What Does the Future Hold?

  • Scanning electron microscopy- A new technology created in 2007 to figure out the form and ways of an egg and maggots. Requires the use of expensive equipment.

  • Potassium permanganate staining- When scanning cost too much this is the easier way to go. Involves only a few steps ..

  • Mitochondrial DNA- A method created in 2001, that uses mitochondria DNA to differentiate between different species of the subfamily.
