Metodo Para Probar Transmision Transovarica de Patogenos Por Trialeurodes Vaporariorum Y Resultados Con El Causante Del"amarillamiento de Venas de la Papa"

Abstract

Spanish

Yellow vein disease of potatoes is a serious disease in Colombia (Antioquia, and Nariño) and Ecuador. It is important to acquire full knowledge of the pathogen and its vector, the greenhouse whitefly, Trialeurodes vaporariorum (Westwood) (Homoptera: Aleyrodidae), in order to achieve a correct management of the disease. Research conducted at the ICA Experimental Station "La Selva" in Rionegro (Ant.), testing a method to evaluate vector pathogen relation-ships allowed to conclude that: There is not trans-ovaric transmission of the pathogen, and there is a semipersistent vector pathogen relationship. The method tested utilized very young nymphs still able to move. 67.7% of them arrived to the adult stage.
