为了减轻和控制棉铃虫的发生量,1971年我们在棉区推广了一万多盏黑光灯,经过一、二年的实践,在农业科技人员和部分领导干部中出现了两种观点:一种认为使用黑光灯利多弊少,效果很好;另一种则刚刚相反。为了弄清楚这个问题,我们于1973—1974年结合蹲点工作,在九江县江洲公社洲头大队对7,000多亩棉地使用黑光灯的情况,作了系统的调查,并作了一些试验研究,现整理报告如下。 关于黑光灯诱虫效果问题,根据我们1973年和1974年在两盏20瓦黑光灯下的记载,平均每年每盏灯诱杀了棉铃虫蛾7940.5只、金钢钻835.5只、小地老虎170只、红铃虫39.5只、其他棉花害虫2,640只。由此可见,黑光灯不仅能诱灭大量的棉铃虫蛾子,而且可诱歼大批的其他棉花害虫。
In order to reduce and control the occurrence of cotton bollworm, we promoted more than 10,000 black light bulbs in the cotton area in 1971. After one or two years of practice, two opinions emerged among agricultural scientists and technicians and some leading cadres: I think the use of black light more advantages and disadvantages, the effect is good; the other is the opposite. In order to clarify this issue, we conducted a systematic investigation into the use of black light bulbs in 7,000 mu of cotton land in Chau Tze Chau, Jiujiang County in 1973-1974 in conjunction with the dwelling hours, and conducted some experimental studies. Finishing report is as follows. On the issue of black light trap effect, according to our 1973 and 1974 records under two 20-watt black light bulbs, average of 7940.5 bollworm moths, 835.5 golden diamonds, 170 small tigers , 39.5 pink bollworm and 2,640 other cotton pests. This shows that black light can not only induce a large number of bollworm moths, but also induce a large number of other cotton insect annihilate.
