plant odors and pheromone emanate from different sources, the 2 stimuli were presented with different temporal patterns and from...

Quantitative analysis of sex-pheromone coding in the antennal lobe of the moth Agrotis ipsilon: a tool to study network plasticity Inra
Jarriault, D.; Gadenne, C.; Rospars, J.P.; Anton, S..
To find a mating partner, moths rely on pheromone communication. Released in very low amounts, female sex pheromones are used by males to identify and localize females. Depending on the physiological state (i.e. age, reproductive state), the olfactory system of the males of the noctuid moth Agrotis ipsilon is `switched on or off'. To understand the neural basis of this behavioural plasticity, we performed a detailed characterization of the qualitative, quantitative and temporal aspects of pheromone coding in the primary centre of integration of pheromonal information, the macroglomerular complex (MGC) of the antennal lobe. MGC neurons were intracellularly recorded and stained in sexually mature virgin males. When stimulating antennae of males with the...

Switching attraction to inhibition: mating-induced reversed role of sex pheromone in an insect Inra
Barrozo, R.; Gadenne, C.; Anton, S..
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 for a potential new ejaculate. The behavioural plasticity is accompanied by a decrease in neuron sensitivity within the primary olfactory centre, the antennal lobe (AL). However, it was not clear whether the lack of the sexually guided behaviour results from the absence of sex pheromone detection in the ALs, or if they ignore it in spite of detection, or if the sex pheromone itself inhibits attraction behaviour after mating. To test these hypotheses, we performed behavioural tests and intracellular recordings of AL neurons to...

Three-dimensional antennal lobe atlas of the oriental fruit moth, Cydia molesta (Busck) (Lepidoptera: Tortricidae): comparison of male and female glomerular organization Inra
Varela, N.; Couton, L.; Gemeno, C.; Avilla, J.; Rospars, J.P.; Anton, S..
The oriental fruit moth Cydia molesta is an important pest and the behavioural role of olfactory signals such as pheromones and plant volatiles have been studied extensively in both sexes. To understand odour processing further, however, detailed knowledge of the anatomy of the olfactory system is crucial. In the present study, an atlas of the antennal lobe (AL) is presented based on the three-dimensional reconstructions of both ALs of three male and three female brains by means of neuroanatomical and computational approaches. We identified 48-49 "ordinary" glomeruli and one large glomerulus situated at the entrance of the antennal nerve in males, and 49-52 "ordinary" glomeruli and one large glomerulus in the ventro-medial part of the AL in females....

Transformation of the sex pheromone signal in the noctuid moth agrotis ipsilon: From peripheral input to antennal lobe output Inra
Jarriault, D.; Gadenne, C.; Lucas, P.; Rospars, J.P.; Anton, S..
How information is transformed along synaptic processing stages is critically important to understand the neural basis of behavior in any sensory system. In moths, males rely on sex pheromone to find their mating partner. It is essential for a male to recognize the components present in a pheromone blend, their ratio, and the temporal pattern of the signal. To examine pheromone processing mechanisms at different levels of the olfactory pathway, we performed single-cell recordings of olfactory receptor neurons (ORNs) in the antenna and intracellular recordings of central neurons in the macroglomerular complex (MGC) of the antennal lobe of sexually mature Agrotis ipsilon male moths, using the same pheromone stimuli, stimulation protocol, and response...

Un attractif sexuel pour la tordeuse des bourgeons : Archips xylosteana L. (Lep. Tortricidae Tortricinae) Inra
Frerot, B.; Renou, M.; Gallois, M.; Descoins, C..
Lors d’essais de piégeage sur le terrain, des mélanges binaires de divers acétates de tétradécène synthétiques ont été éprouvés comme attractifs sexuels potentiels pour des tordeuses de vergers de pommiers. Les pièges appâtés avec des mélanges d’acétoxy-1 tétradécène-11Z (Z11 TDA) et d’acétoxy-1 tétradécène-11E (E11 TDA) ont capturé des mâles d’Archips xylosteana L. La formulation 92 : 8 de Z11 TDA/E11 TDA s’est révélée être la plus efficace. Ces deux composés déclenchent des réponses électroantennographiques (E.A.G.) d’amplitude élevée chez les mâles. L’analyse par chromatographie en phase gazeuse du contenu volatil des glandes à phéromone des femelles vierges sur plusieurs types de phases stationnaires a confirmé la présence de ces deux composés...
