中文摘要:

研究低温贮存椰心叶甲蛹Brontispa longissima (Gestro)和椰心叶甲僵蛹对椰心叶甲啮小蜂Tetrastichus brontispae Ferriere种群品质的影响。寄生10℃低温贮存1~4日龄椰心叶甲蛹结果表明,1日龄椰心叶甲蛹的寄生率、羽化率、出蜂率、单蛹出蜂数、后代寄生能力均优于其他日龄,其次为2、3日龄的椰心叶甲蛹,最差为4日龄的椰心叶甲蛹。1日龄椰心叶甲蛹在10℃下贮存5,10,15,20 d后,上述生物学指标和种群参数均随贮存天数增加而降低,其中以5 d 和10 d的净生殖率、内禀增长率和周限增长率较未经低温贮存的差异小。1~11日龄椰心叶甲僵蛹于10℃贮存10 d 的结果表明,8日龄椰心叶甲僵蛹的雌蜂寿命、羽化率、单蛹出蜂数、寄生能力均优于其他日龄僵蛹。8日龄椰心叶甲僵蛹在10℃下贮存5,10,15,20 d后,上述生物学指标和种群参数均随贮存天数增加而显著低于对照。

英文摘要:The present paper investigated the effect of cold storage of the Brontispa longissima (Gestro) pupae and parasitized B.longissima pupae on the population quality of Tetrastichus brontispae Ferriere.The 1~4 days old B.longissima pupae were stored at 10℃ for 10 days. Results showed that the highest parasitisation rate, highest emergence rates of per mummy, highest emergence rate,highest number of wasps per mummy and highest parasitic ability was found in 1 day old pupae,which was followed by that in 2~3 days pupae,while the lowest in 4 days old pupae. The 1 day old pupae biological qualities decreased as the period of cold storage increased from 5 days to 20 days,while the pupae cold storage 5 days and 10 days had no differences compared with the control.The mummies were stored at 10℃ for 10 days after they were formed 1~11 days. Results showed the longest adult life,highest highest emergence rates of per mummy,highest number of wasps per mummy and highest parasitic ability was found in 8 days mummies.The 8 days mummies biological qualities decreased significantly compared with the control as the period of cold storage increased from 5 days to 20 days.
