The need to evaluate non-target effects of classical biological control of arthropod pests has received considerable attention in recent years. We determined with repeated field surveys the changes in abundance and distribution of the phytoseiid mite fauna in cassava fields resulting from the int...

Two countrywide surveys were conducted in April-May and May-June 2004 throughout the cassava growing belt of Mozambique including several provinces: Gaza, Inhambane, Sofala, Manica, Zambezia, Nampula and Cabo Delgado. Both surveys were planned to assess the distribution, incidence and damage seve...

Consideration of possible side-effects of exotic biological control agents on their new environments is a necessary step in classical biological control programs. The evaluation of such effects usually requires the knowledge of the fauna present in those environments prior to introduction of cont...
