Table 1.
Observed microsatellite Multi Locus Genotypes (MLG): allele size (bp) at each locus, distribution by host plant and in each of the five Multi Locus Lineages (MLL) defined with GENCLONE. Within MLL allelic variations are in bold.
Figure 1.
Minimum spanning network of Melanaphis sacchari microsatellite distances computed as the number of allele differences between MLGs. Each node represents one step in the network, i.e. a distance of one allele.
The numbers in the circles represent MLGs according to Table 1. Coloured backgrounds represent the Multi Locus Lineages (MLLs). MLGs in the same dashed line box share the same COI haplotype.
Figure 2.
COI haplotype network (top), in which Melanaphis sacchari COI sequences originating from the present study are numbered from 1 to 3.
M. sacchari GenBank COI sequences from India [44] are numbered 4 (JX051388, JX05189, JX051390) and 5 (HQ112185, JX051402). Mj = Melanaphis japonica COI sequence from GenBank (GU457792). Distribution as a function of host plant (middle): sorghum (blue) vs. sugarcane (red). Distribution as a function of MLL (bottom): A (green), B (blue), C (yellow), D (violin), E (red).
Figure 3.
Factorial correspondence analysis of microsatellite data with GENETIX.
Each symbol represents one of the 36 MLGs. Colours and letters refer to Multilocus Lineage (MLL) assignment with GENCLONE.
Figure 4.
Relative geographical within-state distribution of Multilocus lineages (MLL).
The size of circle is not proportional to the size of the sample. Aus = Australia, Bra = Brazil, Col = Columbia, Ecu = Ecuador, Gua = Guadeloupe, Haw = Hawaii, Lou = Louisiana, Mar = Martinique, Mau = Mauritius, Run = Reunion Island, Ben = Benin, Cam = Cameroon, Nig = Niger, Chi = China, Ken = Kenya.
