Bacillus subtilis YZ‐1 surfactins are involved in effective toxicity against agricultural pests

Insect pests negatively affect crop quality and yield. The excessive use of chemical pesticides has serious impacts on the environment and food safety. Therefore, development of effective management strategies in the form of bio-agents have important agricultural applications. Tenebrio molitor, a storage pest, causes losses of grains, medicinal materials, and various agricultural and related products in the warehouse. Bacillus subtilis YZ-1 isolated from naturally deceased Pieris rapae has been found to exhibit significant toxicity against T. molitor.
