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...

Post-mating sexual abstinence in a male moth Inra
Barrozo, R.; Gadenne, C.; Anton, S..
In most animals, male copulation is dependent on the detection and processing of female-produced sex pheromones. In males, a refractory post-ejaculatory interval (PEI) follows copulation, allowing them to avoid direct remating until they have replenished their reproductive tracts. In the moth Agrotis ipsilon, newly mated males show a transient inhibition of behavioral and central nervous responses to sex pheromone. Using nonpheromonal (plant) odors, pheromones and their mixture, we now show that the observed lack of pheromone response originates from differential post-mating odor processing in the brain. Although mated males still respond to plant odors alone, their response to mixtures depends on the added pheromone concentration. Below a specific...

QTL analysis for leaf gas exchange in an apple progeny grown under atmospheric constraints Inra
Regnard, J.L.; Segura, V.; Merveille, N.; Durel, C.E.; Costes, E..
The capacity of the apple tree to tolerate temporary abiotic constraints was investigated through leaf responses to different vapor pressure deficits (VPD). A ‘Starkrimson’ x ‘Granny Smith’ F1 progeny of 125 full-sibs whip-grafted onto Pajam® 2 rootstocks and pot-cultivated was studied (three replicates). After two months, plants were transferred into a controlled environment chamber ensuring five increasing VPDs, from 0.7 to 2.7 kPa, other conditions remaining constant. Leaf stomatal conductance (gsw), net CO2 assimilation (An) and transpiration (E) rates were measured, and water use efficiency (WUE, An/E) computed. The leaf responses were analyzed through a linear model including genotype as random effect for each VPD level separately. Whatever the VPD,...

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...
