Abstract

The subterranean termite Globitermes sulphureus is commonly found in Malaysia, Singapore, Thailand, and Vietnam (Ahmad, 1965; Bordereau et al., 1997; Kuswanto et al., 2015; Lee et al., 2007; Ngee & Lee, 2002). This termite belongs to higher group termites which possess only bacteria and archaea in their gut (Bujang et al., 2014). As a wood feeder termite, this species has been reported to infest premises’ wood structures (Ab Majid & Ahmad, 2009; Neoh et al., 2011). Moreover, it was also reported as the primary pest in agricultural sectors such as coconut and oil palm plantations (Lee et al., 2003). G. sulphureus is recognized as a pest of significant economic importance in Southeast Asia (Rust & Su, 2012). Abstract The subterranean higher termite Globitermes sulphureus (Blattodea: Termitidae) is a peridomestic forager and regarded as a significant pest in Southeast Asia. In this study, populations of G. sulphureus from the USM main campus area were investigated based on partial sequences of the mitochondrial COII gene. The genetic diversity was determined using DnaSP v5 software, while the phylogenetic relationship was defined using Neighbor-joining (NJ) and maximum likelihood (ML) methods using Molecular Evolutionary Genetics Analysis (MEGA 7) software. A total of 2 haplotypes were detected among 5 sample sequences distinguished through two variable sites. Also, both phylogenetic trees gave similar topology and supporting the results from haplotype diversity. Based on the haplotype diversity and molecular phylogeny, it is proposed that geographic isolation and lack of human activities have contributed to the neutral genetic diversity of G. sulphureus.

高等白蚁gloitermes sulphureus (Haviland)的遗传多样性及系统发育关系(白蚁总目:白蚁科)
地下白蚁Globitermes sulphuurus常见于马来西亚、新加坡、泰国和越南(Ahmad, 1965;Bordereau et al., 1997;Kuswanto et al., 2015;Lee et al., 2007;Ngee & Lee, 2002)。这种白蚁属于高级白蚁群,它们的肠道中只含有细菌和古细菌(Bujang et al., 2014)。作为一种食木白蚁,据报道该物种会侵害房屋的木结构(Ab Majid & Ahmad, 2009;Neoh et al., 2011)。此外,据报道,它也是椰子和油棕种植园等农业部门的主要害虫(Lee et al., 2003)。G.硫脲被认为是东南亚具有重要经济意义的害虫(Rust & Su, 2012)。摘要地下高等白蚁gloitermes sulphureus(白蚁总目:白蚁科)是东南亚地区的一种重要害虫。本研究利用线粒体COII基因的部分序列对来自USM主校区的G. sulphurus种群进行了研究。采用DnaSP v5软件确定遗传多样性,采用分子进化遗传学分析(MEGA 7)软件采用Neighbor-joining (NJ)和最大似然(ML)方法确定系统发育关系。通过两个可变位点区分的5个样本序列共检测到2个单倍型。此外,两种系统发育树给出了相似的拓扑结构,并支持单倍型多样性的结果。基于单倍型多样性和分子系统发育的分析,认为地理隔离和人类活动的缺乏是造成硫柳属植物中性遗传多样性的主要原因。《社会生物学》关于群居昆虫的国际期刊

期刊介绍: SOCIOBIOLOGY publishes high quality articles that significantly contribute to the knowledge of Entomology, with emphasis on social insects. Articles previously submitted to other journals are not accepted. SOCIOBIOLOGY publishes original research papers and invited review articles on all aspects related to the biology, evolution and systematics of social and pre-social insects (Ants, Termites, Bees and Wasps). The journal is currently expanding its scope to incorporate the publication of articles dealing with other arthropods that exhibit sociality. Articles may cover a range of subjects such as ecology, ethology, morphology, population genetics, physiology, toxicology, reproduction, sociobiology, caste differentiation as well as economic impact and pest management.
