Impact of transgenerational host switch on gut bacterial assemblage in generalist pest, Spodoptera littoralis (Lepidoptera: Noctuidae) Open
Diet composition is vital in shaping gut microbial assemblage in many insects. Minimal knowledge is available about the influence of transgenerational diet transition on gut microbial community structure and function in polyphagous pests. …
Drosophila Free-flight Odour Tracking is Altered in a Sex-specific Manner by Preimaginal Sensory Exposure Open
In insects such as Drosophila melanogaster , flight guidance is based upon converging sensory information provided by several modalities including chemoperception. Drosophila flies are particularly attracted by complex odours combining vol…
What should a poor mother do? Influence of host plant quality on oviposition strategy and behavior in a polyphagous moth Open
To maximise fitness, individuals may apply different reproductive strategies. Such strategies could be phenotypically plastic and vary depending on the environment. For example, when resources are limited females often face a trade-off bet…

G. sinense and P. notoginseng Extracts Improve Healthspan of Aging Flies and Provide Protection in A Huntington Disease Model Open
In the last decades, the strong increase in the proportion of older people worldwide, and the increased prevalence of age associated degenerative diseases, have put a stronger focus on aging biology. In spite of important progresses in our…
Experimental Introgression To Evaluate the Impact of Sex Specific Traits on <i>Drosophila melanogaster</i> Incipient Speciation Open
Sex specific traits are involved in speciation but it is difficult to determine whether their variation initiates or reinforces sexual isolation. In some insects, speciation depends of the rapid change of expression in desaturase genes cod…
Experimental introgression to evaluate the impact of sex specific traits on <i>Drosophila melanogaster</i> incipient speciation Open
Sex specific traits are involved in speciation but it is difficult to determine whether their variation initiates or reinforces sexual isolation. In some insects, speciation depends of the rapid change of expression in desaturase genes cod…

The desaturase1 gene affects reproduction before, during and after copulation in <i>Drosophila melanogaster</i> Open
Desaturase1 (desat1) is one of the few genes known to be involved in the two complementary aspects of sensory communication — signal emission and signal reception — in Drosophila melanogaster. In particular, desat1 is necessary for the bio…
Gene Regulation and Species-Specific Evolution of Free Flight Odor Tracking in Drosophila Open
The flying ability of insects has coevolved with the development of organs necessary to take-off from the ground, generate, and modulate lift during flight in complex environments. Flight orientation to the appropriate food source and mati…
Free flight odor tracking in Drosophila: Effect of wing chemosensors, sex and pheromonal gene regulation Open
The evolution of powered flight in insects had major consequences for global biodiversity and involved the acquisition of adaptive processes allowing individuals to disperse to new ecological niches. Flies use both vision and olfactory inp…
