“…After repeated encountering of flabby larvae in artificial diet rearing, using CRA-API's diet containing chloramphenicol, which occurred both in Padua and in other European labs, we focused our efforts on isolation of possible etiological agent for the so-called ''flacherie'' disease. Larvae showing symptoms of retarded growth, cessation of feeding, flaccidity, loss of body lustre, sluggishness and dysentery can be affected by bacteria or viruses (Aizawa et al, 1964;Tanada and Kaya, 1993;Lysenko, 1958) or even by two microbial agents (Manimegalai, 2009;Deseö Kovács and Rovesti, 1992).…”
