“…The genetic diversity of species is closely associated with their ecological adaptations, which have been explored in many species especially in invasive alien species192324. In this study, unique mtCOI haplotypes have been identified in many populations from the GMS, which indicates that the adaptation of these haplotypes are a response to the local environment including the unique climate, host plants, and agricultural activities experienced by the population from that particular region.…”

“…Approaches involving population genetics such as the use of mitochondrial and nuclear microsatellite markers can provide essential tools for overcoming these problems151617181920. Previous study has demonstrated the genetic differentiation in S. furcifera from five disjunct localities in Korea, the Philippines, China (only two populations), Malaysia, and Vietnam using mitochondrial sequences.…”

The white-backed planthopper, Sogatella furcifera (Horváth) (Hemiptera: Delphacidae), is a serious pest of rice in Asia. However, little is known regarding the migration of this pest insect from the Greater Mekong Subregion (GMS) including Cambodia, Laos, Myanmar (Burma), Thailand, and Vietnam, into China’s Yunnan Province. To determine the migration patterns of S. furcifera in the GMS and putative secondary immigration inside China’s Yunnan Province, we investigated the population genetic diversity, genetic structure, and gene flow of 42 S. furcifera populations across the six countries in the GMS by intensive sampling using mitochondrial genes. Our study revealed the potential emigration of S. furcifera from the GMS consists primarily of three major sources: 1) the S. furcifera from Laos and Vietnam migrate into south and southeast Yunnan, where they proceed to further migrate into northeast and central Yunnan; 2) the S. furcifera from Myanmar migrate into west Yunnan, and/or central Yunnan, and/or northeast Yunnan; 3) the S. furcifera from Cambodia migrate into southwest Yunnan, where the populations can migrate further into central Yunnan. The new data will not only be helpful in predicting population dynamics of the planthopper, but will also aid in regional control programs for this economically important pest insect.

“…had in 2009, but we failed to detect the Q biotype using the specific mtCOI primers used in the present study (see section 2.2) or mtCOI sequencing as in our previous research31, implying that the Q biotype previously invaded Fujian, but failed to colonize it before 2012. Multiple secondary introductions, however, may be an important prerequisite for the establishment of the Q population in the fields37.…”

“…Thus, high temperatures ≥35 °C, which appear in the open fields and often exist in protected areas, may have contributed to the results in this paper, specifically the colonization of the Q biotype and its proportional increase in whitefly population. Chu et al 37. demonstrated that wide use of the protected agriculture in northern China promoted the colonization of the Q biotype in agricultural fields.…”

The whitefly Bemisia tabaci (Gennadius) is an important agricultural insect pest worldwide. The B and Q biotypes are the two most predominant and devastating biotypes prevalent across China. However, there are few studies regarding the occurrence of the Q biotype in Fujian Province, China, where high insecticide resistance has been reported in the B biotype. Differences in some biological characteristics between the B and Q biotypes, especially insecticide resistance, are considered to affect the outcome of their competition. Extensive surveys in Fujian revealed that the B biotype was predominant during 2005–2014, whereas the Q biotype was first detected in some locations in 2013 and widely detected throughout the province in 2014. Resistance to neonicotinoids (that have been used for more than 10 years) exhibited fluctuations in open fields, but showed a continual increasing trend in protected areas. Resistance to lambda-cyhalothrin, chlorpyrifos, and abamectin exhibited a declining trend. Resistance to novel insecticides, such as nitenpyram, pymetrozine, sulfoxaflor, and cyantraniliprole, in 2014 was generally below a moderate level. A decline in insecticide resistance in the B biotype and the rapid buildup of protected crops under global temperature increase may have promoted the establishment of the Q biotype in Fujian.

“…Following its introduction to new areas, B. tabaci Med is replacing the previously common B. tabaci MEAM1 (e.g. Chu et al 2010, Pan et al 2011, and multiple introductions from several sources to a particular area can contribute to increased genetic diversity potentially leading to improved adaptation to new environments (Chu et al 2014 …”

We surveyed 13 Finnish and 13 Swedish poinsettia greenhouses in 2006 for Bemisia tabaci biotype Q (currently B. tabaci Mediterranean) and determined the biotype status of B. tabaci populations with PCR followed by an RFLP assay. We collected approximately 100 adult whiteflies from yellow sticky traps or from plants and stored them in 80% ethanol until DNA extraction. Total nucleic acids of two to five whiteflies per sample were extracted using FTA cards or a modified Chelex method. We showed that biotype Q was present in 10 out of 13 whitefly samples from Finnish poinsettia greenhouses and in 12 out of the 13 Swedish poinsettia greenhouses sampled. We also determined the whitefly biotypes from yellow sticky traps. The common occurrence of insecticide-resistance-prone biotype Q whiteflies on poinsettia imported into Finland and Sweden, both protected zones for B. tabaci, emphasizes the importance of preserving the quarantine status of the pest to prevent permanent establishment. Nonetheless, the increasing occurrence of a resistance-prone biotype on imported plant material will complicate preservation of the protected zone status if solely insecticides are used to control the pest.
