Assays to determine the predatory ability of Pergamasus against clover flea

Clover flea (Sminthurus viridis) is found throughout New Zealand and is a major economic pest of white clover (Trifolium repens) in localised areas of the North Island Predatory mites are important biocontrol agents of clover flea in Australia but little is known of the efficacy of the predatory mite species present in New Zealand A major challenge to assessing mite efficacy has been poor survival of clover flea in laboratory assays It was found that adult clover flea survival was higher when they were contained with soil whereas soil was not essential for the survival of younger nymphs The predatory ability of Pergamasus is still unclear as there was significant mortality in one experiment containing the mites but no significant difference in mortality in the assay that followed
