Therefore, this study aimed to test the use of yellow card traps around the crop to manage insect vectors of viruses and test the best density of traps/tomato plants. Yellow card traps were placed on the border of the crop plot to capture adult insect vectors. Density of trap/tomato plant was assessed in 10 blocks at the following levels： 1/25; 1/50; 1/75; 1/100; 1/125; 1/150. The monitoring was carded out in 1% of the crop during 60 days in 2011 and 2012 crop. The evaluated systems were Conventional and Phytosanitary Pest Management （PPM）. During 2011 season the Conventional system received 14 insecticide applications whereas only 6 insecticide applications were made on the PPM, representing a reduction of 133%. In 2012, the crop under Conventional system was subjected to 15 applications of insecticides, over 8 on PPM, with a reduction of 87.5%. The PPM allowed a 90% reduction in application cost for this insects, obtaining a reduction of R$1,345.00/ha. The highest density was 60 plants/trap. We can conclude that the yellow card traps in tomato crop decreased infestations of insect vectors of viruses.展开更多
目的:对比中英两国药品不良反应(adverse drug reaction,ADR)监测制度的不同,加强和完善我国ADR监测体系的建设。方法:从监测主管机构、监管范围以及报告原则等方面系统比较分析中英两国之间的ADR监测制度。结果:英国实行中央集中管理AD...目的:对比中英两国药品不良反应(adverse drug reaction,ADR)监测制度的不同,加强和完善我国ADR监测体系的建设。方法:从监测主管机构、监管范围以及报告原则等方面系统比较分析中英两国之间的ADR监测制度。结果:英国实行中央集中管理ADR监测体系,而中国采用国家、省级以及省级以下的三级ADR监测体系;英国以黑色倒三角符号标志重点监测药物,新药监测期为2年,中国对新药和进口药5年内进行重点监测;英国根据不同报告主体设计表格,而中国采用统一模式设计表格。结论:应积极学习和借鉴英国ADR监测制度的优点,进而完善我国ADR监测制度。展开更多

文摘[Objective] To evaluate the control effect of yellow sticky cards and sex pheromone on Plutella xylostella and Liriomyza spp.,which can provide reference for large area extension of the technique.[Method] The integrated assessment of trapping efficiency of colored sticky cards and sex pheromone on Liriomyza spp.and Plutella xylostella was conducted by field surveys and structured interview in Tonghai County,Yunnan Province,China.[Result] The results showed that yellow sticky cards and sex pheromone have strong power of trapping Liriomyza spp.and Plutella xylostella（3 414±720 and（219±157） head/piece,respectively）;the control cost by the usage of pesticide is the highest,（10 099.5±2 752.5） yuan/hm^2,yellow sticky cards and sex pheromone takes the second place,（1 125.0±465.0） yuan/hm^2,the control cost by the usage of yellow sticky cards is the lowest,（450.0 ±186.0）yuan/hm^2.Without the usage of yellow sticky cards and sex pheromone,pesticide application times and costs are（15.0±2.7） times and（12 070.5±2 136.0） yuan/hm^2;combined with usage of yellow sticky cards and sex pheromone,pesticide application times and costs reduce by 5.7 times and 4 618.5 yuan/hm^2.The ratio of trapped beneficial insects and target pests was 1 ∶1 131,which showed that the negative effect of yellow sticky cards and sex pheromone on the non-target insects was very limited.[Conclusion] The trapping approach has become popular among all the local farmers.Looking at the above factors,the trapping technology has strong application prospect and promotion value in pest control field.
