Spatial Analysis Of Building Pest Distribution Using Land Use Data And GIS

In this study, we attempted to evaluate the likelihood of insect invasion into the site by conducting light trap surveys and analyzing the data using a geographic information system (GIS). We conducted light trap surveys using LEDs at 10 sites in the Kanto region, Japan. We extracted land use information around each site by using GIS and linked the number of insects to land use ratio by regression analysis. Based on the obtained model, we estimated the number of insects arriving and visualized it on a map. In the light trap survey, 3,015 insects were captured, and the Chironomidae family was the most abundant, which accounted for 84% of the total. For this family, a model considering a 500-meter radius around each site and two latent variables explained the insect abundance most effectively. This variable was characterized by the proportion of rice fields.
