西部干白蚁Incisitermes minor（哈根）和南部轻白蚁I. snyderi（Light）分别是美国西南部和南部常见的干木白蚁。尽管这两个物种的经济重要性，没有信息存在的线粒体遗传多样性的I。小的和我snyderi。一项分子遗传学研究，涉及部分线粒体的DNA测序! DNA 16S rRNA基因分析表明，在16S rRNA基因的多态性范围内，I.小的和我snyderi。共观察到12种单倍型。采集自佛罗里达、俄勒冈州、亚利桑那州、得克萨斯州、犹他州和加州的小的。对我来说。snyderi，共观察到10个单倍型来自巴哈马，佛罗里达，格鲁吉亚，和得克萨斯州。I.次要单倍型的变异范围为0.7~3.7%，I. Snyderi的范围为0.7 - 2.4%。最大简约法和最大似然法分析表明，I. snyderi，而我。minor有两个不同的分支。这是首次对干白蚁线粒体遗传变异的研究。小的和我snyderi。似乎有足够的遗传变异，这2个物种的分子生物地理学研究，这可能会提供深入了解这些物种的传播和引进。
The western drywood termite, Incisitermes minor (Hagen) and the light southern drywood termite I. snyderi (Light) are common drywood termites in southwestern and the southern United States, respectively. Despite the economic importance of these 2 species, no information exists on the mitochondrial genetic diversity of I. minor and I. snyderi. A molecular genetics study involving DNA sequencing of a portion of the mitochondria! DNA 16S rRNA gene was undertaken to determine the extent of genetic variation in I. minor and I. snyderi. A total of 12 haplotypes were observed for I. minor collected from Florida, Oregon, Arizona, Texas, Utah, and California. For I. snyderi, a total of 10 haplotypes were observed from the Bahamas, Florida, Georgia, and Texas. Genetic variation among I. minor haplotypes ranged from 0.7 to 3.7% and variation for I. snyderi ranged from 0.7 to 2.4%. Maximum parsimony and maximum likelihood analysis revealed 3 distinct clades for I. snyderi, whereas, I. minor had 2 distinct clades. This is the first study on mitochondrial genetic variation of the drywood termites I. minor and I. snyderi. There appears to be enough genetic variation within these 2 species for a molecular phylogeographic study, which may provide insight into dispersal and introductions of these species.
