The series of investigations have been carried out on the effect of the entomopathogenic fungi Beauveria bassiana on the various developmental stages of Phthorimaea operculella. Both first and second instar larvae were more susceptible than the third of fourth instars. The infected prepupae and pupae resulted in marked decreases in the emergence and longevity of moths, deposited eggs and their egg hatchability. An obvious increase in the pupal duration was observed and the resulting malformed adults were also recorded. The latent were markedly obvious, specially in high doses of B. bassiana.

Keywords: Beauveria bassiana, entomopathogenic fungi, Phthorimaea operculella.
