红蜘蛛是我县棉花上的重要害虫之一。近年来,由于耕作制度的改变,红蜘蛛由过去的轻发型逐步变成重发型,常年有40％左右棉田面积红叶,0.5％左右面积掉叶,严重地影响着棉花早熟丰产。1975年以来,我们在测报和防治中作了些调查研究,使我们对红蜘蛛发生规律和防治问题的认识较前提高了一步。 Red spider is one of the important pests on cotton in our county. In recent years, due to the change of tillage system, red spiders have gradually changed from the light hair style to the re-hair style, perennial about 40% of the red leaves of cotton fields and about 0.5% of the area of ​​leaf leaves seriously affect the cotton precocious yield. Since 1975, we have made some investigations in the field of forecasting and prevention so as to make our understanding of the regularity and prevention and control of spider mites one step further.
