摘　　要：针对蠋蝽规模化繁育中成虫配对期食物的优化,研究了黏虫蛹和黄粉虫蛹低温保藏后的存活率及其作为配对期食物对蠋蝽产卵的影响。结果表明,黄粉虫蛹和黏虫蛹在6℃保藏30 d后的存活率分别为89.33%、22.67%;蠋蝽配对期以冷藏黄粉虫蛹为食物,其总产卵量、单次平均产卵量、孵化率均显著高于以冷藏黏虫蛹为食物;蠋蝽对冷藏黄粉虫蛹的捕食偏好高于冷藏黏虫蛹。以冷藏的黄粉虫蛹作为配对期食物对提高蠋蝽人工扩繁效率具有重要意义。In order to optimize the diet of Armachinensis during its mating period in large-scale breeding,the oviposition of Armachinensis when provided with pupa of Mythimna separate and Tenebriomolitor as diet was evaluated.In addition,the pupa survival rate of M.separate and T.molitor after cryopreservation was investigated.The results showed that after cryopreservation at 6℃for 30 days,the pupa survival rates of M.separate and T.molitor were 89.33%and 22.67%,respectively.The total and average oviposition amount,and the hatchability of A.chinensis fed on refrigerated T.molitor pupae were significantly higher than those fed on refrigerated M.separate pupae during mating period.Armachinensis had higher predation preference for refrigerated pupae of T.molitor than M.separata.The pupae of T.molitor stored at low temperature could be an important diet to improve the efficiency of artificial propagation for A.chinensis during its mating period.
