Summary This paper is concerned with some aspects of the ecology of the southern green stink bug, Nezara viridula , in Hawaii. Dispersal studies on adults showed an asymetrical dispersal pattern. The rate of plant to plant to movement by the adults was 3.3–6.7 feet per day. Mortality studies showed that egg predation by ants, Pheidole megancephala , was as high as 80–90 per cent. Egg parasitism by Telenomus basalis was highest during February, 1965, and adult parasitism by Trichopoda pennipes was highest during July, 1964, to January of the following year. The population of N. viridula declined during May, 1964, to May, 1965. This decline occurred simultaneously with the decline in the number of eggs produced per female. It has been speculated that this reduction in egg production was caused by parasitism by T. pennipes .
