Mirex, a hydrocarbon, was mixed with corn oil and injected into chick embryos to test its toxic effect. At a concentration of 0 05 mg mirex/egg, embryo mortality was 40%, at 0.5 mg/egg, mortality was 49%, and at 5.0 mg/egg, mortality reached 81%. Mortality of control eggs injected with corn oil alone was 36%. The body weights of newly hatched chickens and of 4-week-old chicks were not different from those of controls. No clinical signs of disease were seen during the 4 weeks of observation. However, liver weights were increased at all 3 dosages when the birds were killed at 4 weeks, but spleen and bursal weights were not. The results support the decision to discontinue the use of mirex as a pesticide in the environment for controlling the fire ant (Solenopsis sp.) until a better means of presenting it can be found.
灭蚁灵（一种碳氢化合物）与玉米油混合后注射到鸡胚中，以测试其毒性作用。当灭蚁灵浓度为0.05毫克/枚鸡蛋时，胚胎死亡率为40%；浓度为0.5毫克/枚鸡蛋时，死亡率为49%；浓度为5.0毫克/枚鸡蛋时，死亡率高达81%。仅注射玉米油的对照鸡蛋死亡率为36%。新孵化出的小鸡以及4周龄小鸡的体重与对照组无异。在4周的观察期内未发现任何疾病的临床症状。然而，当这些鸡在4周龄时被处死后发现，所有三个剂量组的鸡肝脏重量均增加，但脾脏和法氏囊重量未增加。这些结果支持了如下决定：在找到更好的使用方法之前，停止在环境中使用灭蚁灵作为控制火蚁（红火蚁属）的杀虫剂。
