The seasonal occurrence of two Tortricinae species, Adoxophyes honmai (Yasuda) and Homona magnanima Diakonoff, was monitored at persimmon orchard in Changwon city, Gyeongnam, using sex attractant traps in 2012 and 2013. During the monitoring, a number of Neocalyptis angustilineata (Walsingham) was attracted to sex pheromone traps of H. magnanima. For A. honmai, a blend of Z9-14Ac, Z11-14Ac, E11-14Ac, 10me-12Ac with the ration of 314, 623, 55, and 9 ㎍ respectively, was used. A blend of Z11-14Ac and Z9-12Ac in the ratio of 900+100 ㎍ was used for H. magnanima. A 1:1 blend of Z11-14Ac and Z9-12Ac (500+500 ㎍) was also used for N. angustilineata. The two-years’ monitoring revealed that A. honmai and H. magnanima occurred four times a year, and N. angustilineata did three times. The peak occurrence of each generation for A. honmai was the 2nd or 3rd week of May, the 1st to 2nd week of July, and 5th week of July to 1st week of August, and 2nd to 4th week of September for the 1st, 2nd, 3rd, and 4th generation, respectively. The peak occurrence of each generation for H. magnanima was the 3rd to 4th week of May, the 2nd to 3rd week of July, and 4th week of August to 1st week of September, and 4th week of September to 3rd week of October for the 1st, 2nd, 3rd, and 4th generation, respectively. N. angustilineata showed clear three peaks of the 5thweek of May to 1st week of June, from 4th to 5th week of July, and 1st to 3rd week of September for the 1st, 2nd, and 3rd generation, respectively.
A significantly higher number of N. angustilineata was attracted to sex pheromone traps of H. magnanima for the two years than H. magnanima was. H. magnanima was attracted only to the 9:1 blending ratio. However, N. angustilineata was attracted equally to both of the blending ratios.
