马尾松毛虫雌蛾具有较强释放性信息素的能力。为此,我们利用这一特性进行了马尾松毛虫发生期和发生量测报的研究。 分别应用人工合成性信息素、雌蛾活体及粗提性信息素进行诱测试验,效果良好,能在生产实践中应用。 一、人工合成性信息素的应用 马尾松毛虫人工合成信息素,系辽宁省营口市化工研究所提供,共有六种组合的诱芯,其成分分别如下: A种:2E—5.7—十二碳二稀—1—醇丙酸酯,剂量500微克/每诱芯。 B种:2E—5.7—十二碳二稀—1—醇,剂量500微克/每诱芯。 C种:醇:乙酸酯:丙酸酯的比例为4:3:3,剂量500微克/每诱芯。 D种:乙酸酯,剂量250微克/每诱芯。 E种:醇:乙酸酯:丙酸酯的比例为5:3:2,剂量500微克/每诱芯。 诱捕器采用江苏省海门三厂中学生产的三角形诱捕器,内涂上海警备区天山化工厂
Dendrolimus punctatus moth has the ability to release pheromone strongly. To this end, we use this feature to conduct a study of the occurrence and occurrence of Masson’s Dendrolimus punctatus. Synthetic pheromone, female moth and crude extract pheromone were respectively used for induction test, with good effect and application in production practice. First, the application of synthetic pheromone Masson pine caterpillars synthetic pheromones, Department of Chemical Engineering, Yingkou City, Liaoning Province, a total of six combinations of the induced core, its composition is as follows: A species: 2E-5.7- 12 carbon Dilute-1-ol propionate at a dosage of 500 micrograms per attractant. Category B: 2E-5.7-dodecan-1-ol in a dose of 500 micrograms per attractant. C: alcohol: acetate: propionate ratio of 4: 3: 3, the dose of 500 micrograms / every induced core. D species: Acetate, dose 250 μg / lure. E species: alcohol: acetate: propionate ratio of 5: 3: 2, the dose of 500 micrograms / per inducement.
