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 &#x3bc;g/mL against, a median lethal concentration of 58.05 &#x3bc;g/mL against, a median lethal concentration of 36.08 &#x3bc;g/mL against, and a control effect of 79.53%-95.45% against strawberry red spider mites. The protein is provided for preparing a novel mite pesticide.

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 &#x3bc;g/mL against, 33.45 &#x3bc;g/mL against, and 26.32 &#x3bc;g/mL against, and shows an inhibitory effect against the hatching and cleavage ofeggs, with the egg cleavage rate of 75.86% after 72 h. The protein provides a new option for the preparation of a novel miticide.

By determining the lethality rate toand, it was found that the methylmalonic acid has a better nematicidal effect on the, with the LCbeing 13.11 and 1.20 for theand the, respectively. After compounding the methylmalonic acid with betaine, the LCwas 2.85 and 0.27 for theand the, respectively. Meanwhile, the methylmalonic acid also has an inhibiting effect onand. The preparation of the methylmalonic acid provides a new choice for preparing novel biocontrol agents against the root-knot nematodes.
