Commercialization of predators: recent lessons from green lacewings (Neuroptera:Chrysopidae:Chrysoperla)

Significant new developments in artificial larval diets, mechanized production methods, long-term storage, and quality control can reduce the cost and increase the availability and reliability of mass-reared Chrysoperla spp. Similarly, a re-examination of existing information on the chemical ecology and movement of lacewings reveals ways for improving the ability to attract and retain their populations in agricultural situations. Furthermore, the efficacy of procedures for both releasing and attracting Chrysoperla is being evaluated rigorously with quantitative methods under field conditions.
