| Abstract: |
| 本文就辛硫磷水体缓释小筒的研制和现场对Aedes albopictus幼虫杀灭效果作了报道。结果表明:对于陶器、轮胎等类积水,按水体水量计算,当施药浓度同为40、6(ppm时,陶缸缓释组有效期分别为171、267~304天,轮胎缓释组为290~311、263天;陶缸药物对照组为97、101~127天、轮胎药照组为103~1(8、111天,二法差异显著。另外本文还介绍了改进的Fiske-Subbarow测总磷法,并对其中一种释药小筒的室内水中释药动态作了测定。 |

| The controlled-release tubes containing phoxim were tested for killing larvae of Aedes albopictus in water. When the concentration of phoxim in the tubes which were Put in to water in pottery vat and tyre was at 40 and 60 ppm of the body of water, the controlled-release effective time of pottery vat group was 171, 267-304 days respectively and that of the tyre group was 290-311, 263 days respectively. The effective time of pottery vat control group was 97, 101-127 days respectively and that of the tyre control group was 103-108, 111 days respectively. These methods ware remarkable different. In addition,this paper introduced a modified Fiske-Subbarow method for measurement of total phosphorus. A study on controlled-release tendency of phoxim tube in tap water in house was also reported. |
