我组多年来探索饲养玉米螟的半人工饲料,目前巳取得一些初步结果:用天然螟卵为材料繁殖一代螟虫,可获得幼虫成活率高(80—100％)、发育进度整齐,正常羽化率达80％左右,雌雄比约1:1.5,并能产下较多的受精卵。 目前的饲料只用于繁殖一代螟虫(下一代如何需进一步观察),作为螟虫的药效测定或不同温湿度条件对螟虫的影响等试验之用还是可以的。 一、饲料的配方 以100毫升水作为一个配方单位。 Our group has explored the semi-artificial feed for feeding corn borer for many years. At present, some preliminary results have been obtained: the survival rate of the larvae is high (80-100%), the development progress is neat, the normal emergence rate Up to 80%, about 1: 1.5 male and female, and can produce more fertilized eggs. The current feed is only used to breed a generation of stem borers (how to further observe the next generation), as the efficacy of stem borers measured or different temperature and humidity conditions on the effects of stem borers and other tests still use. A feed formula with 100 ml of water as a formula unit.
