Oxycarenus hyalinipennis Costa is a polyphagous insect pest and can develop insecticide resistance. The resistance of O. hyalinipennis to neonicotinoids (clothianidin and dinotefuran), flonicamid, and conventional insecticides; carbamates (methomyl and carbosulfon), organophosphates (chlorpyrifos and malathion), and pyrethroids (cypermethrin and zeta-cypermethrin) was evaluated. The O. hyalinipennis populations were sampled from four locations in Pakistan and performed bioassays against the insecticides by leaf dip protocol. The O. hyalinipennis' populations showed low resistance to carbosulfan (resistance ratio (RR) = 2.06-6.34) and methomyl (RR = 2.78-7.27), moderate to high resistance to chlorpyrifos (RR = 30-45), malathion (RR = 20.29-88.19), and flonicamid (RR = 14.24-46.97), in comparison with the susceptible strain. Susceptibility to low resistance against cypermethrin (RR = 1.27-2.82), zeta-cypermethrin (RR = 2.62-3.38), and clothianidin (RR = 1.74-3.40), and low to moderate resistance to dinotefuran (RR = 3.84-13.43) in the field populations, was observed compared to the susceptible strain. A rotational usage of carbamates and pyrethroids with an integrated pest management tool should be considered to deal with O. hyalinipennis' insecticide resistance.
透翅莹叶甲 Costa 是一种多食性害虫，能够产生抗药性。本研究评估了透翅莹叶甲对新烟碱类（噻虫嗪和呋虫胺）、氟啶虫酰胺、以及传统杀虫剂（灭多威和涕灭威）、氨基甲酸酯类（灭多威和涕灭威）、有机磷类（毒死蜱和马拉硫磷）和拟除虫菊酯类（氯氰菊酯和 zeta-氯氰菊酯）的抗性。从巴基斯坦的四个地点采集了透翅莹叶甲种群，并通过叶浸法进行了生物测定。结果表明，透翅莹叶甲种群对涕灭威（抗性比（RR）=2.06-6.34）和灭多威（RR=2.78-7.27）的抗性较低，对毒死蜱（RR=30-45）、马拉硫磷（RR=20.29-88.19）和氟啶虫酰胺（RR=14.24-46.97）的抗性为中至高，与敏感品系相比。与敏感品系相比，田间种群对氯氰菊酯（RR=1.27-2.82）、zeta-氯氰菊酯（RR=2.62-3.38）和噻虫嗪（RR=1.74-3.40）的抗性较低，对呋虫胺（RR=3.84-13.43）的抗性为低至中等，与敏感品系相比。应考虑使用氨基甲酸酯类和拟除虫菊酯类杀虫剂与综合害虫管理工具相结合，以应对透翅莹叶甲的抗药性问题。
