Spread Rate
The adult moth is a good flier; larvae are also concealed (tunneled) into stalks so could be some spread in that way.
4
Spread Amount
I believe it would infest the area of corn production, environmental conditions in CA should not present any limitations unless the "lack" of a winter is a problem but this is doubtful.

Ecological
Increased insecticide usage would result to manage this pest if it established - this could threaten environmental quality.

Agricultural
Infests corn; reduces yield in field corn and is a contamination in sweet corn; perhaps some other grassy weed hosts but no other crop hosts.

Detection
Adults can be easily sampled with pheromone traps; larvae are hidden.
4
Control
Can be controlled with Bt-field corn, but this is an added expense for growers and varieties with this technology are not adapted for CA growing conditions; could be very problematic for sweet corn.
