The mealybug Oracella acuta(Lobdell)Ferris,is one of the quarantine pests in China,which may cause huge damage to Pinus massoniana Lamb,P.elliottii Engelm.,P.taeda L.and other pine species.The potential geographic distribution of O.acuta were predicted using CLIMEX and ArcGIS,as well as the available biological data,documented distribution of O.acuta and meteorological data from 820 weather sites in China.The results showed that the potential geographic distribution area ranged between 3.85°N and 39.9°N,which accounts for 38.7%of the countrys total area.The areas with Pinus plants are all climate-suitable for survival of O.acuta,and therefore potentially favorable for distribution and expansion of this species.The highly suitable areas involve Taiwan,Hainan,Guizhou,Chongqing,Jiangsu,Shanghai,most parts of Guangdong,Guangxi,Yunnan,Shaanxi,Henan,Anhui,Hubei,Henan,south of Fujian,Shandong,north of Hunan,east of Zhejiang,and Sichuan.We suggest that quarantine and monitoring measures should be improved and to better prevent the spread and expansion of O.acuta in China.

螺羟吲哚是一类重要的骨架化合物,其广泛存在于天然产物和具有生物活性的分子中。此外,螺羟吲哚化合物也是合成天然生物碱和药物分子的重要中间体。由于其具有显著的生物活性,该类化合物在抗菌、抗病毒及抗癌等药物制剂中得到广泛应用。与此同时,自然界中也存在许多其他具有生物活性的骨架化合物,如吲哚、色满等。然而,尽管已经开发出许多制备螺羟吲哚化合物的方法,但合成具有双重骨架结构的螺羟吲哚化合物的方法目前报道较少
