Cucurbit aphid-borne yellows virus (CABYV) was first isolated in southern France in 1988. It causes, mostly in cucurbits, more or less severe yellowing diseases according to the season and cultivar. CABYV infects several weed species and is readily transmitted in a persistent manner by ubiquitous aphids that provide an efficient means of invasiveness worldwide. Symptoms of CABYV are similar to other biotic or abiotic disorders and dating first occurrences of the virus was difficult until appropriate diagnostic methods were developed.

Le virus de la jaunisse des cucurbitacées transmise par puceron (Cucurbit aphid-borne yellows virus, CABYV) infecte, dans les conditions naturelles, les cucurbitacées cultivées mais également d’assez nombreuses plantes adventices annuelles qui ont un cycle hivernal (capselle, lamier, séneçon) ou pérennes (bryone) qui peuvent constituer, entre deux cultures, des réservoirs efficaces de virus mais aussi des pucerons vecteurs.

CONT

Infected cucurbit plants initially show a chlorotic (yellow) spotting, which eventually develops into a striking interveinal chlorosis (yellowing) in which the veins remain more or less green but the rest of the leaf turns bright yellow. Leaves will often roll upward and become brittle. Fruit on infected plants may appear normal but often have reduced levels of sugars; this results in poor marketability and economic loss. Symptoms of Cucurbit yellow stunting disorder virus infection can be confused with abiotic factors, such as nutrient deficiency.

DEF

Nom donné à la diminution de la couleur verte chez les végétaux supérieurs.
