COMPOSITIONS AND METHODS TO CONTROL INSECT PESTS
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, dec...

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. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
Se proporcionan métodos y composiciones que emplean un elemento de silenciamiento que, cuando se ingiere por una plaga de insectos de plantas, tal como una plaga de coleópteros, hemípteros o lepidópteros de plantas, incluyendo una plaga de Diabrotica, Leptinotarsa, Phyllotreta, Acyrthosiphan, Bemisia, Halyomorpha, Nezara o Spodoptera de plantas, disminuye la expresión de una secuencia diana en la plaga. Se divulgan diversos polinucleótidos diana expuestos en una cualquiera de las SEQ ID NO: 1-53 o 107-254 desveladas en este documento, o variantes y fragmentos de las mismas, o complementos de las mismas, donde una reducción de la expresión de una o más de las secuencias en la plaga diana controla la plaga o población de plaga por esterilización de insectos (es decir, esterilidad de machos y hembras, reducción del recuento de espermatozoides, producción y viabilidad de huevos) y técnica de insectos estériles basada en apareamiento (SIT). También se proporcionan plantas, partes de plantas, bacterias y otras células hospedadoras que comprenden los elementos de silenciamiento o una variante activa o fragmento de los mismos de la invención. Se pretende que este resumen sea una herramienta de exploración para fines de búsqueda en la técnica particular y no se pretende que sea limitante de la presente invención. |
