A new endophytic Penicillium oxalicum with aphicidal activity and its infection mechanism.

Background: Aphid infestation adversely affects the yield and quality of crops. Rapid reproduction and insecticidal resistance have made controlling aphids in the field challenging. Therefore, the present study investigated the insecticidal property of Penicillium oxalicum (QLhf-1) and its mechanism of action against aphids, Hyalopterus arundimis Fabricius.

Discovery, Identification, and Insecticidal Activity of an Strain Isolated from a Saline-Alkali Soil Sample.

Aphids are one of the most destructive pests in agricultural production. In addition, aphids are able to easily develop resistance to chemical insecticides due to their rapid reproduction and short generation periods. To explore an effective and environmentally friendly aphid control strategy, we isolated and examined a fungus with aphid-parasitizing activity.
