    Plant extracts obtained from different plant substances after various processes are an alternative for pest control. The purpose of the present investigation was to evaluate the effect of plant extracts based on the cannabis plant, for the control of Bactericera cockerelli, under laboratory conditions, the final purpose was to record, which of the cannabis extracts demonstrated the better control of the pest and have an alternative with less impact on the environment and people. Within this research work, a completely randomized experimental design was used with a factorial arrangement (2*2) plus an additional 1. With a total of 5 treatments in 6 repetitions to then proceed with the extraction techniques to obtain our Live resin extracts at 50% and 75% and Cannabis essential oil at 50% and 75%, obtained from the recently harvested cannabis plant and passed through a curing and drying process and then proceed to apply them with their respective witness. The test was carried out under the appropriate conditions of humidity and temperature, then Bactericera cockerelli was introduced, and the population of 15 individuals distributed in each experimental unit, subsequently the application of the extracts was carried out with a spray bottle, the data were taken after 3 hours of the application, so in this way every 3 hours, the data was taken for 18 hours, the dead individuals were counted in a period of 15 minutes, the record was made in a field book, so later tabulate the data using the infostat program, for obtaining the ANOVA analysis and the Tukey test at 5% and thus obtain the following results. It can be seen in the evaluations that (Live Cannabis Resin 75%), (Live Cannabis Resin 50%), had the best control, followed by (Cannabis Essential Oil 75%).
