Abstract: A study of biological control of waterhyacinth using a native moth, Arzama densa Walker, is presented herein. Previous studies have shown that the larvae, in sufficient numbers, can severely damage populations of the target aquatic plant. Workers in biocontrol generally feel that if sufficiently large populations of the insect could be produced to supplement field populations, this agent could be an effective tool in limiting infestations of waterhyacinth. The study reported herein includes the biology of the insect and effects of various diets on the insect's growth. This report also describes the most successful rearing methods found thus far for Arzarna densa.
