| 摘 要： | 通过多年调查和试验研究，弄清了本市稻田主要捕食性天敌蜘蛛和黑肩绿盲蝽在不同时期的发生规律，明确了天敌对褐飞虱的控制作用，其中以７月下旬至８月中旬和９月中旬以后最为明显；当蛛虱比或蝽虱比值小于２时，蜘蛛、黑肩绿盲蝽即能有效地控制前期稻飞虱的危害，为制定中粳稻区综合治理褐飞虱策略提供了理论依据。

| Abstract: | The dynamics of the main predacious natural enemies such as spiders and black shouldergreen bug in paddy field was investigated in the past several yeare. The control effects are most ob-vious in the Period from the last July to the middle August and after the midddle September. Whilethe radio of spiders to brown planthopper or the radio of bug to planthopper is less than 2, spidersand blackshoulder green bug can effechvely control the injury of brown planthopper in earier stage.This is the theoretical base of the tactics for integrated control planthopper in the median semi-gluti-nous nce growing zone. |
