| 摘 要： | 广东桑园害螨发现5种,侧多食跗线螨、菜叶螨是桑园的主要害螨。本文首次报导了受侧多食跗线螨为害后,桑叶的含水量、蛋白质、氨基酸总量的变化。 从采收方式及化学防治研究了桑园两种害螨的控制,打顶和正常采叶对两种害螨田间种群密度有不同的影响。以虫口减退率及种群趋势指数(Ⅰ)值,评价几种农药对侧多食跗线螨的控制作用,结果表明,石硫合剂和克螨特对家蚕低毒而对害螨控制效果良好,可以在桑园中使用。

| Abstract: | There have been found 5 species of injurious mites in the mulberry plantations of Guangdong Province, (?) (Banks) and (?) Andre being the major onsis The changes in the water, ptotein and total amino adds content in the mulberry leaves attacked by (?) lation (Banks) are first reported in this paper. The absolute levels of the above-mentioned substances of the attacked leaves were greatly decreased, and thus the sericultural productivity was seriously affected. As to the studies on the control of both of the injurious mites in mulberry plantations in terms of harvesting methods and chemical measures, the top-clipping harvesting methods and the ordinary leaf-harvesting method had a different effect on the population density of the mites in the field;in respect to the depression ratio of the population and population trend index (I) value,in the assessment of the efficacy of several kinds of insecticides upon (?) (Banks), the results showed that lime sulphur mixture and Proparsits wen both effective in controlling the mites with low toodcity so the silkworms; they can be popularized in mulberry plantations. |
