Resumen:
Hylesinus mexicanus, recently listed as one of the pests in the family Scolytidae attacking olives, is currently present only in Ixmiquilpan, Hidalgo, México. To know its impact in this crop we evaluated its monthly incidence, intensity of damage, and population dynamics in nine orchards of this region. This insect affected between 0-39% of the branches (average of 18%) with an intensity of 0.45 and 7.42 holes per branch, affecting 4.9% of the trees. Adults were most abundant between December and April, a time that coincides with the dry season; less abundance was observed between May and August and complete absence of the beetle during September and October. Some of the main factors of this pattern could be drought and pruning debris left in orchards. Furthermore, we observed that this beetle colonizes trees in nurseries, which constitutes an important means of dispersion. We also noticed its reproduction in a recently pruned olive trunk 30 cm in diameter. Damage by other organisms (leaf feeding) reached 13% of leaves on new sprouts, resulting in the loss of 7% of foliar extension.
