9-Hydroxydec-trans-2-enoic acid, a pheromone stabilizing honeybee swarms National Institute of Agronomic Research
Butler, C.G.; Callow, R.K.; Chapman, J.R..
A colony of honeybees (Apis mellifera L.) deprived of its hive and combs behaves like a reproductive swarm and will cluster on any convenient support. When the queen is taken away from such an artificial swarm, the workers soon become restless and increasing numbers fly off until eventually the cluster breaks up altogether.

An Expressed Sequence Tag collection from the male antennae of the Noctuid moth Spodoptera littoralis: a resource for olfactory and pheromone detection research Inra
Legeai, F.; Malpel, S.; Montagné, N.; Monsempes, C.; Cousserans, F.; Merlin, C.; Francois, M.C.; Maibeche Coisne, M.; Gavory, F.; Poulain, J.; Jacquin Joly, E..
Background :Nocturnal insects such as moths are ideal models to study the molecular bases of olfaction that they use, among examples, for the detection of mating partners and host plants. Knowing how an odour generates a neuronal signal in insect antennae is crucial for understanding the physiological bases of olfaction, and also could lead to the identification of original targets for the development of olfactory-based control strategies against herbivorous moth pests. Here, we describe an Expressed Sequence Tag (EST) project to characterize the antennal transcriptome of the noctuid pest model, Spodoptera littoralis, and to identify candidate genes involved in odour/pheromone detection.Results :By targeting cDNAs from male antennae, we biased gene...

Attractant-mediated behaviour of mobile stages of Heterodera schachtii IRD
Clemens, C.D.; Aumann,J.; Spiegel, Y.; Wyss, U..
La réaction des juvéniles de deuxième stade (J2) d'#Heterodera schachtii$ aux exsudats radiculaires et des mâles aux phéromones produites par les femelles à des distances variées de la source d'attraction, est étudiée en analysant l'orientation des traces laissées à la surface de l'agar. Deux types de J2 ont été testés : des J2 stimulés - précédemment soumis à des exsudats radiculaires - et des non stimulés. Les longueurs des traces ont été quantifiées de façon à différencier les comportements de recherche orientés et non orientés. La quantification des mouvements dirigés vers le gradient, ou à l'opposé de celui-ci, conséquence de chaque mouvement de recul, permet de différencier les effets attractifs et répulsifs. Aucun effet répulsif n'a été observé en...

Captures de Lobesia botrana Den. & Schiff. ( Lepidoptera, Tortricidae) au piège sexuel en relation avec la dose en phéromone du diffuseur Inra
Roehrich, R.; Carles, J.P.; Dreuilhe, A.; Vonderheyden, F..
Plusieurs essais de piégeage sexuel de Lobesia botrana ont été effectués avec différentes doses de phéromone E7, Z9 DDA. Le classement d’efficacité a été variable et semble dépendre de plusieurs facteurs. Les fortes doses (10 mg) sont attractives à des distances plus grandes et sont favorisées par la situation des pièges au milieu de grandes surfaces de vigne. Des doses 100 à 1000 fois plus faibles (1 ou 10 μg) que celle utilisée pour l’avertissement améliorent le rendement des captures parmi les papillons attirés et se placent ainsi en tête lorsque les conditions locales sont moins favorables à l’action à grande distance.

Characterization of an antennal carboxylesterase from the pest moth Spodoptera littoralis degrading a host plant odorant Inra
Durand, N.; Carot-Sans, G.; Chertemps, T.; Bozzolan, F.; Party, V.; Renou, M.; Debernard, S.; Rosell, G.; Maïbèche-Coisne, M..
Background: Carboxyl/cholinesterases (CCEs) are highly diversified in insects. These enzymes have a broad range of proposed functions, in neuro/developmental processes, dietary detoxification, insecticide resistance or hormone/ pheromone degradation. As few functional data are available on purified or recombinant CCEs, the physiological role of most of these enzymes is unknown. Concerning their role in olfaction, only two CCEs able to metabolize sex pheromones have been functionally characterized in insects. These enzymes are only expressed in the male antennae, and secreted into the lumen of the pheromone-sensitive sensilla. CCEs able to hydrolyze other odorants than sex pheromones, such as plant volatiles, have not been identified. Methodology: In...

