| 中文摘要: |
| 鉴定危害香榧的4种蚧虫,比较不同蚧虫的为害率,测定不同的环境友好型药剂的田间防治效果。结果表明这4种蚧虫为柳杉圆盾蚧Aspidiotus cryptomeriae Kuwana和3种在香榧上新发生为害的蚧虫,松细蛎盾蚧Lepidosaphes piniphilus Borchsenius、日本单蜕盾蚧Fiorinia japonica Kuwana和为褐软蚧Coccus hesperidum L.,松细蛎盾蚧的为害率最高。33%螺虫.噻嗪酮3000倍液、22.4%螺虫乙酯3000倍液、50%噻嗪酮3000倍液和99%绿颖矿物油200倍液均具有防效,前两种药剂防效较好。本研究可作为香榧蚧虫的识别和防治的提供有效信息。 |
| 英文摘要: |
| Four kinds of coccids harming Torreya grandis ‘merrillii’ were identified, the damage rates of different coccids were compared, and the field control efficiency of different environmentally friendly insecticides were determined. The results showed that the four coccids were Aspidiotus cryptomeriae Kuwana, and three newly occurring pest species on T. grandis, Lepidosaphes Piniphilus Borchsenius, Fiorinia japonica Kuwana and Coccus hesperidum L. L. piniphilus Borchsenius had the highest damage rate. The field control efficiency of 33% spirotetramat.buprofezin (3000-fold diluent), 22.4% spirotetramat (3000-fold diluent), 50% buprofezin (3000-fold diluent) and 99% SK petroleum oil (200-fold diluent) was observed, and the first two agents have better control effect. This study can provide effective information for the identification and coccids control of T. grandis. |
