Abstract
The populations of Spilonota ocellana (D.&S.) on two cultivars in an insecticide free orchard showed nearly identical trends over a 12-year period. Egg populations reached maximum numbers when the orchard was 9 years old and the ensuing larvae infested 33% of the clusters the following year. A marked decline in all stages occurred when the orchard was 11 to 12 years old and this was immediately followed by a second peak of less intensity on both cultivars. The only difference in mortality of the population on the two cultivars was found in neonate larvae. The average survival of egg to pupa for the 12-year period was near 7%.This publication has 9 references indexed in Scilit:
