Qiao Wang has made outstanding contributions to insect science and plant protection. His internationally renowned research on insect behaviour and biological control has advanced understanding of sexual selection, cue-induced reproductive investment, and parasitoid-host interactions, providing novel knowledge for development of behaviour-based and environmentally friendly pest management measures. Wang is a world-leading authority of longicorn beetles, reflected in his book Cerambycidae of the World and other works, facilitating better detection and control of longicorn pests globally. His discovery and introduction of parasitoids into the USA have successfully controlled an invasive longicorn pest there. He has also developed expert documents and identification tools on quarantine longicorns for the Ministry of Primary Industries. His expertise has made major contributions to a quarantine pest regulation for the European Union and provided scientific evidence for a World Trade Organization recommendation on international market access. Furthermore, he has been appointed to various national and international expert panels and committees. His research excellence has been ranked world-class several times by the New Zealand Tertiary Education Commission and recognised by the Entomological Society of America Distinguished Scientist Award.
