武汉市农田林网白蚁生存环境与防治技术研究初探

白蚁是危害武汉市农田林网的主要害虫之一,对全市立木、农作物、建筑和木材谷物等造成很大损失。本研究调查了武汉市主要农田林网地区白蚁的种类、生物学特性及活动生存环境,并分析了种群与土壤之间的关系。结果显示项目研究地农田林网树木白蚁主要为黑翅土白蚁,喜欢生活在潮湿的土壤中。在粘壤土中,主巢入土深度在150 cm以内的占总数80.2%。通过毒饵诱杀法和药物阻隔法,市售的三种药剂均对黑翅土白蚁具有较好的防治效果,平均防治效果达到80.0%以上。

Termite Living Environment and Controlling Technique of Farmland Shelterbelt in Wuhan

Abstract: Termite is a main pest damaged agroforestry in Wuhan, it had a great damage to stumpages, crops, buildings and wood grains. Surveyed the main farmland shelterbelt termite species, biological characteristics and living environment in Wuhan, analyzed the correlation of the species with the soil. The results showed that farmland shelterbelt main termite is Odontotermes formosamus, preferred to live in moist soil. In the clay loam, the main nest buried within 150 cm accounted for 80.2%. The three commercially available medicines had a good controlling effect, the average effect reached above 80.0%.
