Targeted worker removal reveals a lack of flexibility in brood transport specialisation with no compensatory gain in efficiency
Mahmut Selman Sakar, Laurent Keller, Fazil Emre Uslu
Division of labour is widely thought to increase the task efficiency of eusocial insects. Workers can switch their task to compensate for sudden changes in demand, providing flexible task allocation. In combination with automated tracking technology, we de ...
2024Alfalfa leaf curl virus is efficiently acquired by its aphid vector Aphis craccivora but inefficiently transmitted
Faustine Ambroisine Charline Ryckebusch
Alfalfa leaf curl virus (ALCV) is the first geminivirus for which aphid transmission was reported. Transmission by Aphis craccivora was determined previously to be highly specific and circulative. Using various complementary techniques, the transmission jo ...
MICROBIOLOGY SOC2021Blind killing of both male and female Drosophila embryos by a natural variant of the endosymbiotic bacterium Spiroplasma poulsonii
Bruno Lemaitre, Samuel Rommelaere, Florent François Masson, Juan Camilo Paredes Escobar, Mario Gonzalo Garcia Arraez
Spiroplasma poulsonii is a vertically transmitted endosymbiont of Drosophila melanogaster that causes male-killing, that is the death of infected male embryos during embryogenesis. Here, we report a natural variant of S. poulsonii that is efficiently verti ...
WILEY2020Unsteady fluid dynamics around a hovering flat plate wing
Insect flight is characterised by complex time-dependent flows in response to the unsteady wing movements. Biological fliers exploit the unsteady flow fields to modulate aerodynamic forces, thereby displaying unmatched flight performance, especially in hov ...
EPFL2017Cell Division by Longitudinal Scission in the Insect Endosymbiont
Bruno Lemaitre, Graham Knott, Catherine Maclachlan, Elodie Julie Virginie Ramond
Spiroplasma bacteria are highly motile bacteria with no cell wall and a helical morphology. This clade includes many vertically transmitted insect endosymbionts, including Spiroplasma poulsonii, a natural endosymbiont of Drosophila melanogaster. S. poulson ...
American Society for Microbiology2016Spiroplasma and host immunity: activation of humoral immune responses increases endosymbiont load and susceptibility to certain Gram-negative bacterial pathogens in Drosophila melanogaster
Bruno Lemaitre, Jeremy Keith Herren
Spiroplasma poulsonii and its relatives are facultative, vertically transmitted endosymbionts harboured by several Drosophila species. Their long-term survival requires not only evasion of host immunity, but also that Spiroplasma does not have a net detrim ...
