    摘要: Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a pest from the Aphididae family, 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 for specific protein classes and also target polynucleotides as set forth in SEQ ID NOS:1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or active variants or 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 Aphis glycines. Plants, plant part, bacteria and other host cells comprising the silencing elements or an active variant or fragment thereof of the invention are also provided.
