- Abstract
1 The red turpentine beetle,Dendroctonus valensLeConte, is a recent New World introduction to the People's Republic of China. An outbreak of these beetles has infested over 0.5 million hectares of pine forests.2 Efforts are underway to suppress this outbreak using biological control measures. However, the wide distribution in the native range ofD. valenssuggests regional variation of the beetle's biology, predators, and parasitoids. Thus, knowledge of the origin of these beetles can help devise precise and effective control measures.3 A portion of the mitochondrial cytochrome oxidase subunit I gene was sequenced for 218 individuals from 32 populations throughout the native range ofD. valensand in China.4 Haplotype diversity was high. A total of 131 haplotypes were found and Jukes–Cantor corrected nucleotide difference ranged from 0 to 16%. Haplotype diversity ranged from 0.53 to 0.98 and unique haplotypes were found in most populations.5 Parsimony and statistical parsimony analyses of these haplotypes support the hypothesis that the introduction ofD. valensto China was recent and originated from the Pacific North-west of the U.S.A.6 In addition, the high haplotype diversity also suggests a large or multiple introductions. However, based on the genetics of the beetle's reproductive behaviour, this diversity may also be explained by a limited number of individuals or introductions.
