Hard ticks are a problem of great importance in the national livestock industry due to their capacity to be vectors of diseases that affect the productivity of animals and humans, becoming an arthropod of veterinary-medical importance. The methods used for their control have not been efficient; therefore, different integrated control alternatives have become crucial to mitigate their population growth. Products such as calcium polysulfide have shown to be an effective alternative in controlling mite populations. The present study was carried out at the Center for Research and Breeding of Natural Enemies of the University of Caldas using nymphs of Amblyomma cajennense, arranged in Petri dishes and sprayed with an average volume of calcium polysulfide of 1.3ml. From there, the lethal concentration of calcium polysulfide at 31.5°B, on the individuals of this species was determined. The evaluations were carried out at 24, 48 and 96h after application, finding, by Probit analysis, Cl50 of 1.05% and Cl95 of 1.35% concentration of the product, which indicates that this compound has the potential to be used in the integrated management plan of A. cajennense.
