Artificial media for rearing entomophages

摘要

An improved artificial diet or growth medium for rearing entomophages (predatory arthropods and parasitic insects). The diet also finds use as a bait and feeding stimulant for entomophages, and as use as a supplement for artificial diets for phytophagous pests that also display some insect consumption. The growth medium is composed of a mixture of (a) an adherent, fibrous retention substrate, (b) a protein-lipid paste, and (c) a liquid, and provides nutrients in a stabilized form in amounts and proportions effective to support growth of entomophages. An exemplary formulation is a mixture of adherent, fibrous cooked whole egg, ground beef and beef liver protein-lipid paste, and water. The growth medium is suitable for mass production of entomophages at a reasonable cost for use as biological control agents, and is well suited for rearing entomophages that feed by the process of extra-oral digestion.
