摘要：

Infection of larvae of Trichoplusia ni (Hübner) by Vairimorpha, (=Nosema) necatrix was classified as chronic, semi-chronic and acute symptoms depending on the quantity of spores (5 to 500, 5×103 to 5×105, and 5×106 per larva, respectively) ingested per larva. V. necatrix infects mainly the fat body and some muscle tissue of larvae with chronic symptoms and mainly midgut tissue of larvae with acute symptoms. V. necatrix caused death in 3 to 4.5 days when a larva ingested 5×106 spores. The histopathology of the disease was studied. © 1979 Le François.
