Beneficial nematodes that can attack and kill corn rootworm must be mass-produced before distribution. Here, a cadaver of a waxworm larva (right) serves as a host “factory” for nematodes feeding within it. Inset: A microscopic view of the thread-like nematodes (white arrows point to several; the gray arrow points to a nerve of the insect host) inside the cadaver.
