Beneficial insects, predatory mites and entomopathogenic nematodes: 37 species with their biology and release rates

Thirty-seven beneficial organisms available on the Greek market, with their life cycle, published temperature thresholds, humidity limits and release rates. Why they hold no authorisation number and what they hold instead: the Greek national catalogue of preparations containing macro-organisms and Ministerial Decision 10522/117908. An interactive selection tool by crop and pest, a full searchable table, release rates from peer-reviewed work, IOBC compatibility with plant protection products, and eight documented ways a release fails. Photoperiod, Greek summer temperature and humidity as the real limiting factors.
