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.

The invention provides a method for artificially feeding ladybirds and / or lacewings. The method comprises the following steps of: (1) incubating lepidoptera insect larvae after lepidoptera insect adults lay eggs, and feeding the lepidoptera insect larvae with feed; (2) feeding ladybird larvae and / or lacewing larvae by using the lepidoptera insect larvae as feed to obtain ladybird adults and / or lacewing adults, wherein the lacewings are selected from one of chrysopa septempunctata and chrysoperla nipponensis; and (3) feeding the ladybird adults and / or chrysopa septempunctata adults by using the lepidoptera insect larvae as the feed, and feeding chrysoperla nipponensis adults by using honey and beer dry yeast powder. Compared with the prior art, the method for feeding the ladybirds and the lacewings in a large scale by using the lepidoptera insect larvae as the feed replaces the conventional method for feeding the ladybirds and the lacewings which are natural enemies of aphids by using the aphids cultured by plants, and the method saves more time and labor, is simpler and more convenient and is easier to operate.
