Abstract
Increased pest control by generalist predators has been successfully achieved in several cases by promoting apparent competition, which is the reciprocal negative interactions between prey mediated by their shared predator. However, the presence of alternative prey does not always result in an improved control of the target pest species, due to the complexity and specificity of biotic interactions. To increase the effectiveness of IPM programs, a fine understanding of the interactions among co-occurring pest species and their biocontrol agents is necessary. We tested the occurrence of apparent competition between the major tomato pests Tuta absoluta and Bemisia tabaci when preyed on by a generalist mirid bug Macrolophus pygmaeus, by monitoring pest and predator population dynamics in a greenhouse experiment. We also measured the cascading effect of the shared predator on plant and fruit damage due to pests. We observed higher predator population growth and reduced population densities of both prey in treatments with two prey, as compared to treatments with one prey, showing that apparent competition occurred. Plant and fruit damage caused by B. tabaci was reduced in the presence of T. absoluta, but damage due to T. absoluta, which accounted for the major part, was not reduced in the presence of B. tabaci, resulting in similar levels of total damage when pests co-occurred. This study demonstrates that, even if promoting apparent competition leads to actual reduction in pest densities, yield loss may not be reduced when this strategy is applied to major pests such as T. absoluta.