Cloning and expression pattern of a putative octopamine/tyramine receptor in antennae of the noctuid moth Mamestra brassicae Inra
Brigaud, I.; Grosmaître, X.; Francois, M.C.; Jacquin-Joly, E..
In insects, biogenic amines have been shown to play an important role in olfactory plasticity. In a first attempt to decipher the underlying molecular mechanisms, we report the molecular cloning and precise expression pattern of a newly identified octopamine/tyramine-receptor-encoding gene in the antennae of the noctuid moth Mamestra brassicae (MbraOAR/TAR). A full-length cDNA has been obtained through homology cloning in combination with rapid amplification of cDNA ends/polymerase chain reaction; the deduced protein exhibits high identities with previously identified octopamine/tyramine receptors in other moths. In situ hybridization within the antennae has revealed that MbraOAR/TAR is expressed at the bases of both pheromone-sensitive and non-sensitive...

Cloning of an octopamine/tyramine receptor and plasticity of its expression as a function of adult sexual maturation in the male moth Agrotis ipsilon Inra
Duportets, L.; Barrozo, R.B.; Bozzolan, F.; Gaertner, C.; Anton, S.; Gadenne, C.; Debernard, S..
In the male moth Agrotis ipsilon behavioural response and antennal lobe (AL) neuron sensitivity to the female-produced sex pheromone increase with age and juvenile hormone (JH) level. We recently showed that the neuromodulator, octopamine (OA), interacts with JH in this age-dependent olfactory plasticity. To further elucidate its role, we cloned a full cDNA encoding a protein that presents biochemical features essential to OA/tyramine receptor (AipsOAR/TAR) function. The AipsOAR/TAR transcript was detected predominantly in the antennae, the brain and, more specifically, in ALs where its expression level varied concomitantly with age. This expression plasticity indicates that AipsOAR/TAR might be involved in central processing of the pheromone signal during...

Computational model of the insect pheromone transduction cascade Inra
Gu, Y.; Lucas, P.; Rospars, J.P..
All sensory neurons transduce their natural stimulus, whether a molecule, a photon, or a mechanical force, in an electrical current flowing through their sensory membrane via similar molecular and ionic mechanisms. Olfactory receptor neurons (ORNs), whose stimuli are volatile molecules, are no exception, including one of the best known: the exquisitely sensitive ORNs of male moths that detect the sexual pheromone released by conspecific females. We provide a detailed computational model of the intracellular molecular mechanisms at work in this ORN type. We describe qualitatively and quantitatively how the initial event, the interaction of pheromone molecules with specialized receptors at the ORN surface, is amplified through a sequence of linked...

E-beta-Ocimene, a volatile brood pheromone involved in social regulation in the honey bee colony (Apis mellifera) Inra
Maisonnasse, A.; Lenoir, J.C.; Beslay, D.; Crauser, D.; Le Conte, Y..
Background: In honey bee colony, the brood is able to manipulate and chemically control the workers in order to sustaintheir own development. A brood ester pheromone produced primarily by old larvae (4 and 5 days old larvae) was firstidentified as acting as a contact pheromone with specific effects on nurses in the colony. More recently a new volatile broodpheromone has been identified: E-b-ocimene, which partially inhibits ovary development in workers.Methodology and Principal Finding: Our analysis of E-b-ocimene production revealed that young brood (newly hatched to3 days old) produce the highest quantity of E-b-ocimene relative to their body weight. By testing the potential action of thismolecule as a non-specific larval signal, due to its high...

