Considerations of the migration in the smaller tea tortrix, Adoxophyes honmai (Lepidoptera: Tortricidae), by comparisons of the insecticide susceptibilities

Abstract

In order to gain knowledge of the migration of the smaller tea tortrix, Adoxophyes honmai Yasuda (Lepidoptera: Tortricidae), we compared the insecticide susceptibilities of two A. honmai strains. A conventional control strain and an organic farming strain were collected from two adjacent tea fields. Results showed that the two A. honmai strains indicated similar susceptibilities to the 13 insecticides tested, showing that the A. honmai moths migrated at a high frequency between the two adjacent tea fields.
