| Abstract: |
| 本文就辛硫磷水体缓释小筒的研制与户外对Aedes Albopictus幼虫防制效果作了初步观察,结果表明:辛疏磷采用盛器集中贮药,底孔释药膜释药的方式,筒内填盛河砂、泥纸载体的,残效期可延长到2~5倍;筒内直接贮盛药液的,残效期可延长到7~8倍,并且当按水体水量计算,筒内盛装药量达60ppm时,后者有效期可达七个月之久。此外,本文还对缓释小筒常见的药物滞留和可供利用度作了查究。 |
| English Abstract: |
| The controlled-release tubes containing phoxim were tested for killing larvae of Aedes albopict us in outdoor bodies of water. Residual efficacy could be prolonged 2~5 times when phoxim, mixed with river sand or waste paper puip, was put in the tubes, and released through the membrane at the bottom holes.It could be prolonged even 7~8 times when phoxim alone was put in the tubes; when the dosage contained in the tubes was at 60 ppm of the bodies of water, residual efficacy could last as long as 7 months. Here is a brief explanation of how to make the tubes.Moreover, some studx has been done on the usual residue of insecticides and its utilisibility in the tubes. |
