Abstract (en):
The presence of the giant African snail Achatina fulica (Bowdich 1822) was confirmed in Colombia in 2008. Due to economic and health implications of this species and the difficulties in controlling it, it is essential to establish the relevance of protocols and alternative inexpensive substances used to control the snail. In this research, the effectiveness of manual removal and manual removal with spray of calcium oxide was analyzed. Both techniques had similar efficiencies, so it is recommended that calcium oxide should be implemented only for the disposal of the collected individuals in order to reduce costs and decrease the impact on arthropofauna. In addition, we evaluated the molluscicide ability of commercial sodium hypochlorite, two plant extracts (Tabebuia rosea and Jatropha curcas), and commercial molluscicide (metaldehyde). We found that the three
alternative substances were effective as molluscicides, but with lower effectiveness than the commercial substance. Implementation of the extracts of T. rosea and J. curcas is recommended because they have low cost, and do not present negative effects on the environment.
Abstract (es):
La presencia del caracol gigante africano Achatina fulica (Bowdich 1822) fue confirmada en Colombia en 2008. Debido a las implicaciones económicas y sanitarias que representa esta especie, así como las dificultades de su control y el alto costo que esté representa, se ha generado la necesidad de cuantificar la efectividad de los protocolos implementados para su control y el uso de sustancias alternativas de bajo costo. En la presente investigación se analizó la eficacia de la remoción manual y la remoción manual con aspersión de cal (óxido de calcio). Ambas técnicas presentaron eficacias similares, por lo cual se recomienda que la cal solo sea implementada para la disposición final de los individuos colectados, disminuyendo costos y repercusiones en la artropofauna. Adicionalmente, se evaluó la actividad molusquicida del hipoclorito de sodio comercial y el extracto vegetal de Tabebuia rosea y Jatropha curcas, comparándose con una sustancia molusquicida comercial (metaldehído). Las tres sustancias alternativas presentaron actividad molusquicida, con una eficacia menor a la sustancia comercial. La implementación del uso de los extractos de T. rosea y J. curcas en los programas de control del caracol africano podría ser relevante, debido a su bajo costo y la ausencia de efectos ambientales negativos.
