Abstract - Apis cerana colonies, surviving from Thai Sacbrood Virus disease, showed disease symptoms earlier, with more severity and with a greater reduction in prolificness in parent than in daughter, colonies. Parent colonies also took longer to recover from infection and showed abnormal behaviour compared to daughters colonies. No such symptoms were observed in control A cerana and A mellifera (virus fed) colonies.
Key words: Apis cerana / Thai Sacbrood Virus / virus disease / sacbrood
