This work was done to determine the toxicity and bioactivity of four organic insecticides and ultimately find answers about their toxic potential. Thus, farmers will be able to take the necessary precautions when using them. This investigation was performed in the Laboratory of Biology of the Eastern University Center (Chiquimula) at the University of San Carlos, Guatemala. In order to determine the acute toxicity and bioactivity of the organic insecticides ANONAZO, BOX, AJORIN, and NARCISO, five doses were used in albino mice and three concentrations in nauplii of brine shrimp (Artemia salina). The finney basic program was used for calculating the average lethal dose (DL50) and the average lethal concentration (CL50). The results showed that in albino mice, ANONAZO had a DL50=707.10 mg/kg of weight which is classified as slightly toxic according to the Williams table. However, a tendency towards being moderately toxic was also present. CAJA had a DL50=>5000 mg/kg of weight classifying it as practically non-toxic. AJORIN had a DL50=4530 mg/kg of weight corresponding to the slightly toxic classification. In addition, a tendency towards being practically non-toxic was present. NARCISO had a DL50=158.11 mg/kg of weight corresponding to the moderately toxic classification but on the border of highly toxic. In regards to bioactivity in nauplii of brine shrimp: Anonazo, Ajorin, and Narciso had values less than 1000 ppm, which indicates that they have bioactivity. Caja showed no bioactivity.
