The invention relates to an agricultural biological control technology, and aims to provide a brevundimonas strain and application thereof in degradation of
dinotefuran and improvement of resistance. The brevundimonas sp. Strain is preserved in the China Center for Type Culture Collection, the preservation name is brevundimonas sp. D-1, the Latin name is Brevundimonas huaxiensis, and the preservation number is CCTCC NO: M 20252463. The brevundimonas sp. Strain has the advantages that the brevundimonas sp. Strain can be used for preparing the brevundimonas sp. The 16S rRNA
gene sequence of the strain is as shown in SEQ ID NO: 1. The strain disclosed by the invention is novel in source, has functional specificity and pertinence, and shows remarkable degradation capacity on
dinotefuran; the
intrinsic resistance of the parasitic wasps to
dinotefuran can be improved through back-supplementing the strains; microorganisms are used for degradation and biological enhancement, so that secondary
pollution is avoided, and the method conforms to the development direction of modern
agriculture.
