Summary[edit] Description: English: Inside one of these plump wax moth cadavers are thousands of wiggly nematodes, ready to serve as biocontrols against soil-dwelling crop pests. The cadavers can be placed in orchard or greenhouse soil, and the nematodes will emerge to protect crops from pests such as citrus root and black vine weevils. Date: 3 March 2003.
