摘　　要：为改善蠋蝽在室内继代饲养过程中品质退化问题,提高该虫规模化繁殖效率。本研究以田间大纱笼作为半自然条件,对室内连续繁殖10代的蠋蝽4龄若虫进行复壮,并在室内条件下测定了复壮与未复壮蠋蝽交叉配对(♀_(田)×♂_(田)、♀_(田)×♂_(室)、♂_(田)×♀_(室)、♀_(室)×♂_(室))后的雌雄成虫寿命、繁殖能力、F1代发育历期及存活率等生物学特性。结果表明,复壮未对蠋蝽雌雄成虫寿命产生显著影响,但对其生殖力及F1代适应性等方面影响显著。♀_(室)×♂_(田)配对组的蠋蝽产卵量最高、产卵前期最短、产卵期最长;相较于雌虫未复壮组(♀_(室)×♂_(田)、♀_(室)×♂_(室)),雌虫复壮组(♀_(田)×♂_(田)、♀_(田)×♂_(室))的产卵量减少、产卵前期延长;雌雄虫未复壮组(♀_(室)×♂_(室))无明显偏雌或雄性现象,而雌雄虫均复壮或其中一方复壮组(♀_(田)×♂_(田)、♀_(田)×♂_(室)、♀_(室)×♂_(田))均出现明显偏雌性;相较于雌雄虫未复壮组,♀_(田)×♂_(田)的F1代由卵到成虫的发育期显著延长、成虫存活率下降。本研究表明,在室内条件下,以田间大纱笼作为半自然条件复壮的蠋蝽繁殖能力提高,但未复壮蠋蝽的F1代适应性更强。This study is aimed to address the degrade of quality during continuous rearing and improve the large-scale reproduction efficiency of the stinkbug Arma chinensis.The 4^(th) instar nymphs that had been reared continuously for 10 generations indoors were revitalized in gauze cages at semi natural conditions in the field.Biological characteristics,such as longevity of male and female adults,reproductive capacity,F1 generation development duration and survival rate,were measured in pairs of rejuvenated and/or non-rejuvenated stinkbugs (♀_(outdoor)×♂_(outdoor),♀_(outdoor)×♂_(indoor),♂_(outdoor)×♀_(indoor),♀_(indoor)×♂_(indoor)).Revitalization did not significantly affect the longevity of male and female adults,while significantly influenced the fertility and adaptability of F1 generation.♀_(indoor)×♂_(outdoor) group possessed the highest number of eggs,the shortest preoviposition period and the longest oviposition period.Compared with♀_(indoor)×♂_(outdoor )and♀_(indoor)×♂_(indoor),♀_(outdoor)×♂_(outdoor) and♀_(outdoor)×♂_(indoor) groups had reduced fertility and prolonged preoviposition period.There was no significant difference between the number of females and males in the♀_(indoor)×♂_(indoor) group,while the number of females in the♀_(indoor)×♂_(indoor) group was higher than that in the other groups (♀_(outdoor)×♂_(outdoor),♀_(outdoor)×♂_(indoor),♀_(indoor)×♂_(outdoor)).Compared with the♀_(indoor)×♂_(indoor) group,the development period from egg to adult in the♀_(outdoor)×♂_(outdoor )group was significantly prolonged,and the survival rate of adult was reduced in F1generation.This study shows that reproductive capacity of A.chinensis is improved when the stinkbug nymphsreproductive capacity of A.chinensis is improved when the stinkbug nymphs are rejuvenated in gauze cages at semi natural conditions in the field,while F1 generation of non-rejuvenating stinkbugs has strong adaptability.
