【摘要】 用1%TinopalLPW荧光增白剂作为蜀柏毒蛾核型多角体病毒增效剂对蜀柏毒蛾2龄幼虫进行室内毒力测定,结果表明1%TinonalLPW对ParocneriaorientaNPV有较强的增效作用。使用3.6×1011PIB/hm2+1%TinopalLPW、1.8×1011PIB/hm2+1%TinopalLPW、9.0×1010PIB/hm2+1%TinopalLPW和3.6×1011PIB/hm2、1.8×1011PIB/hm2、9.0×1010PIB/hm26种处理对林间越冬代2-3龄幼虫进行超低容量喷雾防治,结果表明除9.0×1010PIB/hm2+1%TinopalLPW表现出显著的增效作用外,其余剂量有增效作用但不显著。更多还原

【Abstract】 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.更多还原
