高粱蚜[Meeanaphio Aacchari(Zehntner)]在张家口地区主要危害高粱,在适宜条件下形成毁灭性的危害,近10年来在1972、1975和1980年有三次大发生。1975年据估计全地区因高粱蚜危害减产粮食一亿斤左右。据此自1978年确立本课题,研究高粱蚜的发生规律,为找出安全、经济有效的防治方法提供依据。在研究中明确了以下几个问题:
The sorghum aphid [Meeanaphio Aacchari (Zehntner)] is a major hazard to sorghum in the Zhangjiakou area and forms a devastating hazard under appropriate conditions. Three major occurrences occurred in 1972, 1975 and 1980 in the past decade. In 1975, it is estimated that the entire region will lose about 100 million kilograms of grain due to the damage caused by the sorghum aphid. Based on this, this subject has been established since 1978 to study the occurrence of sorghum aphids and provide a basis for finding safe, economical and effective methods of prevention and treatment. In the study made clear the following questions:
