Perhaps there will be some in three or four days, he said, but then the drought cycle undoubtedly will start over again.

Swarming populations can then perpetuate themselves for a number of years, requiring an intense control effort, before gradually dying out during another drought cycle.

This property can prevent root rot and moderate drought cycles.
