Summary

Field efficacy of entomopathogenic fungi to control Rhagoletis cerasi.
Two myco-insecticides, Naturalis-L (Beauveria bassiana) and PreFeRal®WG (Paecilomyces fumosoroseus), were applied against adult R. cerasi Loew (Diptera: Tephritidae) in two orchards in north-western Switzerland in summer 2006. Both products were able to cause mycosis on adult flies under field conditions. However, only Naturalis-L significantly reduced the number of damaged fruits (efficacy: 69-74%), whereas damaged fruits were not significantly reduced with PreFeRal (efficacy: 27%). For B. bassiana living fungal propagules were still detectable seven days after application while the fungal propagules of P. fumosoroseus remained only three days. A control of R. cerasi with myco-insecticides seems possible under field conditions; however, the application regime still has to be improved.
