Nucleopolyhedrosis viruses can be utilized for effective management of agriculture pests. Their efficacy can be increased if they are mixed with certain insecticides. In the current study, HaNPV was mixed with two insecticides: spinetoram and emamectin benzoate in various combinations and applied to larvae of H. armigera in laboratory conditions. There were a total of 15 combinations of HaNPV with each of the two insecticides in addition to five doses of HaNPV and three doses of insecticides alone. The synergistic and antagonistic effects of combinations were explored. The results revealed that there was synergistic effect of HaNPV @ 0.5 × 109 PIB/ml × Spinetoram @ 40, 20, 10 ml/100 L of water. In case of emamectin benzoate, synergistic effects were recorded at 1 × 109 PIB/ml HaNPV × emamectin benzoate @ 100 ml/100 L of water. However, 0.5 × 109 PIB/ml HaNPV has synergistic effects with all three doses of emamectin benzoate. The results suggested that HaNPV can be used in combination with spinetoram and emamectin benzoate for the management of resistant population of H. armigera.

HaNPV与两种新型杀虫剂对棉铃虫Hubner(Noctuidae:鳞翅目)的相互作用。

核多角体病毒可用于有效控制农业害虫。如果将它们与某些杀虫剂混合使用,则可以提高其功效。在当前的研究中,HaNPV与两种杀虫剂混合存在:各种形式的多杀菌素和苯甲酸酯联苯甲酸酯,并在实验室条件下应用于棉铃虫的幼虫。除五剂HaNPV和三剂杀虫剂外,总共有15种HaNPV与两种杀虫剂中的每一种的组合。探索了组合的协同和拮抗作用。结果表明,HaNPV @ 0.5×10 9 PIB / ml×Spinetoram @ 40、20、10 ml / 100 L的水具有协同作用。对于苯甲依莫菌素,在1×10 9处记录到协同作用PIB / ml HaNPV×苯甲依氨菌素@ 100 ml / 100 L的水。但是,0.5×10 9 PIB / ml HaNPV与所有三种剂量的依那莫汀苯甲酸酯都具有协同作用。结果表明,HaNPV可以与菠菜乙酰胺和苯氨连菌素联用用于防治棉铃虫的耐药种群。
