摘　　要：对极小种群巧家五针松(Pinus squamata)7个引种地和原生地的重点分布区及周边人工种植种群的常见病虫害进行了连续5年调查,共鉴定出7种主要病害和8种主要虫害。病害分别是松梢枯病(Diplodia pinca松色二孢)、松干腐病(Cytospora pini Desm)、松落针病(Lophodermium pinastri)、松针褐枯病(Didymosporina sp.双孢霉)、松赤枯病(Pestalotia funerea);松赤落针病(Hypoderma desmazieri);松叶枯病(Truncatella sp.)。虫害分别是松褐天牛(Monochamus alternates Hope)、松纵坑切梢小蠹(Tomicus pinioperda(Linnaeus)、华山松木蠹象(Sicut pissodes)、云南松毛虫(Dendrolimus houi Lajonquiere)、松毒蛾(Dasychira axutha Collenette)、松梢螟(Dioryctria rubella Hampson)、华山松球蚜(Pineus armandixola)。阐述主要病虫害的发生情况,其中以松落针病、松梢枯病、华山松球蚜和松梢螟较为普遍,以松褐天牛、松纵坑切梢小蠹和华山松木蠹象危害最重。结合生产实际提出了综合防治措施。In this paper the common diseases and pests of minimum population of Pinus squamata located7 cultivated regions and surrounding original populations were surveyed and observed for 5 consecutive years. 7 diseases and 8 pests species of Pinus squamata were reported in this paper. The diseases were Diplodia pinca,Cytospora pini Desm,Lophodermium pinastri,Didymosporina sp,Pestalotia funerea,Hypoderma desmazieri,Truncatella sp. The pests were Monochamus alternates Hope,Tomicus pinioperda（ Linnaeus）,Sicut pissodes,Dendrolimus houi Lajonquiere,Dasychira axutha Collenette,Dioryctria rubella Hampson and Pineus armandixola. The paper elaborated the occurrence of main plant diseases and insect pests,the common disease were Lophodermium pinastri,Diplodia pinca,Pineus armandixola and Dioryctria rubella Hampson. The heaviest damage was caused by Monochamus alternates Hope,Tomicus pinioperda and Sicut pissodes. The comprehensive control measures are put forward combined with the production practice,
