Forest insect pests monitoring provides essential information for forest management against their outbreaks. Long-term monitoring data for forest insect pests have been collected by National Institute of Forest Science at national level since 1968. Forest insect pests for long-term monitoring include pine needle gall midge, black pine bast scale, fall webworm, pine moth, spotted lanternfly, etc. The monitoring data were analyzed effect of meteorological factors on the outbreaks of sporadic forest insect pests. Our results showed that meteorological factors can influenced on outbreak of forest insects. The species including Lepidoptera has more occurred when fall and winter temperature were relatively high during the period, suggesting that their outbreaks depends on mortality rate during winter diapause. In Diptera, species abundance was positively related with amount of precipitation in spring but negatively related with summer temperature. The species belong to Hymenoptera was also more abundant when spring temperature was relatively warm. These results can provide useful information for predict potential forest insect pests from climate change.
