Biological control of giant salvinia: using new technology in Puerto Rico.

Abstract

This paper provides information on the promising results of the use of the salvinia weevil in the biological control of giant salvinia, a highly invasive weed of freshwater lakes in Puerto Rico. If successful, the implementation of the biological control program at various locations will result in the recovery of native plants and animals and improve water quality and ecological services provided by the lakes. Moreover, economic benefits will result from the reduction in control costs involved in the use of herbicides or mechanical harvesters and from the increase in revenue because of the improved navigation and access to fishing and tourism.
