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...

Orange caterpillar parasite, Netelia producta, egg attached to host larva.. With the host paralysed, the wasp moves in and lays a brown egg onto the skin of the caterpillar, close to the head... The immature Netelia larva hatches from the egg and develops externally, hanging on behind the head of the caterpillar...
