The objective of this research was to evaluate the toxicity of spinetoram and matrine on the developmental states of Chrysoperla externa and Ceraeochrysa cincta. Toxicological tests were carried out by the method of immersion, residual contact and ingestion with the chemical products: spinetoram (0.375 ml/500 ml and 0.125 ml/500 ml) and matrine (0.5 ml/500 ml and 1.5 ml/500 ml). The data obtained were analyzed with the Kruskal-Wallis test with a significance level of p≤0.05. The immersion tests of eggs and pupae of C. externa and C. cincta showed statistically similar values to the control (p≤0.05). By residual contact, the highest percentages of mortality in adults of both species were obtained, which ranged between 60.50-80.00 % with the concentrations of spinetoram. In ingestion tests, adults of C. externa and C. cincta were more susceptible to both chemicals in relation to larval status. Finally, according to the toxicological cataloging of the IOBC, the chemicals were harmless in eggs and pupae of both species by immersion tests. By residual contact, the maximum concentration of spinetoram was slightly harmful in larvae of the first and second stage of C. externa, however, the maximum and minimum concentration of the product were slightly harmful for adults of C. externa and moderately harmful and slightly harmful in C. cincta adults, respectively. By ingestion tests, both concentrations of spinetoram were slightly harmful in chrysopid adults, while only the maximum concentration of matrine was slightly harmful in adults of C. cincta.