Effect of kairomones from egg and female adult stages of Ostrinia nubilalis (Hübner)(Lepidoptera, Pyralidae) ou Trichogramma brassicae Bezdenko (Hymenoptera, Trichogrammatidae) female kinesis Inra
Frenoy, C.; Durier, C.; Hawlitzky, N..
Volatile chemicals emanating from the different developmental stages of Ostrinia nubilalis Hübner (Lepidoptera, Pyralidae) increase the mobility of Trichogramma brassicae Bezdenko (Hymenoptera, Trichogrammatidae) in a linear airflow olfactometer. In this paper, we have demonstrated that airborne chemicals from egg masses and virgin females during calling activity stimulate an intensive search behavior byTrichogramma females. On the other hand, emanations from mated females with extruded abdominal tips do not incite the parasitoid''s movement. For the moment we cannot elucidate, with these bioassays, the real role of these kairomones as attractants, guides, stimulants, or retainers.

Efficient olfactory coding in the pheromone receptor neuron of a moth Inra
Kostal, L.; Lansky, P.; Rospars, J.P..
Efficient coding is an overarching principle, well tested in visual and auditory neurobiology, which states that sensory neurons are adapted to the statistical characteristics of their natural stimulus - in brief, neurons best process those stimuli that occur most frequently. To assess its validity in olfaction, we examine the pheromone communication of moths, in which males locate their female mates by the pheromone they release. We determine the characteristics of the pheromone plume which are best detected by the male reception system. We show that they are in agreement with plume measurements in the field, so providing quantitative evidence that this system also obeys the efficient coding principle. Exploring the quantitative relationship between the...

Egg dispersion in codling moth : influence of egg extract and of its fatty acid constituents Inra
Thiéry, D.; Gabel, B.; Farkas, P.; Jarry, M..
Codling moth females (Cydia pomonella, Lepidoptera: Tortricidae) (CM) usually lay single eggs and have a tendency to disperse. In a first experiment we observed that single females exposed to 20 apples distribute their eggs regularly among apples, suggesting a dispersive oviposition behavior. In a dual-choice situation, isolated females avoided oviposition on areas of cardboard treated with a methylene dichloride egg extract at the dose of ca. 1.0 egg equivalent/cm². A strong avoidance was obtained in response to a 20-fold dose, which was accompanied by a significant reduction of total oviposition. Seven major compounds found by GC analyses in the methylene dichloride extract of 2 to 3-day-old eggs were saturated or unsaturated C14-C18 straight-chain fatty...

Identification of geraniol as the active component in the Nassanof pheromone of the honey bee National Institute of Agronomic Research
Boch, R.; Shearer, D.A..
Honey bees (Apis mellifera L.) attract each other by a variety of biological stimuli. The olfactory stimulus produced by the worker bees has received attention during a number of investigations ever since Sladen1 suggested that the attractant odour originated from a special organ discovered by Nassanoff in 1883. This scent organ is located on the anterior part of the seventh abdominal tergum of the worker bee.

Identification of iso-amyl acetate as an active component in the sting pheromone of the honey bee National Institute of Agronomic Research
Boch, R.; Shearer, D.A.; Stone, B.C..
The sting of the honey bee (Apis mellifera L.) carries volatile substances which incite bees to aggression. This was first demonstrated by Huber, who elicited attacks by the guard bees when he placed freshly excised stings or the odour of stings near the hive entrance. Free found that cotton balls containing stings were more frequently stung than control balls.

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...

Monitoring the regional spread of the invasive leafminer Cameraria ohridella Deschka and Dimic (Lepidoptera: Gracillariidae) by damage assessment and pheromone trapping Inra
Augustin, S.; Guichard, S.; Svatos, A.; Gilbert, M..
The leafminer Cameraria ohridella Deschka & Dimic is an invasive pest of horse chestnut, Aesculus hippocastanum L., trees that has spread rapidly across Europe over the past 19 yr. It was recently reported in the United Kingdom, Denmark, and the Ukraine, and this spread is expected to continue through the Scandinavian countries until the northern limit of the host tree distribution is reached. The presence of the species is generally reported first in the cities, either as consequence of human-related transportation or because of the higher number of host trees in these areas. As a consequence, detailed studies of the spread of this pest through rural areas have not yet been carried out. We have monitored the spread of the moth at the fringe of its...

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....
