摘要：
Potato is an important food crop. The Colorado potato beetle (CPB) is its key pest. CPBs are now resistant to several chemical pesticides, making their control more difficult. The predatory insect, Arma chinensis, is a natural enemy of other plant pests. We studied the predation of adult A. chinensis on CPB eggs and young larvae under indoor controlled conditions and its control of CPB in cages under outdoor conditions. Adult A. chinensis effectively reduces CPB egg and larva populations, and its predatory functional response aligns with Holling's Type II model. A. chinensis adults released within outdoor cages reduced CPB populations. Based on the predation behavior of the adults of A. chinensis to CPB eggs and young larvae, A. chinensis is an efficient and potential predator.
