Laboratory observations were made on the effects of two metal salts, FeCl3 and CuCl2, on the life of a terrestrial predatory snail, Zonitoides nitidus. These effects were studied, either by direct dipping of predators in the salts with the study of their predation on living lymnaeid snails during the 10 days after dipping, or by exposure of intoxicated, living snails to predators during 28 days. The number of eaten preys and the number of egg laids steadily decreased in the Z. nitidus groups dipped in the toxics during more and more long times. The same results were observed in the Z. nitidus groups eating intoxicated preys after day 7 of experiment. More toxic effects were obtained in all the egg laids of predators in contact with CuCl2 than with FeCl3. The significance of these results is discussed in relation with the joint and alternate control of L. truncatula by chemical and biological means.
对两种金属盐（FeCl₃和CuCl₂）对陆生捕食性蜗牛Zonitoides nitidus寿命的影响进行了实验室观察。这些影响的研究方法有两种，一种是将捕食者直接浸入盐中，然后在浸入后的10天内研究它们对活的椎实螺的捕食情况；另一种是在28天内将中毒的活蜗牛暴露于捕食者面前。在越来越长时间浸入有毒物质的Z. nitidus组中，被捕食猎物的数量和产卵数量稳步下降。在实验第7天后食用中毒猎物的Z. nitidus组中也观察到了相同的结果。与FeCl₃相比，与CuCl₂接触的所有捕食者的卵产生的毒性作用更大。结合化学和生物学手段对截形苜蓿进行联合和交替控制，讨论了这些结果的意义。
