茶卷叶蛾在苏南一年发生四代,以幼虫将芽叶卷缀咀食,危害较大,如不及时进行防治,连成叶和老叶都将遭受危害,影响茶叶产量和品质。茶树是叶用植物,采收的幼嫩芽叶不经洗涤,直接加工成干茶,为了探索新的防治技术,尽量少用化学农药,减轻污染,我们在1982和1983两年中,采用茶卷叶蛾性诱化合物与20瓦黑光灯进行了诱蛾对比试验,以了解其诱蛾效率和使用方法。现将试验情况小结如下: 一、材料与方法茶卷叶蛾性诱化合物,是由江苏省昆虫激素研究所合成提供,为C9—12AC,C11—14AC,配比是1:10,剂量500微克。
Tea leaf roller occurs four generations a year in southern Jiangsu, larvae shoot buds Tsui food, more harmful, if not timely prevention and control, even into the leaves and the old leaves will be harmed, affecting the yield and quality of tea. Tea tree is a leaf plant, young shoots harvested without washing the leaves, directly processed into dry tea, in order to explore new prevention and control technology, minimize the use of chemical pesticides, reduce pollution, we in 1982 and 1983 two years, the use of tea The leaf moth sexual attractant and 20-watt black light were compared with those of the moth to understand its moth’s efficiency and its application method. Now the test conditions are summarized as follows: First, materials and methods of tea leaf roller moth sex attractant compounds, synthesized by the Jiangsu Institute of Entomology hormone, C9-12AC, C11-14AC, the ratio is 1:10, the dose of 500 micrograms.
