Abstract

Mass rearing Wiseana (porina) species, a major endemic insect pest in New  Zealand pastures, has proved challenging for research and pest management and has  presented problems over several decades in the laboratory. Researchers have acknowledged  that handling the eggs and first instar larvae are of critical importance during laboratory  rearing. A simple method is presented that improves survival of early instar porina larvae.  Eggs of three porina species (W. cervinata, W. copularis, W. umbraculata) hatched faster at  22°C than at 15°C.
