黑光灯诱测成虫是一项辛苦、细致的病虫害预测工作，如何改进装置，实现自控，减少工作量，有人曾报道“用光导体实现黑光灯的自控”，使黑光灯在白天有光时线路断开熄灭；夜间无光线路闭合发亮。在长期的实践中，笔者利用普通闹钟改进了黑光灯自控装置，方法简便易行，现介绍 Black light induction adult is a hard and meticulous pest prediction work, how to improve the device, to achieve self-control, reduce workload, it was reported that “the use of light conductor to achieve black-light control” so black light in the daylight when the line Off off; no light at night closed the circuit light. In the long-term practice, I use the ordinary alarm clock to improve the black light automatic control device, the method is simple and easy, are introduced
