Biology
DeLoach (1978) studied the biology of this moth.
History
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).
Status
This moth is probably wide spread and continues to contribute
to the biological control of water hyacinth.
Management
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.
Weeds Affected
Niphograpta albiguttalis host range was studied by
Cordo and DeLoach (1978).
