It is an entomopathogenic fungal agent with epidermal and pupal sensitivity of insects.
The hyphae of the entomopathogenic fungi Lecanicillium and Paecilomyces lilacinus invade thrips pupae and have insecticidal effects.
Chitin, protein and lipid degrading enzymes produced from hyphae of entomopathogenic fungi Lecanicillium and Paecilomyces lilacinus perforate the epidermis of thrips pupae, secrete Bassinolide insect pathogenic toxin inside, spread and proliferate, and It inhibits or kills the eclosion process that progresses to adulthood.
