Spontaneous morphogenetic juvenilization observed in laboratory populations of vector species of Chagas disease (Triatominae)
Reported are observations on spontaneous occurring morphogenetic juvenilization in laboratory populations of vector species of Chagas disease. Two general effects have been observed: arrested development and uncoordinated development. These are manifested by supernumerary nymphs (6th stage), interme...

Reported are observations on spontaneous occurring morphogenetic juvenilization in laboratory populations of vector species of Chagas disease. Two general effects have been observed: arrested development and uncoordinated development.

The reoccurrence of insects with identical grades of juvenilization in the population is an indication that this is a genetic trait that might be inherited.
