| 摘 要： | 在室内研究不同温度下对不同日龄的椰心叶甲啮小蜂处理不同时间对其寄生力的影响。结果表明,温度对椰心叶甲啮小蜂的雌雄性比并无明显影响。24~28℃时,椰心叶甲啮小蜂对椰心叶甲蛹的寄生力影响不明显,随着温度的降低,啮小蜂的寄生率、寄生蛹出蜂量明显下降。在一定温度范围内,较高的温度对椰心叶甲啮小蜂的寄生力有利。椰心叶甲啮小蜂在羽化交配后的1~4 d内寄生力没有明显变化,但随着日龄的增加,椰心叶甲啮小蜂的寄生力逐渐下降。椰心叶甲啮小蜂成蜂在不同温度下贮藏1~3 d时对其品质影响不大,贮藏4 d后其寄生力急剧下降。

| Abstract: | The influences of temperature on the parasitic ability of Tetrastichus brontispae Ferrière with various ages were studied in the laboratory.The results showed that temperature had no significant influence on the sex ratio of T.brontispae.The parasitic ability of T.brontispae to the pupae of coconut leaf beetle Brontispa longissima(Gestro) was not markedly effected by the temperature of 24~28 ℃,while when the temperature decreased further,the parasitic rate of T.brontispae and the quantity of T.brontispae co... |
