Wheat red spider is an infrequent pest of wheat fields in our city. There are three kinds of wheat spiders. There are mainly two types of wheat spiders in our city: wheat spider spider and wheat leg spider. Maiyuan spiders occur in mooring areas, and wheat long leg spiders occur in hilly and hilly lands. Both kinds of spiders can suck wheat leaf sap from the wheat seedling stage to the heading stage, showing yellow and white spots on the leaves, gradually yellowing the leaves, and causing the whole wheat pieces to die.
As the temperature rises, the population density of wheat spider mites will increase. Therefore, the city plant protection personnel recommended that the majority of farmers attach great importance to it, and prepare enough medicines. If the red spider 100/city foot is single, it should pay attention to prevention and control.
