Table 3. Monthly number of olive psylla/tree recorded on infested olive in Ain fares and in Oued taria during 2019/2020.The cumulative number in the same row with different letters significantly differs at P–value ≤ 0.05 (tests for significant differences among all pairs using x2–test; NS, not significant at P–value ≥ 0.05).

Tabla 3. Número mensual de psílidos del olivo/árbol registrado en los olivos infestados en Ain fares y en Oued taria en 2019/2010. El número acumulado en la misma fila con distintas letras difiere significativamente en valores de P ≤ 0.05 (tests para diferencias significativas entre todos los pares usando el test x2; NS, no significativo en valores de P ≥ 0.05).
