使用该实验室开发的化学成分确定的饲料 D-97 实现了褐飞虱 Nilaparvata lugens (Stal) 的连续饲养。用 D-97 饲养的褐飞虱的性能比以前报道的人工饲料 MMD-1 饲养的要好得多，尽管它不如易感水稻品种 TN1。由于繁殖力差、卵无法孵化，褐飞虱在MMD-1上无法完成完整世代，但在D-97上已成功饲养6代以上。与TN1饲养的褐飞虱相比，D-97饲养的昆虫若虫期更长（雄性延长3天以上，雌性延长5天以上），雄性体重较轻，雄性轻25%，雌性轻35%），繁殖力较低的雄性昆虫轻50%）。在 D-97 的六代中，前两代的出苗率和孵化率明显较高。还讨论了影响饲养效率的可能因素以及该饲料的潜在应用。
Continuous rearing of the brown planthopper, Nilaparvata lugens (Stal), was achieved on a chemically defined diet D-97 developed in this laboratory. The performance of N. lugens reared on D-97 was much better than that on a previously reported artificial diet MMD-1, although it was inferior to the susceptible rice variety TN1. N. lugens can not finish a complete generation on MMD-1 due to poor fecundity and unhatchability of eggs, but it has been successfully reared for more than 6 generations on D-97. In comparison with TN1-reared N. lugens, D-97-reared insects had a longer nymphal period (more than 3 days longer for males and 5 days longer for females), lighter weight lover 25% lighter for males and 35% lighter for females) and lower fecundity lover 50% less). Of the six generations on D-97, the first two generations had a significantly higher rate of emergence and hatchability. The possible factors influencing rearing efficiency and the potential applications of this diet are also discussed.
