abstract

  • An experiment to control the cassava green spider mite (CGM) Mononychellus tanajoa Bondar, an exotic pest of cassava, using an exotic predator Typhlodromalus aripo in cassava fields in the transition forest in Nigeria revealed a significant effect on the severity of cassava diseases. High population densities of T aripo/cassava leaf in cassava fields were associated with low disease severity of cassava bacterial blight, cassava anthracnose disease and African cassava mosaic disease. Also, the population densities of the T aripo did not have a significant effect on the severities of cercospora leaf blight, brown leaf spot and white leaf spot. Controlling the CGM using T aripo therefore reduced the severity of 3 most important diseases of cassava in the transitional forest zone. (C) 2002 Published by Elsevier Science Ltd.
