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...

" Print the page sitona weevil, Sitona discoideus, scalloped leaf damage Scalloped leaf damage... Larvae feed within or on the root nodules and can cause more serious damage than adults by reducing nitrogen fixation and retarding plant growth... Larvae feed through the winter and early spring to pupate in the soil and emerge as adults in late spring/early summer...
