通过室内生物测定和野外试验，筛选出双线盗毒蛾ＮＰＶ－Ｂｔ－白僵菌复合杀虫剂的最佳组合为Ｂ１Ａ１Ｃ３，即Ｍ－Ｂｔ孢子５００亿个／Ｌ＋ＰｓＮＰＶＰＩＢ５×１０１０／Ｌ＋白僵菌孢子１０００亿个／Ｌ．复合杀虫剂中添加低浓度化学农药有明显增效作用，但对ＰｓＮＰＶ的传代不利．林间防治以隔行带状喷洒较好．
The best combination of NPV-Bt-Beauveria bassiana compound insecticide was B1A1C3, which was 50 M / L + PsNPVPIB5 × 1010 / L + Beauveria bassiana spores 100 billion / L. Compound pesticides to add low concentrations of chemical pesticides have a synergistic effect, but the PsNPV passage of the negative. Interforest prevention and control sprayed better interlaced band.
