Resumo: | This work was carried out in canton Salitre, province of Guayas, for the purpose of evaluating the defoliations by Cerotoma fascialis by means of two sampling methods in two varieties of soy (Glycine max). The used methodology was a completely random block design (CRBD) with 2x2 factorial arrangement where Factor A represented the varieties: INIAP 308 and FAENA; and Factor B represented the types of sampling: Systematic and Random, assigned in 4 treatments and 5 repetitions: T1 (INIAP 308*systematic sampling), T2 (INIAP 308*random sampling), T3 (FAENA*systematic sampling), T4 (FAENA*random sampling). For the comparison of the means between the treatments, the Tukey multiple-range test was implemented at 5% of probability. Results: Random sampling was the lowest accurate method for counting defoliations reflecting the lowest mean with 11.27 perforations; on the other hand, the systematic sampling as more accurate and significant obtaining the highest average with 13.55 perforations. Drilling count, T4 (FAENA*random sampling) presented lower average with 8.57 perforations; on the contrary, T1 (INIAP 308*systematic sampling) was significant with a higher average of 17.90 perforations. These results affect the percentage of affectation where the lowest average had T4 (FAENA*random sampling) with 30.46%; whereas, the highest average was t1 (INIAP 308*systematic sampling) with 56.94% of affectation. The FAENA variety had lower defoliation intensity with 8.88 perforations; however, the INIAP 308 variety was significant, presenting susceptibility with 15.93 perforations. |

Este trabajo se lo realizó en el cantón Salitre, provincia del Guayas, con el propósito de evaluar las defoliaciones por Cerotoma fascialis mediante dos métodos de muestreos en dos variedades de soya (Glycine max). La metodología que se empleó fue un diseño de bloques completamente al azar (DBCA) con arreglo factorial 2x2 donde Factor A representó las variedades: INIAP 308 y FAENA; y Factor B representó los tipos de muestreos: Sistemático y Aleatorio, asignado en 4 tratamientos y 5 repeticiones: T1 (INIAP 308*muestreo sistemático), T2 (INIAP 308*muestreo aleatorio), T3 (FAENA*muestreo sistemático), T4 (FAENA*muestreo aleatorio). Para la comparación de las medias entre los tratamientos se implementó la prueba de rangos múltiples de Tukey al 5% de probabilidad. Resultados: El muestreo aleatorio fue el método menor preciso para el conteo de defoliaciones reflejando el menor promedio con 11.27 perforaciones; por otro lado, el muestreo sistemático fue más preciso y significante obteniendo el mayor promedio con 13.55 perforaciones. Conteo de perforaciones, T4 (FAENA*muestreo aleatorio) presentó menor promedio con 8.57 perforaciones; al contrario, T1 (INIAP 308*muestreo sistemático) fue significante con mayor promedio de 17.90 perforaciones. Estos resultados inciden en el porcentaje de afectación donde el menor promedio lo tuvo T4 (FAENA*muestro aleatorio) con 30.46%; mientras que, el mayor promedio fue T1 (INIAP 308*muestreo sistemático) con 56.94% de afectación. La variedad FAENA tuvo menor intensidad de defoliación con 8.88 perforaciones; sin embargo, la variedad INIAP 308 fue significante presentando susceptibilidad con 15.93 perforaciones.
