A natural antibacterial and antiviral biological composition is provided for use in hospitals and homes, in particular a composition that includes ricinoleic acid derived from the extraction of castor oil, diethanolamine and propolis, a method for obtaining the composition, and the use thereof. The invention can be used to control various pathogenic microorganisms, such as bacteria belonging to the Staphylococcus, Pseudomonas, Enterobacter and Bacillus genera; as well as hospital-environment fungi (filamentous and yeast-like) and phytopathogenic fungi (Colletrotichum fragariae). The product can be sprayed on biotic and abiotic surfaces, and non-woven fabric can subsequently be used to remove organic matter, including microorganisms. The product can also be used to disinfect medical, dental and hospital items by immersion followed by quick rinsing.

Compositions having pesticidal activity and methods for their use are provided. Compositions include isolated and recombinant polypeptide sequences having pesticidal activity, recombinant and synthetic nucleic acid molecules encoding the pesticidal polypeptides, DNA constructs comprising the nucleic acid molecules, vectors comprising the nucleic acid molecules, host cells comprising the vectors, and antibodies to the pesticidal polypeptides. Nucleotide sequences encoding the polypeptides provided herein can be used in DNA constructs or expression cassettes for transformation and expression in organisms of interest, including microorganisms and plants. The compositions and methods provided herein are useful for the production of organisms with enhanced pest resistance or tolerance. Transgenic plants and seeds comprising a nucleotide sequence that encodes a pesticidal protein of the invention are also provided. Such plants are resistant to insects and other pests. Methods are provided for producing the various polypeptides disclosed herein, and using those polypeptides for controlling or killing a pest.

This disclosure concerns the metabolic engineering of microorganisms to provide biosynthetic methods for the production of insect pheromones and precursors thereof in a scalable and eco-friendly fermentation reaction; for example, by converting saturated or unsaturated substrate feedstocks utilizing exogenous metabolic machinery.

An isolated polynucleotide includes: (a) a polynucleotide sequence as shown in SEQ ID NO: 1; or (b) a polynucleotide sequence having at least 15, 17, 19 or 21 contiguous nucleotides of SEQ ID NO: 1, wherein the growth of a pest of the order Coleoptera is inhibited when the pest of the order Coleoptera ingests double-stranded RNA comprising at least one strand that is complementary to the described polynucleotide sequence; or (c) any polynucleotide sequence as shown in SEQ ID NO: 3 to SEQ ID NO: 6; or (d) a polynucleotide sequence which hybridizes under stringent conditions with the polynucleotide sequence as defined in (a), (b) or (c). A plurality of target sequences are used for controlling a target gene c4506 of Monolepta hieroglyphica, which is a pest of the order Coleoptera.

A nucleotide sequence is shown in SEQ ID NO.1. The gene encodes mannosyltransferase I. The gene plays an important role in the normal reproductive development of the Nilaparvata lugens (Stål). Inhibition of the function of the gene may reduce the survival rate of the Nilaparvata lugens (Stål) and hinder embryonic development. With respect to reduction of the survival rate of the Nilaparvata lugens (Stål) and hindering of embryonic development, the present invention can reduce the harm of the Nilaparvata lugens (Stål) to rice by killing the Nilaparvata lugens (Stål). By using the characteristic that the nucleotide sequence of a highly conserved target gene has no homology with the nucleotide sequence of natural enemies of the Nilaparvata lugens (Stål), RNA interference is performed at a nucleic acid level, to avoid the harm to non-target organisms such as natural enemies, thereby realizing green control of the Nilaparvata lugens (Stål) while controlling pests.

Compositions for attracting and/or trapping male agricultural pests, particularly Spodoptera species (e.g., fall armyworm) are described. The compositions comprise two active components, one comprising a C7-C11 aldehyde and one comprising a C12-C16 aldehyde, acetate ester or primary alcohol. Also described are devices for attracting and/or trapping the agricultural pests and methods of controlling the population of the agricultural pests.
