| 中文摘要: |
| 眉斑并脊天牛 Glenea cantor Fabricius是我国华南地区园林绿化植物木棉树的重要蛀干害虫。本试验通过室内饲养观察和野外调查，对该虫的生物学特性进行了研究。结果表明该虫在南宁一年发生4代，平均世代历期为70 d，主要以4龄幼虫在受害枝干内越冬。成虫羽化后出木前期为5.97±1.11 d。雄虫较雌虫提早羽化2-3 d，成虫期需补充营养，且具弱趋光性和假死习性。在日节律中，9∶00-11∶00和14∶00-16∶00为产卵高峰期，16∶00-19∶00为交配高峰期。雌虫出木后2 d开始交配，雄虫出木后4 d开始交配。雌雄虫一生可交配15.12±7.02次，每次交配时长为3.23±0.97 h，一天内仅交配一次。成虫主要趋向长势较弱的木棉树及枝条上产卵。产卵前期为13.50±3.15 d，平均产卵量为117.31±33.25粒。雌雄寿命分别为72.34±15.60 d和46.22±14.38 d。 |

| Glenea cantorFabricius is an important stem borer of Gossampinus malbarica DC. in southern China. Biological characteristics of this species was studied through indoor rearing and field investigation. Results showed that G. cantorhad 4 generations a year in Nanning City, Guangxi Zhuang Autonomous Region, and mean generation duration was 70 d. G. cantorusually overwintered as the fourth instar larvae in host trunks or branches. Adults stayed in the pupal cells after eclosion for 5.97±1.11 d. Emergence of males was earlier than females for2-3 d. Both males and females displayed the behaviors of complementary nutrition, weak phototaxis, and suspended animation. The diel oviposition was observed from 9∶00 to 11∶00 a.m and from 14∶00 to 16∶00 p.m, and the diel mating between 16∶00 and 19∶00 p.m. Mating behavior of females was observed after emergence for 2 d, but that of males for 4 d. Mating times was 15.12±7.02 times during their life span. Both sexes ofG. cantormate only once a day, and each mating duration was 3.23±0.97 h. Females preferred the stems and branches of weak trees to oviposit. The preoviposition period was 13.50±3.15 d. Oviposition number of per female was 117.31±33.25. The average longevity of both female and male was 72.34±15.60 d and 46.22±14.38 d. |
