The screening for insects carrying SoSGV. a Images of the insects caught in a SoSGV-infected soybean field in Suzhou, Anhui Province. Scientific names at the rank of species, genus, or family were shown. Bars = 2.5 mm. b The detection of SoSGV by PCR from total DNA extracted from insects shown in panel a. Two primer pairs were used. Primers #2906 and #2907 were used for PCR 1. Primers #2904 and #2905 were used for PCR 2. The expected amplicon lengths for PCR 1 and 2 are 1008 bp and 768 bp, respectively. The PCR products amplified from each insect were loaded to DNA gels in the order of insect species shown in panel a. Water and a plasmid containing SoSGV genome DNA were used as negative (N) and positive (P) controls, respectively
