The heliothis caterpillar is a serious insect pest of vegetables in Australia. The larvae cause obvious feeding damage in vegetables, rendering them unsuitable for sale as fresh produce. The combined effects of insecticide resistance and increased public concern about the environmental safety of using chemical insecticides suggests that chemicals will not remain the sole pest management tool for the vegetable industry in the future. This project evaluated new ways of killing heliothis that may be useful in an Integrated Pest Management (IPM) approach to pest management. Two new tactics were investigated for this report. One involved using parasitic wasps that attack heliothis eggs and the other involved using a viral pathogen that only kills heliothis caterpillars.These tactics were studied in lettuce and sweet corn.
