摘  要：
[目的]明确桑粉虱在田间的消长动态,并筛选有效防控药剂。[方法]采用5点取样法连续2年调查桑粉虱在云南省常用栽培品种云桑2号、农桑14号和湖桑32号上的种群发生动态,并以药膜法测定了13种常用杀虫剂对桑粉虱成虫的室内毒力。[结果]桑粉虱成虫在4月中旬零星出现并开始增长,7—9月成虫数量大,3个桑树品种的桑粉虱发生量顺序为云桑2号>农桑14号>湖桑32号;13种杀虫剂对桑粉虱成虫室内毒力由高到低依次是灭多威>虫螨腈>辛硫磷>毒死蜱>阿维菌素>苦参碱>呋虫胺>吡虫啉>印楝素>吡蚜酮>多杀霉素>噻嗪酮>虫酰肼。[结论]桑粉虱主要发生期为7—9月份,更趋向于云桑2号,可选择使用灭多威、虫螨腈、辛硫磷、毒死蜱、苦参碱、印楝素等防治桑粉虱。

摘  要：
[Aims] The paper aims to screen out effective insecticides to control Pe alius mori and to identify its dynamics in the field. [Methods] The population dynamics of P. mori were investigated by five-spots sampling method in Yunnan province mulberry varieties Yunsang 2, Nongsang 14 and Husang 32 through two consecutive years, and toxicities of 13 insecticides against adults of P. mori were tested by residual film method in the laboratory. [Results] The P. mori adults sporadically appear in the middle of April and begin to grow, large number of adults in July to September, the occurred of P. mori were in the sequence of Yunsang-2> Nongsang-14> Husang-32, Toxicities of 13 insecticides against adults of P. mori were in the sequence of methomyl > chlorfenapyr > phoxim > chlorpyrifos >avermectin> matrine> dinotefuran> imidacloprid> azadirachtin> pymetrozine> spinosad> buprofezin> tebufenozide in the laboratory. [Conclusions] The occurrence of P. mori is mainly in July to September with tendency to Nongsang-32, we should give priority to methomyl, chlorfenapyr, phoxim, chlorpyrifos, matrine, azadirachtin etc. to prevention and control of P. mori in mulberry.
