A hyperparasite is defined as an insect which is able to parasitise some other parasitic insect. Which of the following parasites is a well known hyperparasite of powdery mildews?

 Ampelomyces quisqualis is an anamorphic fungus that is a hyperparasite of powdery mildews. This parasitism reduces growth and may eventually kill the mildew. L. longisporum is used for management of aphid pests. Insects are infected when they come into contact with the sticky fungal spores which then grow and invade the body. Thus the internal organs are consumed.
