Description

technical field

[0001] The invention belongs to the technical field of agricultural microbiology, and in particular relates to a protein BVP10 for preventing and controlling spider mites and its application. Background technique

[0002] Spider mite, also known as red spider mite, spider mite (spider mite), is a plant-eating mite of the subclass Acarina (Acarina) Tetranychidae (Tetranychidae). Feeds on leaves and fruit of houseplants and important agricultural plants, including fruit trees. The life of spider mites goes through five stages: eggs, larvae, early nymphs, late nymphs, and adults, and it takes about 3 weeks from egg to adult. The life cycle of spider mites is short, and they reproduce rapidly. Generally, one generation can be completed in a few to ten days, and several to ten generations can be completed in one year. They often cause extremely serious damage to crops. Adult mites are about 0.5 mm long, with red, green or brown bodies, and form a loose silk net ...
