Abstract: A BVP10 protein shown in SEQ ID NO:2 for controlling tetranychid mites and use of the protein is provided. The BVP10 protein has a median lethal concentration of 19.07 ?g/mL against Tetranychus urticae, a median lethal concentration of 58.05 ?g/mL against Panonychus citri, a median lethal concentration of 36.08 ?g/mL against Tetranychus cinnabarinus, and a control effect of 79.53%-95.45% against strawberry red spider mites. The protein is provided for preparing a novel mite pesticide.

Abstract: A BVP8 protein for killing tetranychid mites and use thereof are provided. The protein is as set forth in SEQ ID NO. 2. The BVP8 protein has a median lethal concentration of 12.98 ?g/mL against Tetranychus urticae, 33.45 ?g/mL against Panonychus citri, and 26.32 ?g/mL against Tetranychus cinnabarinus, and shows an inhibitory effect against the hatching and cleavage of Tetranychus urticae eggs, with the egg cleavage rate of 75.86% after 72 h. The protein provides a new option for the preparation of a novel miticide.

Abstract: By determining the lethality rate to Meloidogyne incognita and Caenorhabditis elegans, it was found that the methylmalonic acid has a better nematicidal effect on the Caenorhabditis elegans, with the LC50 being 13.11 and 1.20 for the Meloidogyne incognita and the Caenorhabditis elegans, respectively. After compounding the methylmalonic acid with betaine, the LC50 was 2.85 and 0.27 for the Meloidogyne incognita and the Caenorhabditis elegans, respectively. Meanwhile, the methylmalonic acid also has an inhibiting effect on Pseudomonas solanacearum and Erwinia carotovora. The preparation of the methylmalonic acid provides a new choice for preparing novel biocontrol agents against the root-knot nematodes.

Abstract: Strain of Bacillus thuringiensis novonest4 and applications thereof. The Bacillus thuringiensis is the Bacillus thuringiensis novonest4, with an Accession No. CCTCC NO: M2018443. The strain is firstly reported to have both the effect of preventing and controlling lepidoptera pests after foilar application and the effects of degrading carbendazim, promoting crop growth and increasing crop yield after soil application, and has wide application prospects in agricultural production.
