Work was carried out with lethal doses of 3 agavaceas, Agave legrelliana, Agave fourcroydes and Agave franzosinii, and it was determined the influences of LD50 and LD90 of agavaceas on the cardiac activity reduction. As a result, it was found that A. fourcryodes has the aqueous extract influencing the most on the reduction of heart rate. LD90 of agavaceas also affects the embrionary development of eggs having between 1 and 7 days of oviposition. The greatest affectation was found among the first. A. fourcroydes and A. legrelliana, respectively, influence the most on the reduction of the amount of eggs. The number of eggs ovipositted by mollucs surviving the application of LD90 from A. franzosinii is lower, as well as the number of hatched eggs.
使用3种龙舌兰科植物（莱氏龙舌兰、剑麻和弗朗索瓦氏龙舌兰）的致死剂量进行了研究，并确定了龙舌兰科植物的半数致死剂量（LD50）和九成致死剂量（LD90）对心脏活动减弱的影响。结果发现，剑麻的水提取物对心率降低的影响最大。龙舌兰科植物的LD90也会影响产卵1至7天的卵的胚胎发育。在最初阶段发现的影响最大。剑麻和莱氏龙舌兰分别对减少卵的数量影响最大。在施加弗朗索瓦氏龙舌兰的LD90后存活的软体动物所产的卵的数量较少，孵化出的卵的数量也较少。
