Aerial Applications for Control of Amorbia Cuneana (Lepidoptera

Tortricidae) ON AVOCADOS, DEC 1980: In an unreplicated test, 3 insecticides were applied to 6-yr-old commercially grown avocado trees (15 ft x 20 ft spacing) located in Riverside County, CA. Each material was applied by helicopter at 20 gal/acre finished spray to a single row of trees, or approximately 0.5 acre. Test rows were separated by at least 6 untreated buffer rows. Fifteen A. cuneana nests were examined on each of 10 trees/treatment for live larvae. The same trees were sampled both pre- and post-treatment. Nests were randomly sampled from both inner and outer areas of the tree from a height of 1-8 ft above ground. Nests were not sampled more than once unless reconstructed by larvae.
