本文是继「低劑量,低濃度的二二三與六六六殺滅稻田孑孓試驗」(見1954年5月號)的研究報告,由實驗結果:得出了每畝稻田用含丙種異構體的六六六乳劑0.5克,配0.5/13340的濃度,即有殺滅蚊幼效能。但本文和前發表之報告材料有其共同之缺陷,即:缺乏對低劑量,低濃度六六六殺滅蚊幼的持久性如何,每隔多久噴洒一次即可達到控制蚊蟲之孳生、繁殖等實驗報告。因此,为求得較为完整之材料,有賴於部隊衛生工作者在今後實踐中不斷總結經驗,補充材料。
This is the second report of a study on the larvae of larvae in paddy field with low dose and low concentration of 2323 and 666 (see May 1954). From the experimental results, The body of six hundred sixty-six emulsion 0.5 g, with a concentration of 0.5 / 13340, that kill mosquito young efficacy. However, this report and the previously published report have their common defects, namely, the lack of persistence of mosquito larvae at low doses and at low concentrations to control mosquito breeding and reproduction Other experimental reports. Therefore, in order to obtain a more complete material, it depends on continual summing-up of experiences and supplementary materials by military health workers in the future practice.
