Quantifying supply and demand in the pea aphid-Buchnera symbiosis reveals the metabolic Achilles’ heels of this interaction Open
Many herbivorous insects feed on unbalanced diets and rely on bacterial endosymbionts to meet all their nutritional needs. This is the case for the pea aphid (Acyrthosiphon pisum), a plant pest whose remarkable growth and reproductive capa…

NPF signaling-dependent maintenance of metabolic homeostasis in the pea aphid is mediated by a highly selective ligand-receptor interaction and tissue-specific changes in NPF and NPFR Open
Neuropeptide F (NPF) and its receptor (NPFR) are important regulators of food intake, physiology and metabolism in insects. Focusing on a major crop pest, the pea aphid Acyrthosiphon pisum, it is shown that the predicted NPFR is a highly s…

Discovery of an Insect Neuroactive Helix Ring Peptide from Ant Venom Open
Ants are among the most abundant terrestrial invertebrate predators on Earth. To overwhelm their prey, they employ several remarkable behavioral, physiological, and biochemical innovations, including an effective paralytic venom. Ant venom…

Bacteriocyte plasticity in pea aphids facing amino acid stress or starvation during development Open
An important contributing factor to the evolutionary success of insects is nutritional association with microbial symbionts, which provide the host insects with nutrients lacking in their unbalanced diets. These symbionts are often compart…
