不同溶剂及浓度对圆盾蚡蜡质溶解性的对比试验

核桃园里的圆盾蚡危害较大,其防治效果直接影响着核桃树木生长及产量 。为了从根本上解决此类害虫防治难 题,筛选出能快速溶解其表面蜡质的成分,使杀虫药轻松进入其体内,提升核桃病虫害防治能力 。本次试验采用不同溶剂 溶解圆盾蚡幼虫蜡质,筛选出高效溶解圆盾蚡蜡质的溶剂及其浓度 。结果表明,含有钠离子的碱性物质对圆盾蚡幼虫的蜡 质溶解效果较好,在圆盾蚡病虫害防治中,加入含有钠离子的碱性物质,有助于溶解蜡质,可达到更好的病虫防治效果。

Evaluation of Forest Stand QualityBased on Remote Sensing Data

Aspidiolini in Walnut Orchard seriously affect its growth and production . To control these pests fundamental- ly, screen out ingredients that quickly dissolve the wax on their surfaces , allowing pesticides to enter their bodies easily. In this experiment, different solvents were used to dissolve the larval wax of scale insect, and the solvents and their concentra- tions were selected to rapidly dissolve the wax of scale insect. The results showed that the alkalinity containing sodium ions was more effective in dissolving the waxy matter of the larvae Aspidiotini. The addition of the alkalinity containing sodium ions was helpful in dissolving the waxy matter , the better effect of pest control can be achieved.
