Bioassay of PoNPV+1%TinopalLPW was conducted on second instar larvae of a laboratory colony of Parocneria orienta. The results showed that 1%TinopalLPW had a marked synergistic effect. Various doses of PoNPV along with 1%TinopalLPW were sprayed on second and third instar larvae of an overwintering population in the field. The combinations were 3.6×1011PIB/hm2+1%TinopalLPW, 1.8×1011PIB/hm2+1%TinopalLPW, 9.0×1010PIB/hm2+1%TinopalLPW and 3.6×1011PIB/hm2, 1.8×1011PIB/hm2, 9.0×1010PIB/hm2. The most marked synergistic effect was obtained with 9.0×1010PIB/hm2+1%TinopalLPW. Other combinations did not have significant synergistic effects.
