摘  要：
[目的]研究亚致死浓度氟啶虫胺腈对中黑盲蝽发育和繁殖的影响,分析亚致死浓度处理下中黑盲蝽对其他药剂的敏感性变化.[方法]采用生命表法,研究亚致死浓度氟啶虫胺腈处理对中黑盲蝽发育历期、羽化率、寿命和产卵的亚致死效应;采用浸渍法,测定亚致死浓度氟啶虫胺腈处理下中黑盲蝽对其他药剂的敏感性.[结果]经LC10和LC25氟啶虫胺腈处理,中黑盲蝽3~5龄若虫历期分别比对照显著延长2.35和4.19 d,产卵前期分别比对照显著延长3.6和4 d,单雌产卵量分别比对照显著减少了11.93和13.23粒.经氟啶虫胺腈LC10和LC25处理,吡虫啉、呋虫胺、高效氯氟氰菊酯3种杀虫剂的LC50在CK对照组中分别为187.18、506.35和153.22 mg/L,在LC10处理组中分别为134.15、370.99和111.15 mg/L,在LC25处理组中分别为86.90、271.15和97.60 mg/L.中黑盲蝽受氟啶虫胺腈亚致死浓度LC10和LC25处理,对吡虫啉、呋虫胺、高效氯氟氰菊酯3种杀虫剂的敏感性均增加.[结论]氟啶虫胺腈亚致死浓度处理使中黑盲蝽发育迟缓且繁殖力降低,亚致死浓度处理增加中黑盲蝽对吡虫啉、呋虫胺、高效氯氟氰菊酯的敏感性.

摘  要：
【Objective】 The mirid bug Adelphocoris suturalis(Hemiptera: Miridae) is an important insect pest of cotton. The present study aims to determine the sublethal effects of sulfoxaflor on the development and reproduction of this insect and its susceptibility to other insecticides.【Methods】The life table method was used to evaluate the effects of sublethal concentrations of sulfoxaflor on developmental duration, emergence rate, longevity and reproduction of A. suturalis. The cotton leaf dipping method was adopted to determine its susceptibility to other insecticides after sublethal concentrations of sulfoxaflor treatments.【Results】The developmental duration of A. suturalis treated with sublethal concentrations(LC_(10) and LC_(25)) of sulfoxaflor for 48 h was significantly increased by 2.35 d and 4.19 d, the preoviposition period was greatly increased by 3.6 d and 4 d, and average egg number of per female was significantly decreased by 11.93 and 13.23 as compared with the control. The susceptibility of sulfoxaflor-treated A. suturalis to imidacloprid, dinotefuran and cypermethrin showed that the LC_(50 )values of the three chemicals were 187.18, 506.35 and 153.22 mg/L in CK group, and 134.15, 370.99 and 111.15 mg/L in LC_(10 )treatment group, and 86.90、271.15和97.60 mg/L in LC_(25) treatment group, respectively. The relative toxicity index(RTI) of imidacloprid, dinotefuran and cypermethrin to A. suturalis indicated that the susceptibility of sulfoxaflor-treated A. suturalis to these three insecticides was increased.【Conclusion】Sulfoxaflor at sublethal concentrations can reduce the fecundity and population growth of A. suturalis and make it more susceptible to imidacloprid, dinotefuran and cypermethrin.
