Cacao swollen shoot virus, invasive species, Theobroma cacaoAbstract
Cocoa swollen shoot virus disease is an important virus disease of cocoa occurring mainly in West Africa. Mealybugs are known to be vectors of the pathogen, Cacao swollen shoot virus. Since recent outbreaks in Côte d’Ivoire, studies have been undertaken on different aspects of the disease. During 2013, surveys were conducted to identify mealybug species infesting aerial parts of cocoa (Theobroma cacao L.; Malvales: Malvaceae) trees at various sites and the samples were authoritatively identified using morphological characters. A species new to Africa, Pseudococcus jackbeardsleyi Gimpel & Miller (Hemiptera: Pseudococcidae), was found at 2 localities in Côte d’Ivoire, i.e., Buyo (Soubré county) and Gbalékro (Agboville county). Hosts of this polyphagous mealybug belong to 47 plant families and include banana, eggplant, Hibiscus spp., potato, sweet pepper and tomato. Virus transmission by P. jackbeardsleyi has not been recorded, but it belongs to the same genus as P. maritimus (Ehrhorn), which transmits Little cherry virus 2 to sweet cherry, and P. longispinus (Targioni Tozzetti), which transmits Grapevine A trichovirus (GAV) to grapevine and Cacao swollen shoot virus (CSSV) to cocoa. The introduction and establishment of P. jackbeardsleyi in Africa may have a considerable impact on both commercial and subsistence agriculture.
La enfermedad viral de retoños hinchados de cocoa (cocoa swollen shoot virus disease en inglés) es una enfermedad viral importante del cacao que ocurre principalmente en el África occidental. Las cochinillas son conocidas por ser vectores del patógeno, Cacao swollen shoot virus. A partir de los brotes recientes en Côte d’Ivoire (Costa de Marfil) se han realizado estudios sobre diferentes aspectos de la enfermedad. Durante 2013, se realizó un sondeo para identificar las especies de cochinillas que infestan las partes aéreas de los árboles de cacao (Theobroma cacao L; Malvales: Malvaceae) en diferentes sitios y los especimenes recolectadas fueron identificados meticulosamente usando caracteres morfológicos. Se encontró una especie nueva para África, Pseudococcus jackbeardsleyi Gimpel & Miller (Hemiptera: Pseudococcidae), en 2 localidades de Côte d’Ivoire (Costa de Marfil), en Buyo (condado Soubré) y Gbalékro (condado Agboville). Los hospederos de esta cochinilla polífaga pertenecen a 47 familias de plantas e incluyen el plátano, berenjena, Hibiscus spp., papa, chile dulce y tomate. La transmisión del virus por P. jackbeardsleyi no ha sido registrado, pero pertenece al mismo género que P. maritimus (Ehrhorn), que transmite el Little cherry virus 2 a cereza dulce, y P. longispinus (Targioni Tozzetti), que transmite el Grapevine A trichovirus (GAV) y el Cacao swollen shoot virus (VRHC) a cacao. La introducción y el establecimiento de P. jackbeardsleyi en África pueden tener un impacto considerable tanto en la agricultura comercial y como de subsistencia.
