摘要

These are methods and compositions which employ a silencing element which, when ingested by a plant pest insect such as a coleoptera, hemiptera or lepidoptera plant pest, including a diabrotic, leptinotarsa, phyllotreta, acyrthosiphan, bemisia, halyomorpha, nezara or spodoptera, decreases the expression of a target sequence in the pest. various target polynucleotides disclosed in any one of the following sequences are disclosed: 1 to 53 or 107 to 254 disclosed herein, or variants and fragments thereof, or supplements thereof, wherein a decrease in expression of one or more of the Target pest sequences control the pest and pest population by insect sterilization (ie male and female sterility, reduced sperm count, egg production and viability) and sterile mating-based 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 disclosed. This summary is intended to be a screening tool for research purposes in the particular art and is not intended to limit the present invention.
