Biological contro of the red palm weevil phynchophous ferrugineus (Olivier)‎ coleopetra: curuculionisea)‎ by the parasi-toid mite, phynchopolipus phynchophori ( Ewing )‎( acarina : podap-olipidea)‎

Abstract EN

The parasitoid mite, Rhynchopolipus rhynchophori was released against the red palm weevil Rhynchophorus ferrugineus stages.

Released of this mite ap¬plied at four levels of treatment, A (30 parasitic mites: 1 prey), B (60 parasitic mites: 1 prey), C (90 parasitic mites: 1 prey) and D (120 parasitic mites: 1 prey).

The parasitoid mites successfully suppressed population density of the red palm weevil, R.

ferrugineus stages within two weeks.

The killing of differ¬ent developmental stages of the red palm is due to sucking their body fluid by the parasitoid mite, Rh.

rhynchphori.

But, the pupal weight was significantly (P<0.5) decreased by increasing numbers of parasitoid mites at the different treatment levels
