旨在探讨蛀干害虫物理防治技术的新途径。蛀干害虫历来是城市园林绿化和林业树木破坏性最大,防治最困难的害虫之一,试验表明,微波对刺角天牛等多种蛀干害虫能产生很强的热效应,对幼虫的致死温度≥50℃,而树木对微波产生的热效应,其承受高温的安全阀限值高于天牛5～10℃;波谱分析及试验证明,微波直接杀虫的最佳频率为2450MHz而兼具穿透性能良好又能杀死蛀干害虫的最佳频率915则是MHz。频率确定后,功率的大小与害虫的致死速度成正相关性,同时,考虑到寄主种类、树龄、胸径、含水量、生长势等各方面因子的变化、差异和制约,功率以选用1～5KW连续可调为宜。
Aiming to explore new ways of physical control of stem borers. Drilling pests has always been one of the most devastating pests in urban landscaping and forestry trees. Experiments show that microwaves can exert a strong thermal effect on many borers such as Horned Beetle, and the lethal temperature to larvae ≥50 ℃, while the trees on the heat generated by the microwave, the high temperature limit of its safety valve is higher than the day cow 5 ~ 10 ℃; spectrum analysis and testing proved that the best microwave direct insecticide frequency of 2450MHz and both through The best frequency for good performance and for killing pests is 915 MHz. After the frequency is determined, the power has a positive correlation with the lethal speed of pests. At the same time, taking into account the changes, differences and constraints of host species, age, DBH, water content, growth potential and other factors, Adjustable as appropriate.
