The present invention relates to control of pest infestation by inhibiting one or more biological functions. The invention provides methods and compositions for such control. By feeding one or more recombinant double stranded RNA molecules provided by the invention to the pest, a reduction in pest infestation is obtained through suppression of gene expression. The invention is also directed to methods for making transgenic plants that express the double stranded RNA molecules, and to particular combinations of transgenic pesticidal agents for use in protecting plants from pest infestation.

Compositions and methods for controlling pests are provided. The methods involve transforming organisms with a nucleic acid sequence encoding an insecticidal protein. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest including plants, as probes for the isolation of other homologous (or partially homologous) genes. The pesticidal proteins find use in controlling, inhibiting growth or killing Lepidopteran, Coleopteran, Dipteran, fungal, Hemipteran and nematode pest populations and for producing compositions with insecticidal activity.

The subject invention relates to the surprising discovery that toxin complex (TC) proteins, obtainable from Xenorhabdus, Photorhabdus, and Paenibacillus, can be used interchangeably with each other. In particularly preferred embodiments of the subject invention, the toxicity of a “stand-alone” TC protein (from Photorhabdus, Xenorhabdus, or Paenibacillus, for example) is enhanced by one or more TC protein “potentiators” derived from a source organism of a different genus from which the toxin was derived. As one skilled in the art will recognize with the benefit of this disclosure, this has broad implications and expands the range of utility that individual types of TC proteins will now be recognized to have. Among the most important advantages is that one skilled in the art will now be able to use a single set of potentiators to enhance the activity of a stand-alone Xenorhabdus protein toxin as well as a stand-alone Photorhabdus protein toxin. (As one skilled in the art knows, Xenorhabdus toxin proteins tend to be more desirable for controlling lepidopterans while Photorhabdus toxin proteins tend to be more desirable for controlling coleopterans.) This reduces the number of genes, and transformation events, needed to be expressed by a transgenic plant to achieve effective control of a wider spectrum of target pests. Certain preferred combinations of heterologous TC proteins are also disclosed herein. Other objects, advantages, and features of the subject invention will be apparent to one skilled in the art having the benefit of the subject disclosure.

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. speciosa, or D. undecimpunctata howardi. 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.

A pest and disease modeling framework for precision agriculture applies weather information, pest biological characteristics, and crop management data to anonymous crowd-sourced observations of pest presence for a reporting field. A risk assessment profile of pest occurrence for targeted fields in proximity to reporting fields is modeled to generate field-specific measures for pest management of pest infestation. The pest and disease modeling framework matches and filters weather and crop information in infested and pest-free fields based on the anonymous, crowd-sourced reporting of an existing pest presence, by evaluating similarities in pest-relevant data. Fields that are similar to infested fields have the highest risk of infestation, and the modeling framework provides output data in the form of a prediction of pest occurrence based on the risk assessment profile.
