龟蜡蚧 Ceroplastes Japonicus Green,又名龟甲蜡蚧、日本蜡蚧,在我省各地均有发生,危害枣树、柿树、悬铃木、大叶黄杨等树种,当气候条件适宜或用药防治不当时发展很快,特别是在我省多数枣区对枣树的危害性很大,往往造成大枣大幅度减产。龟蜡蚧在自然界里有许多天敌,其中寄宅蜂类在其种群的自然控制中起着相当重要的作用。为了保护、利用天敌防治龟蜡蚧,并为开展综合防治提供依据,作者近几年来在指导学生野外实习和科学考察中,对这类有益生物资源进行了调 Ceroplastes Japonicus Green, also known as turtle wax scale, Japan wax scale, occurred in all parts of our province, endangering jujube, persimmon, Platycodon grandiflorum, Euonymus japonicus and other tree species, when the climatic conditions are appropriate or the development of inappropriate medication control Soon, especially in the majority of jujube areas in our province jujube tree is very harmful, often resulting in a substantial cut in jujube. Turtle scale has many natural enemies in nature, of which the sentinel bees play a very important role in the natural control of their populations. In order to protect and utilize natural enemies to prevent and control turtles larvae, and to provide a basis for comprehensive prevention and control, the author has conducted such studies in recent years to guide students in field internships and scientific expeditions
