Herbivore-Induced Changes in Cotton Modulates Reproductive Behavior in the Moth Spodoptera littoralis

2017

Plants produce chemical defense compounds to resist herbivore attack either by repelling the herbivores or attracting natural enemies of the herbivores. We have previously shown that volatile compounds from cotton released in response to herbivory by conspecifics reduce oviposition in cotton leafworm moth Spodoptera littoralis. It remained, however, unclear whether herbivore-induced changes also affect moth pre-mating and mating behaviors. In this study we examined the effect of herbivore-induced changes in cotton on reproductive behaviors i.e., female calling, male attraction and investment, and mating behavior in S. littoralis. We found a reduction in the number of females calling i.e., f…

Reconstrucció del paisatge rural i urbà d'Almenara i La Llosa entre els segle XIII al XVI

2023

La tesi titulada «Reconstrucció del paisatge rural i urbà d'Almenara i La Llosa entre els segles XIII-XVI», aprofundeix en l'evolució del paisatge cultural d'ambdós municipis i l'estudi de la seua població. Amb la finalitat de valorar els béns culturals municipals d'aquest període i destacar-ne la rellevància i les funcions en el passat. Cosa que possibilita una millor acceptació en el manteniment i en el respecte d'aquests béns en la societat actual. El paisatge constitueix una realitat dinàmica, ja que és resultat de processos ambientals, socials i culturals que s'han succeït al llarg del temps en el territori. Aquests processos estan marcats per les maneres de vida, les polítiques, les a…

Implication du récepteur 5-HT4 cardiaque humain dans la fibrillation auriculaire : rôle d’auto-anticorps dirigés contre ce récepteur ?

2004

The human cardiac 5-HT4 receptor was cloned in 1997. It is functional only in atrial myocytes where it is positively coupled via Gs to the adenylate cyclase, activates the cAMP-dependent protein kinase (PKA) and in consequence phosphorylates a variety of intracellular proteins implicated in excitation-contraction coupling. A number of studies suggest a role for the 5-HT4 receptor in the maintenance or elongation of atrial fibrillation. It is now accepted that certain cardiac pathologies involve auto-immune processes. Antibodies directed against the second extracellular loop of a number of cardiac G-protein linked receptors have been found. The human cardiac 5-HT4 receptor could therefore al…

Hybridization, developmental stability, and functionality of morphological traits in the ground beetle Carabus solieri (Coleoptera, Carabidae).

2006

Correspondance.: stephane.garnier@u-bourgogne.fr; International audience; The assessment of developmental stability in hybrids can provide valuable information in the study of species formation because it allows an evaluation of the degree of incompatibility of genetic systems that control developmental processes. The present study assessed the impact of two hybridization events, assumed to have occurred at different times, on developmental instability in the ground beetle Carabus solieri . Developmental instability was estimated in 678 individuals from 27 populations from the fluctuating asymmetry (FA) levels of four morphological traits: the tibia length of middle and hind legs, which are…

Hydrophobin (HFBI): a potential fusion partner for one-step purification of recombinant proteins from insect cells

2008

Hydrophobins play an important role in binding and assembly of fungal surface structures as well as in medium-air interactions. These, hydrophobic properties provide interesting possibilities when purification of macromolecules is concerned. In aqueous micellar two-phase systems, based on surfactants, the water soluble hydrophobins are concentrated inside micellar structures and, thus, distributed to defined aqueous phases. This, one-step purification is attractive particularly when large-scale production of recombinant proteins is concerned. In the present study the hydrophobin HFBI of Trichoderma reesei was expressed as an N-terminal fusion with chicken avidin in baculovirus infected inse…

Recurrent domestication by Lepidoptera of genes from their parasites mediated by Bracoviruses

2015

Bracoviruses are symbiotic viruses associated with tens of thousands of species of parasitic wasps that develop within the body of lepidopteran hosts and that collectively parasitize caterpillars of virtually every lepidopteran species. Viral particles are produced in the wasp ovaries and injected into host larvae with the wasp eggs. Once in the host body, the viral DNA circles enclosed in the particles integrate into lepidopteran host cell DNA. Here we show that bracovirus DNA sequences have been inserted repeatedly into lepidopteran genomes, indicating this viral DNA can also enter germline cells. The original mode of Horizontal Gene Transfer (HGT) unveiled here is based on the integrativ…

Effects of menu structure and touch screen scrolling style on the variability of glance durations during in-vehicle visual search tasks.

2011

The effects of alternative navigation device display features on drivers' visual sampling efficiency while searching forpoints of interest were studied in two driving simulation experiments with 40 participants. Given that the number of display items was sufficient, display features that facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations. As predicted, compared with a grid-style menu, searching information in a list-style menu while driving led to smaller variance in durations of in-vehicle glances, in particular with nine item displays. Kinetic touch screen scrolling induced a greater number of very short in-v…
