Abstract
The aerial dispersal of pink citrus rust mite, Aculops pelekassi（Keifer）, was monitored throughout the 2017 citrus growing season by using silicone grease-coated traps. The seasonal pattern of mite dispersal and of the number of mites on fruit showed marked and coincident peaks in early September. There were significant correlations between trap-catch and population density on both the leaf and fruit. Aculops pelekassi individuals were captured even at 80 m distance from infested citrus trees, and the mean±SD dispersal distance under the prevailing conditions was 18.0±16.3 m. These results suggest that A. pelekassi can move among orchards with different pesticide use histories. Therefore, we recommend not only using pesticides but also planting windbreaks in order to control the spread of A. pelekassi.
