1978—1981年,从不同作物的不同部位作饲料喂养玉米螟幼虫,观察其对各虫态生长发育的影响,同时探讨了不同饲料糖分、蛋白质含量在营养上的作用,现将结果整理如下。 一、试验材料与方法 (一)、幼虫饲养 将不同饲料的不同部位置于粗指管(1.7×7.5cm)。接虫后加棉塞。 1.玉米饲料 一至四代的一、二龄蚁螟喂嫩叶,三龄后喂嫩茎或老茎或嫩果穗。1981年分别用皋单一号(中早熟种)、丹王六号(中熟种)、 In 1978-1981, the corn borer larvae were fed from different parts of different crops to observe their effects on growth and development of each insect state. At the same time, the effect of different feedstuff sugar and protein content on nutrition was discussed. The results are summarized as follows. First, the test materials and methods (A), larvae feeding Different parts of different feed placed in the rough tube (1.7 × 7.5cm). After adding worms tampons. 1. Maize feed one to four generations of the first and second instar insects feeding young leaves, after the third age to feed young stems or old stems or tender ear. 1981, respectively, with a single high (middle-early maturing), Dan Wang VI (medium-mature),
