以往生产毒蝇纸是用面粉、红糖和敌百虫作原料。红糖来源较缺,成本较高,使基层社队大量生产受到一定限制。我们试用了西瓜汁代替红糖生产毒蝇纸,收到了很好的效果。西瓜汁的提取:选择熟西瓜去皮后放纱布中挤出全部汁水,将汁水放锅中煮沸稍浓缩即可。毒蝇纸的制作:把浓缩的西瓜汁趁热和面粉按2:1 Past production of fly paper is to use flour, brown sugar and trichlorfon as raw material. Scarce sources of brown sugar, higher costs, mass production of grassroots communes and brigades subject to certain restrictions.

Extraction of watermelon juice: Choose cooked watermelon peeled and then put all the juice out of gauze juice, put the juice in the pan boiling slightly concentrated can. Dust fly paper production: the concentrated watermelon juice while hot and flour by 2: 1
