Two granulosis viruses (GV) were tested as enhancers for the gypsy moth nuclear polyhedrosis virus (LdMNPV). Helicoverpa armigera (Hübner) CV (HaGV) had no detrimental effect upon larval growth and development, but in combination with LdMNPV it reduced both the LC50 and the LT50 for the NPV. In addition, the combination also adversely affected the growth and development of gypsy moth larvae. The LC50 of LdMNPV was reduced by as much as 300-fold (HaGV at 10(-2) dilution) and the LT50 was reduced by as much as 18% (HaGV at 10(-2) dilution). Spodoptera frugiperda (J. E. Smith) GV reduced the LC50 of LdMNPV by as much as 13-fold but had no effect upon the LT50.
两种颗粒体病毒（GV）被作为舞毒蛾核型多角体病毒（LdMNPV）的增效剂进行了测试。棉铃虫（Hübner）颗粒体病毒（HaGV）对幼虫生长发育没有不利影响，但与LdMNPV联合使用时，它降低了NPV的半数致死浓度（LC50）和半数致死时间（LT50）。此外，这种组合也对舞毒蛾幼虫的生长发育产生了不利影响。LdMNPV的LC50降低了多达300倍（HaGV稀释至10(-2)），LT50降低了多达18%（HaGV稀释至10(-2)）。草地贪夜蛾（J. E. Smith）颗粒体病毒使LdMNPV的LC50降低了多达13倍，但对LT50没有影响。
