Mode of action

Adult female parasitic wasp parasitizes mealy bugs, mainly the second larval stage.

 

Visual effect

A few days after the mealy bug larvae is parasitized the colour change to brownish. However most of the parasitized larvae fall down from the plant, which makes it difficult to monitor the effect.
