Abstract To evaluate the insect resistance of a new Zizania latifolia variety‘Longjiao No.2’,the
resistence of‘Longjiao No.2’and other two control varieties,‘Suozijiao’and‘Zhejiao 911’to
Chilo suppressalis and Saccharosydne procerus were identified by using surviving rate evaluation
method.The results showed that‘Suozijiao’was susceptible to Saccharosydne procerus,‘Zhejiao 911
’was medium resistant,while‘Longjiao No.2’was resistant，and‘Longjiao No.2’was medium
resistant to Chilo suppressalis among the tested three varieties.The method of low temperature
treatment was used to evaluate the cold tolerance of the three varieties.Result indicated that
‘Longjiao No.2’had better cold tolerance than the control varieties‘Suozijiao’and‘Zhejiao 911
’.
