Mastotermes darwiniensis, the Giant Northern Termite, is the
most primitive of the commercially significant species. It
shows an ability for sub-colonies to split from the main colony
and produce queens, without a mating flight. Eventually a network
of interconnecting sub-colonies is established, which makes
control difficult. These large termites can devastate buildings,
bridges, poles, trees and crops such as sugarcane. Mastotermes
is found mainly north of the Tropic of Capricorn.
