The impact of various kinds of insect pests on a blueberry orchard in Dandong was investigated through field studies and indoor trials in 2008—2009. Twenty-two species of pests from 5 orders and 13 families were recorded. Coleopteran and Lepidopteran pests were the most common,mainly damaging the roots,leaves, flowers and fruits of blueberry thereby seriously affecting plant growth,development and fruit quality.
