Síntomas, signos e incidencia de insectos y fitopatógenos asociados a especies de mangle Symptoms, Signs, and Incidence of Insects and Phytopathogens Associated with Mangrove Species

Abstract

The research took place in the mangrove ecosystem of the Coloma-Las Canas Sector and had the objective of “diagnosing the phytosanitary status of the different species that compose it.” For this, 10 monitoring sites of 10X10 meters were established, according to Bernal (2017) criteria. The distribution in the field of these sampling units was done at random. To carry out the field data collection, a monitoring brigade made up of 4 researchers participated, who were trained with theory and practice in the field on topics related to mangrove monitoring and its effects, placing emphasis on the identification of symptoms and signs of possible causal agents of damage located in the area. Photos were taken (using a cell phone camera) of the symptoms and signs of causal agents (both insects and diseases) and subsequently, through the search for scientific information, their respective identifications were carried out. Likewise, broken and dead trees were counted in each plot. From the field data, the degree of incidence of pests on each of the mangrove species was determined, for which the following expression was used: D=No of infested trees/Total number of individuals censused * 100 All of these Data were processed in Microsoft Excel. Among the organisms detected, Junonia sp, a defoliating pest of A. germinans, as well as ends and cankers produced by pathogens were inventoried.
