| 摘要: |
| 为了有效防治山楂叶螨(Tetranychus viennensis),以喷蒸馏水为对照,配制3种不育剂(MSA、CS、MSC)对山楂叶螨进行不育效应的室内试验。MSA、CS、MSC的试验浓度(3个重复)分别是0.2%,0.5%,1.0%;0.4%,0.8%,1.2%;1倍原液,2倍原液,原液。喷不育剂后,每天对产卵、卵的孵化、交尾、寿命等观察和记载,持续3个月。结果表明,以0.8%的CS可湿性粉剂喷雾使用为最好。与对照相比,此浓度可将该叶螨的每雌产卵量(粒)、孵化率(%)及第2代雌、雄成螨数量(头)降低,分别为7.17,3.66,1.00和0.50;对照分别为73.33,84.06,32.00和70.67 |

| Abstract: |
| In order to control the leaf mite,Tetranychus viennensis (Zacher),three kinds of chemosterilants(MSA,CSⅡ and MSC) are prepared and their effects are tested in the laboratory.The tested concentrations are 0.2%,0.5%,1.0 for MSA;0.4%,0.8%,1.2% for CSⅡ;the liquid of original,and that of being diluted 1 or 2 times for MSC.It is the control that spraying distilled water on the leaf mite.After spraying of the chemosterilants on the adult mites,the oviposition,hatching,mating and life-span are recorded every day.The observation lasts for 3 months.The results show that spraying with 0.8% wettable powder chemosterilant CSⅡ gains the best sterilizing effect.The number of oviposited eggs per female adult,hatching -rate(%),and the number of female and male adults of the 2nd generation are 7.17,3.66,1.00 and 0.50,respectively,while that of the control are 73.33,84.06,32.00 and 70.67,respectively. |
