초록

Riptortus pedestris (Fabricius) has caused severe agricultural damage in Asian regions. To clarify genetic relationships among different populations of R. pedestris in Korea, 294 COI sequences were generated from 294 individual samples collected in 42 local regions. In total, 36 haplotypes were detected from the 294 COI sequences, and the genetic distances among the 42 local populations ranged from 0.00 % to 1.50 %. In the AMOVA results, a variability of more than 98 % was observed within populations, and the median joining (MJ) networks revealed that R. pedestris has expanded by crossing the nine geographical groups. Most of the samples shared one haplotype, H2; however, some samples obtained from the same regions displayed slight genetic differences. These results indicate that R. pedestris have undergone a series of genetic variations.
