  • Patent number: 10246710
    Abstract: The present disclosure provides compositions and methods of delivering double strand ribonucleic acid (dsRNA) to control the insect pest, the brown marmorated stink bug. Several dsRNA species that target genes are disclosed herein that can be used individually or in combination. The dsRNA species can be used to induce RNA-mediated interference (RNAi) to decrease target gene expression. RNAi can be used alone, or in combination with other pest control measures to target the brown marmorated stink bug.

  • Publication number: 20190048360
    Abstract: The present invention relates to the field of double-stranded RNA (dsRNA)-mediated gene silencing in insect species. More particularly, the present invention relates to genetic constructs designed for the expression of dsRNA corresponding to novel target genes in the insect pest Lymantria dispar, commonly known as the gypsy moth. The present invention also provides methodologies for introducing dsRNA into target insects to induce RNA interference. These constructs are particularly useful in RNAi-mediated control of the gypsy moth.

  • Publication number: 20180023076
    Abstract: The present disclosure provides compositions and methods of delivering double strand ribonucleic acid (dsRNA) to insects that penetrate plant tissues to feed on sap and other liquid components of plants. Taking advantage of the liquid transport capabilities of plant vascular structures, dsRNA is provided to plant tissues in an aqueous solution that is then transported throughout the tissues. The dsRNA-laden plant material is then presented to insects that can ingest the dsRNA by feeding on the plant tissue.
