Evaluación de la eficiencia de extracto de Ambrosia arborescens en el tratamiento y control de ectoparásitos en bovinos (Bovicola bovis)

At present, cattle farming worldwide is facing a serious problem due to ectoparasite infestation, which leads to disease, reduced production, malnutrition and death. In Ecuador, ectoparasites represent the main cause of economic losses, being the louse (Bovicola Bovis) one of the most common parasites and its proliferation is the result of deficient management techniques. The use of commercial dewormers is common, but these products have been replaced by the use of plants with antiparasitic properties such as Ambrosia arborescens (frame). The main objective of this study was to evaluate the effect of 3 different concentrations of Ambrosia arborescens extract when applied in vitro on a population sample of lice (Bovicola bovis). The experiment was carried out in the bromatology laboratory of the Pontificia Universidad Católica del Ecuador, Ibarra campus. A DCA experimental design was used, consisting of 3 treatments, a control and 3 replicates. For this purpose, samples of Ambrosia arborescens were taken in bags that were sealed and transferred to the PUCESI laboratories, where the sap was extracted using the steam distillation method, the extract was diluted in distilled water to obtain different concentrations, and samples of ectoparasites were collected and placed in Petri dishes and transferred to the laboratory for subsequent application of the Ambrosia arborescens extract. Favorable results have been obtained since in each treatment there has been an acceptable amount of parasite death and in a fairly short time interval, it has been proven that the most effective concentration was (T1) because it achieved mortality of 60% of the total sample, while the least effective treatment was T3 because it only achieved 33% mortality. The study has shown that this plant is an excellent alternative for the control of Bovicola bovis since its efficacy is high, it is easy to use and it also substitutes commercial products, thus reducing production costs in a farm.
