A Basic Study on the Establishment of Prediction Maps for Fruit Damage by Stink Bug via Satellite Data based on Cedar and Cypress Forest Distribution

Abstract

Fruit damage by stink bugs on orchards began to occur nationwide since the 1970's. In Wakayama Prefecture, persimmons and peaches have been hurt the most. In this study, a map was made for illustrating the possibility for damage at the basin of Kinokawa River. First, land cover was classified on a map based on satellite images. The cedar and cypress forest were classified and paired with the land cover map layer. In addition, maps for predicting damage levels were established based on the rule that orchards within a shorter distance from cedar and cypress forest have high relationship with greater damage by stink bug.
