ABSTRACT

Field-collected insects were examined to identify potential predators of Bemisia tabaci and Pectinophora gossypiella using a multiple serodiagnostic enzyme-linked immunosorbent assay (MS ELISA). An anti-B. tabaci and an anti-P. gossypiella monoclonal antibody (MAb) was used to detect the presence of pest egg antigen in predator guts. Collops vittatus and Orius tristicolor had the greatest number of individuals scoring positive for B. tabaci egg antigen. Very few of the predators we examined contained P. gossypiella egg antigen in their systems, indicating that P. gossypiella was not preyed upon as frequently as B. tabaci.
