Ascarosides coordinate the dispersal of a plant-parasitic nematode with the metamorphosis of its vector beetle

Abstract

Many species of nematodes use pheromones called ascarosides to coordinate their behaviour and development. Here, Zhao et al. demonstrate that the beetle vector of the pinewood nematode (Bursaphelenchus xylophilus) also uses and responds to ascarosides in its interactions with the nematodes.
