Microplitis is the main vector of ascovirus and so plays a key role in increasing the percentage of caterpillars affected by this disease... High levels of ascovirus may lead to a decline in Microplitis wasp populations... small pale caterpillars in unusually exposed situations (e.g. on a leaf) that look as though they have been feeding in the same place for some time, making a window in the leaf, are probably infected with ascovirus because infected caterpillars can take a long time to die, ascovirus infection in the population can show up in crop scouting data over a series of checks as a number of small caterpillars (shorter than 8 mm) in the crop, with very few medium-large caterpillars coming through...
