The striped cucumber beetle [Acalymma vittatum] is a serious pest of cucurbits. Unfortunately, insecticides are still the most effective pest management strategy to control striped cucumber beetles which add additional hurdles to organic growers who cannot rely on chemical control. One alternative option is biological control, or the use of a natural enemy or predator to reduce pest populations. The parasitoid tachinid fly species, Celatoria setosa, is a highly effective predator of striped cucumber beetles but has only been successfully reared on small scales. In this presentation, we report on an updated methodology for rearing Celatoria setosa in hopes to make the species available for application as a biological control in the field.
