| 摘 要： | 以4年生黑宝石李Prunus salicina'Friar'为试材,采取不同时期喷洒20%灭扫利乳油2 000倍液防治李实蜂Hoplocampa ninutominuto,评价不同处理的防治效果.2 a的试验结果表明,在花前(花蕾处于露色期、个别单花开放)和花后(花基本落完时)各喷1次,可使黑宝石李受李实蜂危害而造成的虫果率下降到10.9%和10.6%,是防治李实蜂的最佳时期,花前用药可以防止成虫产卵,花后喷药防止幼虫蛀果.在生产上以物候期为指标指导李实蜂防治更具有实际意义.表1参9 |

| Abstract: | In the experiment on Prunus salicina 'Friar', the influence of the time of applying pesticid on the prevention and control of Hoplocampa ninutominuto was studied. The results of two-year research showed that applying pesticide once before the blossom and after the blossom respectively could decrease the percentage of moth-eaten fruits to 10.9% and 10.6%. Therefore, these two phases were optimum periods to apply pesticide to prevent and control H. ninutominuto. Applying pesticide before the blossom could stop the laying of imagoes and applying after the blossom could prevent fruit eating by larvae. Using phenological phase as an index to prevent and control H. ninutominuto was practical.Ch,1 tab.9 ref.] |
