| Abstract: | From January 2001 to December 2004, the investigation on the species of insect pests and diseases in Torreya grandis Merrillii was conducted and integrated control technologies of the main insect pests and diseases were studied in Zhuji,
Shaoxin, Shenzhou, Dongyang, and Jiande counties of Zhejiang Province. Via field survey, a system of regular observations,
55 species of insect pests belonging to 9 orders and 29 families, and 4 species of diseases were recorded. Among them, Lepteucosma torreyae and Macrolygus torreyae were found to be new species. The biological characteristics of the major insect pests and diseases, such as Rhyncaphytoptus abiesis, Helicobasidium compacum, Erwinia carotovora, Chlorella sp., Macrolygus torreyae, and Lepteucosma torreyae, were primarily recorded, and their outbreaks and epidemics were researched. The forecasting method for Lepteucosma torreyae was established. Based on strengthening cultivation and management, integrated control measures were put forward including
physical, biologic and chemical methods. Medications with higher effect and lower toxicity were screened by comparing the
effect of different pesticide treatments.
