The general objective of this research was to evaluate the effect of native biocidal extracts on the larval stage of Carmenta foraseminis in cocoa under laboratory conditions. The research work was carried out at the Entomology Laboratory of the Faculty of Agronomy of the National University of San Martin. Two biocidal extracts were used: Simarouba amara "Marupa" and Lonchocarpus utilis "Barbasco". To achieve the general objective, six treatments were carried out: T1 (control), T2 (10 ml of biocidal extract + 90 ml of distilled H2O - 10%), T3 (20 %) and T4 (30%), T5 (40 %) and T6 (50 %), arranged in a completely randomized design with three replicates. Four samplings were carried out for each treatment, evaluating the percentage of hatching, number of hatched larvae, percentage of attack and number of attack. An analysis of variance (ANOVA) was performed, and to determine the optimal treatment, Tukey's test of means (p ≤ 0.05) was performed. From the results obtained in the research, the ANOVA showed a significant statistical difference between treatments in the four analyses performed. Tukey's test of means (p ≤ 0.05) shows an interesting picture for the biocidal extract of "barbasco", where T6 (50 %) and T2 (10 %) turned out to be the optimal treatments. On the other hand, for the biocidal extract of "marupa", only T6 (50 %) was optimal. Finally, after evaluating the effect of the biocidal extracts, it can be concluded that the best was the biocidal extract of "marupa", since it showed a better management of hatching and percentage of larval attack, showing better results in the reduction of incidence by 73.3% and damage by 70%.
