  • RNAi Insecticide Materials and Methods
    Publication number: 20220346380
    Abstract: The present invention provides a novel class of insecticides for control of disease vector insects, particularly mosquitoes. These insecticides prevent maturation or development of larvae into adult insects using interfering RNA (iRNA). The present invention further includes compositions comprising iRNA and methods of controlling, reducing, or treating an insect infestation with the iRNA or compositions described herein.
    Type: Application
    Filed: January 7, 2022
    Publication date: November 3, 2022
    Applicants: Indiana University Research and Technology Corporation, University of Notre Dame du Lac
    Inventors: Molly Duman Scheel, David W. Severson, Kathleen Eggleson, Na Wei

  • Identification of africanized honey bees
    Patent number: 5013644
    Abstract: Africanized honey bees are identified by using a DNA probe capable of identifying a specific repeating gene sequence in the honey bee DNA which is a diagnostic characteristic of African honey bees when located on a defined restriction endonuclease fragment from bee genomic DNA. When the DNA probe is applied to an electrophoresis gel on which the restriction fragments are resolved, the probe hybridizes to the diagnostic fragment, if present. The hybridization to the repeating sequence can then be detected by detection of the marker.
