1999-2001年，在永靖县羊血液原虫病流行区进行了最佳灭蜱药物筛选试验和抗原虫药物预防、治疗羊泰勒虫病效果对比观察试验。结果表明：最佳灭蜱药物是灭蜱灵，平均有效期为55d，灭蜱预防后的发病率可降低到3.07％；虫克星是理想的防治辅助用药；贝尼尔脂质体和贝尼尔与蜱灵配合应用后，预防保护期达54d、45d，用药后60d发病率为2％、2.27％，比对照组49.46％降低47.46、47.19个百分点，预防效果明显；贝尼尔脂质体和焦虫净的治愈率为95％、87.85％，比对照组35.71％提高59.29、52.14个百分点，是首选治疗药物。     

仲丁灵乳油芽前土壤处理对草坪质量的影响

就芽前除草的安全用药方面做了研究,通过白三叶、早熟禾、高羊茅三种不同草种的草坪做试验对比,认为48%仲丁灵乳油是一种很好的芽前除草剂,而不同浓度的仲丁灵乳油对不同草坪草种会产生不同的影响,48%仲丁灵乳油500倍液做芽前除草经济有效。高浓度的仲丁灵乳油对禾本科草坪草种的发芽有明显的抑制作用,而对白三叶的种子萌发影响小。     

Factors affecting Eurasian lynx kill rates on semi-domestic reindeer in northern Scandinavia: Can ecological research contribute to the development of a fair compensation system?

Semi-domestic reindeer (Rangifer tarandus) are the main prey for lynx (Lynx lynx) in northern Scandinavia. This causes large, but poorly documented, losses of reindeer. Although the compensation schemes differ between Norway and Sweden, there is a legal requirement in both Scandinavian countries that losses of semi-domestic reindeer to large carnivores should be fully compensated. The current level of compensation payment is based on limited data on lynx kill rates on reindeer. The main goal of this study was to quantify lynx kill rates on reindeer across a range of ecological conditions in northern Scandinavia. A total of 35 lynx were monitored during 3667 days. All lynx individuals killed reindeer. However, we observed a high variation in individual kill rates. Kill rates were strongly affected by sex and social status (i.e. females with and without kittens), as well as season and reindeer availability. The highest kill rates were observed in summer for male lynx, and the lowest were observed during winter for solitary lynx at low reindeer density. In summer, several female lynx switched completely to small prey species even at high densities of reindeer. The present political goals for lynx conservation in Scandinavia require that lynx occur in the reindeer husbandry area where reindeer are the only suitable ungulate prey available. Accordingly, it is therefore impossible to have the total prevention of depredation as a management goal. Rather depredation levels must be limited such that they are considered acceptable, and fair compensation payments should be paid. Our study is the first empirical quantification of the magnitude of lynx depredation on semi-domestic reindeer. This is an important step necessary to enable the setting of fair compensation levels and will hopefully lead to a reduction in conflict level concerning the potential impacts that lynx have on reindeer.

盐度对寄主暗纹东方鲀(Takifugu obscurus)存活影响及其对车轮虫的杀灭作用

为防治河鲀车轮虫病,分别设置0、2.5、5.0、7.5、10.0、12.5、15.0、17.5、20.0、25.0、30.0、35.0和40.0共13个盐度梯度,对暗纹东方鲀进行了浸浴实验。结果显示,盐度为15以下,对暗纹东方鲀的存活没有影响;盐度为0、2.5、5.0时,4 d内车轮虫的数量没有减少反而有增加趋势;盐度7.5作用4 d,盐度10.0作用3.5 d,盐度12.5作用3 d,杀虫率可达95%以上;盐度15.0作用32 h,盐度17.5作用24 h,盐度20.0作用10 h,盐度25.0作用4 h,盐度30.0作用1.5 h,盐度35.0作用1 h,盐度40.0作用0.5 h,对车轮虫的杀虫率均可达100%。应用SPSS软件,对杀虫盐度和时间进行拟合曲线方程分析,其数学模型为对数曲线方程y=34.19-5.55lnx。另外,车轮虫在暗纹东方鲀体表的复活试验显示,用提高盐度的方法杀灭暗纹东方鲀体表车轮虫后,再恢复到正常养殖盐度5.0的情况下,暗纹东方鲀的体表车轮虫病不再复发,说明盐度7.5以上能治疗暗纹东方鲀的车轮虫病。结合提高盐度治疗暗纹东方鲀车轮虫病的生产性试验结果,建议以盐度为7.5–15.0作为治疗暗纹东方鲀体表车轮虫的适宜盐度。
