中华松针蚧在迭部林区1a发生1代,主要危害油松。本研究以尼傲林场受害油松林为对象,通过设置标准地对该虫进行野外观察与室内解剖相结合的方法研究其生物学特性,目的是了解其在迭部林区的发生和为害规律;在此基础上,选用40%氧化乐果乳油和1%苦参碱(杀确爽)2种农药不同浓度进行试验防治,为大面积除治提供科学依据。
Pine needles scale Occurred in Diebu area 1a generation, the main hazard to Pinus tabulaeformis. In this study, the Pinus tabulaeformis plantation in Nicole Forest Farm was used as a research object to study the biological characteristics of the Pinus tabulaeformis plantation by field observation and indoor dissection in order to understand its occurrence and damage pattern in Diebu area. On this basis, 40% omethoate EC and 1% matrine (Kesangshuang) were used to prevent and treat the two pesticides at different concentrations to provide a scientific basis for large-scale treatment.
