Abstract: The present invention provides an antibody fusion protein, comprising an antitumor antigen-specific antibody or a Fab fragment thereof, a single domain antibody or single chain antibody, and further comprising a human NKG2D ligand or ligand fragment. The human NKG2D ligand or ligand fragment and the antitumor antigen-specific antibody or Fab fragment thereof and the single domain antibody or single chain antibody are mutually connected by a linker peptide.

Abstract: Certain embodiments of the present invention provide a method for controlling Athetis lepigone, which comprises contacting Athetis lepigone with Cry1F protein. Aspects of the present invention can achieve control of Athetis lepigone by enabling plants to produce Cry1F protein in vivo, which can be lethal to Athetis lepigone. In still other instances, the method can control Athetis lepigone throughout the growth period of the plants and provide the plants with a full protection. Additionally, the method, in certain embodiments, can be one or more of stable, complete, simple, convenient, economical, pollution-free or residue-free.
