Cadavers of Phenacoccus solenopsis Tinsley were collected from locations in Haryana and Punjab during 2007-2010. The entomofungal pathogen, Fusarium pallidoroseum (Cooke) Sacc., was consistently isolated from all locations during three seasons. The recovery of the entomopathogen varied among locations and seasons. Koch's postulates were proved by reisolating the same fungus from infected mealybugs. In the laboratory, F. pallidoroseum caused 80-95% mortality of P. solenopsis.

Abstract


Cadavers of Phenacoccus solenopsis Tinsley were collected from locations in Haryana and Punjab during 2007-2010. The entomofungal pathogen, Fusarium pallidoroseum (Cooke) Sacc., was consistently isolated from all locations during three seasons. The recovery of the entomopathogen varied among locations and seasons. Koch's postulates were proved by reisolating the same fungus from infected mealybugs. In the laboratory, F. pallidoroseum caused 80-95% mortality of P. solenopsis.
