Fig 1. Classification of the South African mealybug species collected from cassava using 18S rRNA.

Phylogenetic tree of Phenacoccus species derived from the maximum likelihood analysis of 18S rRNA sequences. Mealybug samples collected in the current study (colour-shaded) clustered with Phenacoccus manihoti 18S RNA sequence (Genbank accession number JQ651008.1) confirming their identity. Bootstrap values were calculated from 10 000 replicates.
