我区自70年代中期开始引种国外松(湿地松和火炬松),并相继建立了种子园,近几年来已陆续结实,但发现不少球果遭受虫害,种子产量和质量受到严重影响,我们于1991年在樟树市试验林场,高安县荷岭林场对国外松球果害虫进行了初步调查,现将调查结果简报如下。 Since the mid 70s of last year, our district has introduced foreign pine (Pinus elliottii and Pinus taeda) and established seed orchard in succession. In recent years, it has been gradually strengthened. However, we found that many cones suffer pests and the yield and quality of seeds are seriously affected. In 1991 in Zhangshu City Experimental Forest Farm, Gao Anxian Hailing Forest Foreign pine cone pests conducted a preliminary survey, the survey results are as follows.
