用野生植物杀灭钉螺是消灭血吸虫病的重要措施之一。1959年,我们曾几次到群众中收集民间有关杀虫的野生植物,前后共收集了100余种,进行了室内、现场灭螺试验,发现其中“马醉木”杀灭钉螺的效果显著,令人满意。经过反复的室内、现场灭螺试验观察,有效率均达到室内95%～100%,现场80%～92%。由于它的灭螺效果良好,产量多,价低,便于推广使用,因而我县血吸虫病流行的地区在1959年冬季已大量采集、加工和推广使用。现将植物形态、实验结果介绍于后,供各
The use of wild plants to kill snails is one of the important measures to eliminate schistosomiasis. In 1959, we collected folk insecticidal wild plants several times from the masses and collected more than 100 species before and after. We conducted indoor and on-site snail tests and found that the effect of killing snails with “horse drunk wood” was remarkable. satisfaction. After repeated indoor and field snail test, the effective rate reached 95% ~ 100% indoors and 80% ~ 92% on site. Because of its snail-killing effect, yield, low price, easy to promote the use of, so my county endemic areas of schistosomiasis in the winter of 1959 has a large number of collection, processing and promotion. Now plant morphology, experimental results introduced in the later, for each
