摘要： An insect control sheet containing a Cry polyhedron prepared by fixing an insecticidal protein (a Cry toxin) produced by Bacillus thuringiensis to a polyhedron of polyhedrin protein is provided. The insect control sheet contains the Cry polyhedron and is used by floating on water. The insect control sheet is floatable on water, and includes a pure matrix layer 20 and a toxin-containing matrix layer 30 containing the Cry polyhedron 51 which are layered on the underside of a sheet-shaped first sheet substrate 10. The pure matrix layer 20 is composed of a degradable or water-soluble second material and the toxin-containing matrix layer 30 is composed of a degradable or water-soluble third material and the Cry polyhedron. The toxin-containing matrix layer sustainably releases the Cry polyhedron to the water on which the insect control sheet is floated.
