ABSTRACT:
Methods for packaging Metarhizium fungal cultures or conidia are described. In one embodiment, the fungal culture is provided within an insect infection chamber that attracts insects, then infects them with a lethal dosage of fungus, where the packaging maintains high humidity within the chamber, allows free exchange of gases, and is impermeable to microbes, including fungal spores, viruses, and bacteria. In a second embodiment, the fungal conidia are packaged under conditions which maintain high viability even after long-term storage at both 25.degree. C. and 37.degree. C., i.e., low relative humidity and oxygen. The conidia can then be reactivated for the use in the control of insects such as cockroaches, flies, ants, soft-bodied insects, turf pests, and caterpillars.
