After penetrating the outside skeleton of the insect, they grow rapidly inside the insect, causing the insect to die.
Why are Metarhizium fungi a better candidate for insect control?
According to the article, why are Metarhizium fungi a better candidate for insect control than Ophiocordyceps and Cordyceps? ... This type of fungi are limiting because they rely on that certain species of ant to reproduce, & therefore play a limiting role in insect control.
What is metarhizium SPP?

Mycotrol ESO and Mycotrol WPO are the two new organic-approved formulations of B. bassiana registered for various pests for different situations. Both formulations have WSDA organic certifications.
Can Entomopathogenic Fungi affect humans?
Entomopathogenic fungi are microorganisms that specifically infect and often kill insects and other arthropods. Most are nonpathogenic to plants, and relatively non-toxic to humans and animals.
How long does it take for BotaniGard to work?
Typically, it takes 7-10 days after the first spray to see control. Application rates, frequency, spray coverage and insect numbers impact the speed at which acceptable control is achieved. BotaniGard ES is most effective when used early, before high insect populations develop.
How do you use green beauveria?

How is Beauveria bassiana made?
Most of the production of B. bassiana spores in Colombia for coffee berry borer biocontrol is done using a simple sterilization technique based on cooked rice placed inside bottles. The spores are mainly used for field spray applications (Posada 1993; Bustillo and Posada 1996).
What is used in mass multiplication of metarhizium?
The two-phase culture (liquid and solid) is the most commonly used technique to mass produce Metarhizium.
What is Muscardine disease?
Muscardine is a disease of insects. It is caused by many species of entomopathogenic fungus. Many muscardines are known for affecting silkworms. Muscardine may also be called calcino. While studying muscardine in silkworms in the 19th century, Agostino Bassi found that the causal agent was a fungus.
