“…PCoA, STRUCTURE, and AMOVA results based on microsatellite data all supported a two-lineage structure for the 10 different geographic populations of the bamboo locust. This finding is different from a previous report on this species (Liu et al, 2016). In fact, the two lineages are distinct in their genetic components and geographic origins.…”

“…migratoria , Danaus plexippus , and Aedes aegypti (Ma et al, 2012;Pfeiler et al, 2017;Liu et al, 2019). Furthermore, the phylogenetic tree of haplotypes showed that most haplotypes of the bamboo locust were clustered on one branch without obvious genetic structure, which was consistent with previous C. kiangsu results (Fan et al, 2014;Liu et al, 2016).…”

“…Moreover, it is difficult to predict the occurrence and dispersal of the locust populations for effective prevention and control because of our limited knowledge of the population structure, ancestral source, and dispersal route of the bamboo locust. Previous studies found that the bamboo locusts are monophyletic with low population differentiation and genetic diversity, and have no significant correlation with geographical distance (Fan et al, 2014;Liu et al, 2016). Microsatellite data showed that historical genetic exchange was frequent, and most of the genetic variation among individuals was within populations (Liu et al, 2016).…”

The genetic structure of species is shaped by several natural and non-natural factors. Although geographical isolation and natural barriers are important causes of genetic structure formation of species, the effects of dispersal potential and population outbreaks remain controversial. Here, we explored this issue in a migratory locust, Ceracris kiangsu, which is an important pest that feeds on bamboo in East and Southeastern Asia. Based on 187 newly sequenced and 286 previously sequenced mitochondrial COI fragments, and 8 nuclear microsatellite loci, we studied the genetic diversity and population genetic structure of C. kiangsu. Both molecular markers revealed high genetic diversity of the geographic populations that possibly resulted from the high flight capacity of the locust. The degree of genetic differentiation among populations was also high, and Mantel test showed that it was significantly correlated with geographical distance. Principal coordinate analysis and STRUCTURE results revealed two genetically different groups, a South China (S-China) Group and a Southeast Asia (SE-Asia) Group. Climate variables well explained the population genetic structure. The demographic history showed that the S-China Group experienced population expansion in the Holocene, whereas the SE-Asia Group was consistently stable. A southeast population (Guangxi) might have been a refuge prior to Holocene expansion. Our study demonstrates a distinct population structure maintained in this migratory insect and reveals the potential effect of past climatic change, geographical isolation, and ecological factors on the evolution of their genetic structure.
