在毛主席革命路线指引下,我所批林批孔运动有力地促进了科研工作的开展,1974年在扩大繁殖赤眼蜂防治松毛虫的同时,初步进行了一次土法提取马尾松毛虫性引诱剂的诱蛾试验。现将方法与效果整理如下: 1.性引诱剂粗提物的提取 采集松毛虫茧,剖茧取雌蛹于室内常温下保护(20-35℃,相对湿度50-8O％),待自然羽化后,每天上、下午六点各收蛾一次,次日早上2-5点剪取雌蛾腹部末端三节,用捣筒捣碎成泥状,泡浸于二氯甲烷中,置10℃以下冰箱保存24小时,第三天早上5点前 Under the guidance of Chairman Mao’s revolutionary line, the campaign I approved by Lin and Kong dynasty vigorously promoted the development of scientific research. In 1974, while expanding the breeding of Trichogramma dendrolimi against Plutella xylostella, Agent moth test. Now the method and effect are summarized as follows: 1. Sex attractant extract extract pine dendritic cocoon, cut the cocoon take female pupae at room temperature to protect (20-35 ℃, relative humidity 50-8O%) to be natural emergence After every day, at 6 o’clock in the afternoon each moth once, the next morning 2-5 points to cut the moth abdominal end of three sections, crushed with a mash into mashed, soaked in methylene chloride, set the refrigerator below 10 ℃ Save 24 hours, the third day before 5 o’clock in the morning
