Watermelon silver mottle virus: a new member of the genus tospovirus
In China, very serious outbreaks of Helicoverpa armigera (EPPO A2 quarantine pest) in cotton have recently been reported (EPPO RS 94/056). During 1992 and 1993, this outbreak has been kept under good control in the Xinxiang (Henan province) demonstration area, located in the central part of the Yellow River valley. An IPM programme has been set up, based on the monitoring of first generation populations, timely applications of products according to various action thresholds against the different generations, management of insecticide resistance, management of natural enemies and use of resistant cotton cultivars.
