[Effect of Pleistophora carpocapsae and P. schubergi microsporidians on the growth, development and mortality of lackey moth caterpillars].

The microsporidian Pleistophora carpocapsae does not influence the growth, development and mortality of its host--the caterpiller Malacosoma neustria L. On the other hand P. schubergi causes sireous desturbances of the insects functions: stimulation of growth just after the infection, its opression and retardation of development during the next stage of the disease. All this results in the fatal end.
