“…M. aequalis and M. ciliata also occur in pastures, arable crops, horticultural land and other modified habitat in the UK and mainland Europe (e.g. Boness, 1958;Disney, 1980aDisney, , 1989Disney and Gunn, 1980;Disney et al, 1981a,b;Froese, 1992a-c), indicating at least some persistence of the adult stage in these managed systems. However, it is presently not known to what degree M. aequalis and M. ciliata are able to parasitize Deroceras eggs in these environments.…”
