PARASITISM-SPECIFIC PROTEIN 15 GENE DERIVED FROM A POLYDNAVIRUS AND ITS USE

摘要

The parasitism-specific protein 15(PSP15) derived from a polydnavirus is provided to inhibit synthetic capacity of the host insect specific protein, thereby being used in a biological pesticide for improving insecticidal capacity thereof. The PSP15 capable of lowering protein synthetic capacity of insects has more than 90% homology to an amino acid sequence encoded by a PSP15 alpha gene described as SEQ ID : NO. 1 or a PSP15 beta gene described as SEQ ID : NO. 2 and has an E value of 0.006 with circumsporozoite. The insecticide comprises the PSP15 protein as an effective ingredient.
