Publication number: 20240084319Abstract: Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a Coleopteran plant pest or a Diabrotica plant pest, decrease the expression of a target sequence in the pest. 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.Type: ApplicationFiled: April 27, 2023Publication date: March 14, 2024Applicants: PIONEER HI-BRED INTERNATIONAL, INC., E.I.

Publication number: 20240002842Abstract: Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a Coleopteran plant pest or a Diabrotica 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: disclosed herein, (but not including the forward and reverse primers.) or active 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 (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 embodiments, the pest is D. virgifera virgifera, D. barberi, D. virgifera zeae, D. speciosa, D.Type: ApplicationFiled: August 22, 2022Publication date: January 4, 2024Applicants: PIONEER HI-BRED INTERNATIONAL, INC., E.

Publication number: 20220267792Abstract: 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.Type: ApplicationFiled: April 29, 2022Publication date: August 25, 2022Applicants: PIONEER HI-BRED INTERNATIONAL, INC., E.
