  • Publication number: 20220267792
    Abstract: Methods and compositions are provided which employ a silencing element that, when ingested by a plant insect pest, such as Coleopteran, Hemiptera, or Lepidopteran plant pest, including a Diabrotica, Leptinotarsa, Phyllotreta, Acyrthosiphan, Bemisia, Halyomorpha, Nezara, or Spodoptera plant pest, decrease the expression of a target sequence in the pest. Disclosed are various target polynucleotides set forth in any one of SEQ ID NOS: 1-53 or 107-254 disclosed herein, or variants and fragments thereof, or complements thereof, wherein a decrease in expression of one or more of the sequences in the target pest controls the pest and pest population by insect sterilization (i.e., male and female sterility, reduction of sperm count, egg production and viability) and mating-based sterile insect technique (SIT). Plants, plant parts, bacteria and other host cells comprising the silencing elements or an active variant or fragment thereof of the invention are also provided.

  • Patent number: 10876132
    Abstract: Compositions and methods for controlling pests are provided. The methods involve transforming organisms with one or more nucleic acid sequence encoding insecticidal protein(s) and one or more silencing element(s). In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest including plants, as probes for the isolation of other homologous (or partially homologous) genes. The molecular and breeding stacks find use in controlling, inhibiting growth or killing Lepidopteran, Coleopteran, Dipteran, fungal, Hemipteran and nematode pest populations and for producing compositions with insecticidal activity.

  • Publication number: 20190271004
    Abstract: Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a pest from the Lepidoptera order, they are capable of decreasing the expression of a target sequence in the pest. In specific embodiments, the decrease in expression of the target sequence controls the pest and thereby the methods and compositions are capable of limiting damage to a plant. The present invention provides target polynucleotides encoding polypeptides from specific protein families and various target polynucleotides set forth in SEQ ID NOS: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 or active variants and fragments thereof, wherein a decrease in expression of one or more the sequences in the target pest controls the pest (i.e., has insecticidal activity).

    Abstract: Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a Pentatomidae plant pest or a N. viridula, Acrosternum hilare, Piezodorus guildini, and/or Halymorpha halys plant pest, decrease the expression of a target sequence in the pest. In specific embodiments, the decrease in expression of the target sequence controls the pest and thereby the methods and compositions are capable of limiting damage to a plant. The present invention provides various target polynucleotides set forth in any one of SEQ ID NOS: 1-292 or 302-304 or active variants and fragments thereof, wherein a decrease in expression of one or more the sequences in the target pest controls the pest (i.e., has insecticidal activity). Further provided are silencing elements which when ingested by the pest decrease the level of the target polypeptide and thereby control the pest. In specific embodiment, the pest is Pentatomidae.
