Methods Used to Study

• PCR amplification and sequencing.
• tRNA genes were identified by using tRNAscan SE
  and DOGMA

Questions

• Are Sternorrhyncha Monophyletic?
• Issues concering the uncertain relationships
  among scale insect families and their inability
  to obtain consensus on the rank and name for
  higer taxa.
