DeLoach (1978) studied the biology of this moth.


Niphograpta albiguttalis was released at 20 sites in Florida in 1976. It became established at or near 16 sites and continued to spread beyond these sites (Center and Durden 1981).


This moth is probably wide spread and continues to contribute to the biological control of water hyacinth.


A variety of release methods are successful (Center and Durden 1981). Establishment was best when 1st instar larvae were release during October through March. Populations established best on young plants with good growth.
