The invention relates to a composite microbial fertilizer for controlling crop diseases and insect pests, which contains composite microbial fungicide and is prepared by the following raw materials based on parts by weight: 10-35 parts of composite microbial fertilizer fungicide, 3-15 parts of composite microbial pesticide fungicide, 1-5 parts of insecticidal synergist, 1-5 parts of plant growth regulator, 20-60 parts of grass carbon, 5-15 parts of expanded chicken manure, 5-50 parts of inorganic fertilizer and 1-3 parts of binding agent, wherein the composite microbial fertilizer fungicide is prepared by bacillus megaterium and jelly-like bacillus; and the composite microbial pesticide fungicide is prepared by mixing bacillus thuringiensis and bacillus subtilis, adding sodium percarbonate type solid state oxygen-increasing agent for mixing and fermenting and finally absorbing by the grass carbon. The composite microbial fertilizer adopts strains with good suitability, and the strains are compounded according to a certain proportion to obtain the composite fungicide which has durable activity and stable performance; and the four beneficial strains are compatible with each other and performs the own functions, so that the multiple aims of resisting germs as well as diseases and insect pests, and increasing the crop yield can be achieved.

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: 1-236 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 D. virgifera virgifera, D. barberi, D. speciosa, or D. undecimpunctata howardi. 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.
