 note = {A leafminer, Liriomyza trifolii, is a polyphagous insect giving aethetical damage and in the most severe case growth damage to florists' chrysanthemum. The author reported that Dendranthema arcticum and D. zawadskii are higher resisitance species to this insect than other species so far reported. As a preliminary step to start a breeding programme for resistance of florists' chrysanthemum to L. trifolii using these species, a collection trip in Hokkaido was organised from 4 to 10, October 1998. In total, 86 strains of D. arcticum and 15 strains of D. zawadskii were collected during the trip. The collected strains will be propagated and assessed for the resistance to L. trifolii during the next years.},
