Brachycaudus helichrysi est un puceron ravageur des cultures qui inflige de sérieux dégâts à ses hôtes primaires (arbres fruitiers du genre Prunus) ainsi qu'à plusieurs herbacées cultivées correspondant à ses hôtes secondaires (par exemple les tournesols et les chrysanthèmes).L'étude phylogéographique de l'espèce basée sur un échantillonnage mondial, montre que B. helichrysi rassemble deux taxa appelés B. helichrysi H1 et H2. Cette étude, basée sur plusieurs marqueurs génétiques (mitochondriaux, nucléaire et bactériens), révèle une divergence génétique de l'ordre de celle observée entre espèce du genre Brachycaudus. Ceci suggère que B. helichrysi H1 et H2 sont deux espèces sœurs. Comme H1 et H2 sont morphologiquement indistinguables, nous a...
