Resumen en inglés

Arsenura armida plays an important ecological role in the development of woods and forests throughout Latin America. It is also consumed in several rural communities of Mexico. At present, there is no information on the host preferences of this species of moth, habitat type or the effects of human consumption on population numbers. This paper determines the effect of agricultural management on the distribution, occupation and abundance of larvae of A. armida in order to promote strategies for its sustainable exploitation. Six observation plots, each with an area of 4 km², were established in three localities of the state of Chiapas, Mexico. Three plots were subject to agricultural management (La Pimienta, La Ilusion and La Loma) and three without management (Carrizal, Huachinadero and Mirador). All host plants together with their diameter at breast height (DBH) were quantified. In order to estimate host preference, occupation, distribution and abundance, the number of larvae per tree were recorded over two consecutive years (between March and October). The occupation and abundance of A. armida varied among plots and the six tree species observed. Both variables presented a relationship with the mean DBH of the host species. A preference for the host species Heliocarpus appendiculatus and Rollinia mucosa was observed. The greatest abundance of larvae and host occupation was found in plots subject to agricultural management during the first year. Abundance decreased during the second year due to tree mortality. The insect presented a clustered distribution that depended on the distribution and development of host trees (highest DBH). It is suggested that host management is considered for the control of populations of A. armida in agricultural areas and its sustainable exploitation for human consumption.

Resumen en español

Se evaluó la germinación y supervivencia in situ y ex situ de plántulas de Aspidosperma megalocarpon, Eugenia sp., Lonchocarpus castilloi, Manilkara zapota, Ormosia macrocalyx y Rollinia mucosa. En campo se sembraron 2 160 semillas en nueve bloques de 5 m x 20 m distribuidos en bosque tropical, acahual maduro y acahual joven. El experimento se replicó en condiciones de vivero bajo sombra de 40, 60 y 80%. Los tipos de cobertura vegetal no mostraron diferencias significativas en las tasas de germinación y de crecimiento; sin embargo, estos sí influyeron en la capacidad de germinación de A. megalocarpon y O. macrocalyx, y en las tasas de depredación de M. zapota y L. castilloi. En el acahual joven se presentó la mayor depredación de semillas, sin embargo, las plántulas remanentes presentaron mayor supervivencia que en las otras coberturas vegetales. En el vivero no se encontró diferencia en la proporción de semillas germinadas, ni en las tasas de germinación y de crecimiento. R. mucosa, fue la única especie que presentó menor supervivencia (42%). Las condiciones ambientales de las diferentes clases de cobertura vegetal en el área de estudio mantienen condiciones adecuadas para el proceso de germinación, crecimiento y establecimiento de plántulas de las especies estudiadas, lo cual permite sugerir su utilización en la rehabilitación de áreas degradadas del bosque original sembrando de manera directa, siempre y cuando se realice de manera inmediata después de la recolecta. Es necesario continuar con estos estudios para promover el uso de especies nativas en la rehabilitación y restauración de bosques tropicales.

Resumen en inglés

We evaluated the germination and survival in situ and ex situ of seedlings of Aspidosperma megalocarpon, Eugenia sp., Lonchocarpus castilloi, Manilkara zapota, Ormosia macrocalyx and Rollinia mucosa. We established nine blocks of 5 m x 20 m in the field, in which 360 seeds of each species were established in three successional conditions with three repetitions: mature tropical forest, advanced fallows and young fallows. The experiment was replied in a tree nursery using 40, 60 and 80% shade. We found no significant differences in the rates of germination and neither in growth due to variation in the natural cover. However, the rates of germination of A. megalocarpon and O. macrocalyx, and the rates of depredation of M. zapota and L. castilloi were affected by the coverage. Seeds sown in young fallows showed higher depredation, whereas seedling survival was higher here than in the other successional stages. In the tree nursery, no significant difference was found in the proportion of germinated seeds, the rates of germination and in growth. However, R. mucosa showed low survival (42%). The environmental conditions of the forests in Tabasco are under various stages of degradation and it is appropriate to start a rehabilitation program by introducing native species. This study indicates that this could be done by sowing the seeds directly in the forests without first producing seedlings in nurseries, which in turn would reduce the costs. It is recommend continuing research on the seed and seedling performance of other species that could be used to rehabilitate and restore the tropical forest.
