Resistance to Frankliniella occidentalis in cucumber
Experiments in the Netherlands were implemented to test various cucumber accessions in respect to their resistance to Frankliniella occidentalis (EPPO A2 quarantine organism). Several hundred cucumber accessions were tested and it was found that several accessions showed a fairly high level of resistance. Resistant accessions had an effect on the biology of F. occidentalis by negatively influencing their survival and reproduction. It was also found that the accessions with the highest level of resistance additionally showed resistance to spider mites. The authors concluded that the obtained results provide encouraging and good prospects for future resistance breeding programmes.
