Metarhizium majus

Metarhizium majus is the name given to a group of fungal isolates that are known to be virulent against , a family of beetles. Previously, this species has had variety status in "Metarhizium anisopliae" (var. "majus") and its name is derived from characteristically very large spores (typically 2.5–4 µm x 10–14 µm long) for the genus "Metarhizium". There has been considerable interest in developing isolates of this species into mycoinsecticides: especially for coconut and oil palm beetle pests in SE Asia, the Pacific region and Africa.
It is an anamorph, its telomorphic form is "Cordyceps brittlebankisoides".
