在深入批林批孔运动的大好形势推动下,我们因陋就简、以土代洋进行了红铃虫性诱剂的粗提和使用,取得了初步结果。 1.收集虫源 1.在收花晒花时,收集老熟雌性幼虫(腹背面无隐现的睾丸体),装入试管任其结茧越冬,到第二年3月放进土温箱加温(27-28℃),盖上湿布调节湿度,促使整齐化蛹。2.在4月下旬至5月上旬,从吊籽花里检蛹,每支试管放3-5头雌蛹(腹部末端生殖器部位的腹节呈两个“人”字形),任其自然羽化。 2.提取性诱剂粗提物 在成虫羽化期间,连续进行三天光照处理,每天光照22小时(白天用自然光照,夜晚用煤油灯照),黑暗2小时。在第三天黑暗2小时后,剪取雌蛾腹部末端三节,浸入二氯甲烷溶剂中,待全部雌蛾剪尾浸入后,一起倒进研钵,捣碎成浆糊状, On the basis of the excellent situation of going through the forestation of bark and bore hole, we got the preliminary results because of the simple procedure and the crude extraction and use of the red bollworm lures by the soil. 1. Collection of insect source 1. In the flower sunflowers, the collection of mature female larvae (Abdominal abdomen without loss of testicular body), into the test tube any of its cocoon overwintering into the second year in March Tuoteng plus Temperature (27-28 ℃), covered with damp cloth to regulate humidity, to promote neat pupation. 2. In late April to early May, pupae were picked from hanging flower seeds, and 3-5 female pupae were placed in each test tube (the abdomen of abdomen genital part showed two “human” glyphs) . Extract lure crude extract during the emergence of adults, three consecutive days of light treatment, light 22 hours a day (with natural light during the day and night with kerosene lamps according to), dark for 2 hours. Two days after the darkness on the third day, three sections of the abdomen of the female moths were cut and immersed in a methylene chloride solvent. After all the female moths were dipped and dipped into the mortar, the mixture was poured into a mortar,
