  • Patent number: 6204433
    Abstract: This invention relates to methods for transforming arthropods with exogenous DNA. The methods are useful for arthropods that have not previously been amenable to DNA-mediated transformation, and also provide a simpler and more efficient means of transforming arthropods than have previously been described. The method involves microinjecting a nucleic acid sequence encoding a desired trait into the reproductive tract of a female arthropod before oviposition.
    Type: Grant
