黑肩绿盲蝽Cyrtorhinus lividipennis(Reuter)是白背飞虱Sogatella furcifera(Horvath)卵期的一种重要捕食性天敌。为了摸清二者间数量变化关系,作者于1989年9～10月在实验室条件(25℃)下研究了黑肩绿盲蝽对白背飞虱的功能反应及干扰反应。现将研究结果简报如下:
Cyrtorhinus lividipennis (Reuter) is an important predatory natural enemy of the Sogatella furcifera (Horvath) egg stage of whitebacked planthopper. In order to find out the relationship between the quantity changes of the two species, the authors studied the functional responses and interference responses of the black-shouldered Apolygus lucorum on whitebacked planthopper, Siphonfemi, in laboratory conditions (25 ℃) from September to October 1989. Now the research findings are as follows:
