Control. — Submersion, when possible, is a quick and thorough means 

 of exterminating the pest, but of course this is limited to irrigated 

 districts. The fields should be flooded soon after the crop is harvested 

 and the water left standing over the vines for four or five days. The 

 destruction of weakened and infested plants is also recommended to 

 prevent the spread of the moth. Valuable plants can be protected with 

 screens or netting to prevent the moths depositing their eggs upon them.
