Control of Hypsipyla grandella Zeller in a commercial plantation of Cedrela odorata L., in Chiapas, Mexico

Objective: This study aimed to evaluate three control methods for H. grandella in a 2.1-year-old commercial forest plantation in Frontera Hidalgo, Chiapas, Mexico. Design/methodology/approach: Three treatments were established: T1 chemical control with the application of Cypermethrin® at a dose of 10 mL L-1 of water, T2 organic control with the application of the organic insecticide Vegex Kuneka® at a dose of 10 mL L-1 of water, and T3 silvicultural control with sanitary pruning. Results: The analysis of variance indicated that a statistical difference was found (p<0.01), where T1 and T3 showing the most favorable outcomes across the variables measured, although in general the three treatments presented low values ​​in percentage of damage (22.22%), high health status (77.78%), vigor of 84.44% and a survival rate of 94.44%. Limitations on study/implications: The site’s environmental conditions influenced the effectiveness of the applied control methods. Additionally, the biological cycle of H. grandella can vary depending on ecological conditions, complicating the establishment of a management protocol. Findings/conclusions: It is concluded that chemical, organic, and silvicultural control methods can reduce borer damage by up to 75%, and the species shows good growth development under these management strategies.
