Verticillium lecanii is biopesticide widely used to control white flies, aphids, thrips, mealy bugs etc. ,
Verticillium lecanii is an entomopathogenic fungus. The mycelium of this fungus produces a cyclodepsipeptide toxin called bassianolide and other insecticidal toxins such as dipicolinic acid, which infect aphids, whiteflies, rust fungi, scale insects and lead to death the host.
Mode of action
The spores of this fungus when come in contact with the cuticle (skin) of target insects, they germinate and grow directly through the cuticle to the inner body of their host. The fungus proliferates throughout the insects body, draining the insect of nutrients, and eventually killing it in around and a week time. The spores of Verticillium lecanii infect the insect with contact and do not need to be consumed by their host to cause infection.
