Fig. 3 in Odorant-binding protein 2 is involved in the preference of Sogatella furcifera (Hemiptera: Delphacidae) for rice plants infected with the Southern rice black-streaked dwarf virus
Fig. 3. Effects of RNAi of SfurOBP-2 or -11 on the preferences of S. furcifera for healthy, virus-infected rice plants or air (empty pot with soil). The data of nonresponding insects were given on the right of the bar in the figure. Double asterisks indicate statistically significant difference (chi-square test: **P <0.01), NS indicates no significant difference. (A) S. furcifera choice tests between healthy or infected rice plants afer injection of dsRNA or water (Control); (B) S. furcifera choice tests between healthy rice plants or air afer injection of dsRNA or water (Control); (C) S. furcifera choice tests between virus-infected rice plants or air afer injection of dsRNA or water (control).

Fig. 2. Detection of the mRNA levels afer RNA interference. The histogram bars represent mean ± SE of 3 biological replicates. Different letters above bars indicate significant differences (1-way ANOVA: P <0.01). (A) mRNA levels of SfurOBP2 in S. furcifera injected with different dsRNA. RNase-free water injection (Control), EGFP-dsRNA (dsEGFP), SfurOBP2-dsRNA (dsOBP2). (B) mRNA levels of SfurOBP11 in S. furcifera injected with different dsRNA. RNase-free water injection (control), EGFP-dsRNA (dsEGFP), SfurOBP11-dsRNA (dsOBP11).
Fig. 1 in Odorant-binding protein 2 is involved in the preference of Sogatella furcifera (Hemiptera: Delphacidae) for rice plants infected with the Southern rice black-streaked dwarf virus
Fig. 1. Expression profiles of SfurOBP2 and SfurOBP11 in the antennae of virusfree and viruliferous S. furcifera. VFA: virus-free antennae; VIA: virus-infected antennae. The histogram bars represent mean ± SE of 3 biological replicates. Asterisk above bars indicate significant differences (t-test: *P <0.05, **P <0.01).
Immigration of Sogatella furcifera from the Greater Mekong Subregion into northern China revealed by 2b-RAD sequencing
Background The white-backed planthopper (WBPH), Sogatella furcifera (Horváth) (Hemiptera, Delphacidae), is a migratory pest of rice in Asia. Shandong Province, in northern China, is located on the migration pathway of WBPH between southern and northeast China. The potential sources of WBPH in northern China are poorly understood. We studied the sources of WBPH in Shandong Province by determining the population genetic structure of WBPH in 18 sites distributed in Shandong and in six regions of the Greater Mekong Subregion (GMS). We used mitochondrial gene and single-nucleotide polymorphism (SNP) markers (2b-RAD sequencing) for analysis. Results All of the WBPH populations studied in the seven regions had low genetic diversity. Pairwise F ST values ranged from -0.061 to 0.285, while F ST based on SNP data ranged from -0.007 to 0.009. These two molecular markers revealed that 4.40% (mtDNA) and 0.19% (SNP) genetic variation could be explained by the interpopulation variation, while the rest came from intrapopulation variation. The populations in the seven geographic regions comprised four hypothetical genetic clusters (K = 4) not associated with geographic location. Eighty-four of 129 individuals distributed across the given area were designated as recent migrants or of admixed ancestry. Although the substantial migration presented, a weak but significant correlation between genetic and geographic distances was found (r = 0.083, P = 0.004). Conclusion GMS was the main source of WBPH in Shandong, while other source populations may also exist. The genetic structure of WBPH is shaped by both migration and geographic barriers. These results help clarify the migration route and the source of WBPH in northern China.
