Fuente: WIPO "tomato" Disclosed are the H. zea nudivirus sequence, two additional related sequences from H. virescens and H. armigera nudiviruses for development of genetically modified nudiviruses capable of being sexually transmitted by an insect useful for controlling pest populations, methods for preparing egg populations for controlling pest populations and methods for controlling pest populations utilizing such egg populations. Such genetically modified nudiviruses are capable of causing sterility in a target population of insects. Previously disclosed were insects infected with the previously disclosed genetically modified H. zea nudivirus, methods of making genetically modified nudiviruses, and methods of using genetically modified nudiviruses to control an insect pest population.
