Image of a Microplitis demolitor wasp stinging a helicoverpa larva.. Microplitis adult aproaching a helicoverpa larva... Look for them flying above the crop or use a sweep net to sample the crop collect caterpillars shorter that 15 mm and perform the split test to estimate percent parasitism (number parasitised total larvae split x 100) look for visible signs of parasitoid activity, e.g. the distinctive fawn cocoons and/or small pale caterpillars that might be infected with ascovirus cross-check crop scouting data - if eggs and very small caterpillars do not seem to be developing through to larger caterpillars (>15 mm), this may be due to Microplitis activity...
