Efecto de insecticidas neurotóxicos sobre plagas en el cultivo de maní (Arachis hipogaea L.)

The objective of the research was to evaluate the effects of commercial neurotoxic insecticides on reducing the population of common pests such as thrips and fall armyworm in peanut cultivation. The experiment was carried out in the conventional area of the Escuela Superior Politécnica Agropecuaria de Manabí Manuel Félix López. The treatments evaluated were: Spinetoram at a dose of 150 ml/hectare (T1), Spinetoram at a dose of 100 ml/ha (T2), Spinetoram at a dose of 50 ml/ha (T3), Sulfoxaflor at a dose of 150 ml/ha (T4), Sulfoxaflor at a dose of 100 ml/ha (T5), and Sulfoxaflor at a dose of 50 ml/ha (T6). The application was carried out 45 days after sowing, while the evaluations were conducted 5 days prior to application and 9 days after, taking into account the percentage of damage severity. During the evaluations, variables such as plant height, number of branches, percentage of pod set, pods per plot, grains per plot, shell weight, shelled grain weight, weight of 100 grains, and damage severity were recorded. The data were analyzed using ANOVA, and mean comparisons were performed using Tukey’s test with a significance level of 5% (p<0.05). In the analysis of variance, the treatments, including the control, showed no significant differences in either damage severity or production parameters. In conclusion, it was demonstrated that a single application of neurotoxic insecticides is not effective for the control of fall armyworm and thrips; therefore, it is recommended to increase the number of applications to achieve more efficient pest management.
