黑光灯是目前诱杀成虫、研究成虫活动规律进行预测预报不可缺少的工具。在我们使用的过程中,发现还有不少缺点需要改进。如雨夜不能诱蛾,通夜诱测常因害虫过多,造成挤压失征不易分辨,次日查虫费工等。为提高黑光灯的应用效能,系统完整地积累资料,我们在禹城气候站的协助下,1964年6月18日-7月28日对黑光灯进行了改装。改装后,经汛期和昆虫活动盛期(8-10月)试用的结果,效果良好。现将改装方法和使用的效果介绍于下。一、改装方法:原有黑光灯的支架、灯身、漏斗均不变,仅将诱集筒进行改装。(1)筒上增加直径30-32厘米、高4厘米、中心孔直径5厘米的伞形盖一个。(2)筒底安装漏水调节装置。此装置由三部分组成,即目径0.2厘米的漏水孔,长4厘、宽0.8厘米的漏水闸和把手。(3)增加直径20-32厘米、深3-5厘米、目径0.5厘米的铁筛子一个。(4)增加高18-20厘米、
Black light is currently trapping adults, the law of activity of adults for forecasting an indispensable tool. In our use of the process, we found that there are still many shortcomings need to be improved. Such as rainy night can not be induced moths, night-long induction often due to excessive pests, resulting in difficult to distinguish between the extrusion loss of symptoms, check the worm the next day and so on. In order to improve the application efficiency of black light, the system accumulates data completely. With the help of Yucheng Climate Station, the black light was modified from June 18 to July 28, 1964. After modification, after the flood season and insect activity peak (August-October) trial results, the effect is good. Now modified methods and the use of the effect introduced below. First, the conversion method: The original black light bracket, lamp body, funnel are not changed, only the trapping tube modification. (1) increase the tube diameter 30-32 cm, 4 cm high, the center hole diameter of 5 cm umbrella cover a. (2) the bottom of the tube installation of water leakage control device. The device consists of three parts, namely, the diameter of 0.2 cm leak hole, 4 cm long and 0.8 cm wide drain and handle. (3) increase the diameter of 20-32 cm, 3-5 cm deep, diameter 0.5 cm iron sieve one. (4) increase the height of 18-20 cm,
