Drosophiles and social learning

The behaviour named social learning is generally considered to be displayed by evolved animals such as apes. Yet, Frédéric Méry’s team in collaboration with the team of the Hubert Curien Pluridisciplinary Institute in Strasbourg showed that drosophila are able to display such a behaviour when chosing the site to lay their eggs. This work was published in the Proceedings of the Royal Society, serie B.

Helping bees

Lionel Garnery (Evolbee) has been promoted to the head of the Fédération des Conservatoires de l’abeille noire (FEDCAN). This structure will set up a network with the various conservatories and will participate in making them more visible for the general audience. The objectives of the bee conservatories is to prevent the hybridizations of black bees with other bees and to allow them to live under conditions close to wild life. FEDCAN will also try to standardize bee keeping methods.

A case where female drosophilas mimick males

The work of Jean David (IGGIPOP), Amir Yassin and colleagues on the variability of females of Drosophila erecta was published in Nature Communications. The authors showed that one gene, the tan gene, was responsible for the existence of two types of females, one ressembling the males with a black abdomen and the other harboring a white abdomen.

The females with black abdomen would have an advantage when sexual competition is at its top because they are less attractive and hence are less subjected to sexual harrassment from the males. This would maintain this variability of abdomen coloration of females which appears to date from long ago.
