To extract any adaptive benefit, the circadian clock needs to be synchronized to the 24-h day-night cycles. We have investigated if it is a general property of the brain’s circadian clock to recognize social interactions as external time givers. Sociosexual interactions with the opposite sex are universal, prevalent even in the lives of solitary animals. […]

Emmanuelle Jacquin-Joly was invited to give a talk at the agricultural ministers’ conference of date producing and processing countries around the world, organized in Adu Dhabi, United Arab Emirates, on February 26 and 27, 2024. Her presentation focused on the possibility of combating the red palm weevil through a better knowledge of its odorant receptors, and in particular its pheromone aggregation odorant receptor.

On October 24 and 25, the Ecosens department hosted the ADALEP (Adaptation of Lepidoptera) national network days on the INRAE Versailles-Saclay campus. Around two plenary conferences given by invited researchers from New Zealand (Invasomics Lab; Institute for Plant and Food Research). These days brought together more than twenty presentations on invasions, expansion fronts, adaptation and […]

A study in Biological Reviews led by researchers from the Institute of ecology and environmental sciences – Paris, the Institute of Systematics, Evolution, Biodiversity and the Center for Ecology and Conservation Sciences makes the synthesis of published knowledge on Mullerian mimicry in aculeate wasps and bees. It argues that aculeates may be one of the most diverse groups of mimetic organisms and that the diversity of their mimetic interactions is currently underexplored.
Reproductive and worker castes of termites differ greatly in their morphology and behavior but also in their fertility and longevity. Kings and queens of the highly social termite, Macrotermes natalensis, live for decades, with the queen laying thousands of eggs per day. Workers are sterile and only live a few weeks. In our HFSP project, we investigated the regulatory mechanisms involved in generating such diverse phenotypes. Our previous results indicate that well-regulated transcription allows reproductive castes to overcome simultaneously several well-known hallmarks of aging.

Emmanuelle d’Alençon (UMR DGIMI, Montpellier) and Emmanuelle Jacquin-Joly (UMR iEES-Paris CReA –EcoSens, Versailles) had the pleasure of organizing the 11th international workshop on the molecular biology and genomics of the Lepidoptera. For nearly 30 years, this workshop has brought together the international scientific community working on butterflies and moths every 3 years. Thirteen nationalities met this […]

Since 2016, the Institute of Ecology and Environmental Sciences (iEES Paris) at the Sorbonne University in Paris has been using the Vaisala Continuous Monitoring System to record data in real time and control the temperature and humidity of chambers used for insect breeding and experimentation. The IEES develops innovative strategies and tools for the rehabilitation of damaged environments, the ecologically sustainable management of biological resources and ecosystem services, and adaptation to global change.

Kings and queens of social termites can live for decades, while queens sustain a nearly maximal fertility. We found that they defy aging by multiple gene expression and metabolic changes, while permitting extreme fertility in queens.
