Abstract
Rhizophora harrisonii foliar damage was assessed in the Trinitarian and Chupador Chico Islands of the Gulf of Guayaquil, during the dry and rainy seasons, 2016-2017 using the Creative Cloud software of the Adobe Photoshop Extended program for the measurement of foliar damage by necrosis, chlorosis and browsing caused by Thyrinteina arnobia Stoll. As well as the stomatic index, and the pH. Simple one-way ANOVA was used and they were validated with the Kruskal Wallis test for non-parametric samples. It was found that 40% of the samples collected on the Trinitarian Island are affected, but not the mangrove of Chupador Chico, where the presence of Thyrinteina was not found. Temporary differences on leaf damage intensify during the dry season, its presence is considered to have responded to a pest behavior, which was triggered by the anormal environmental conditions that occurred at that time.
