补充营养材料和温度对桉树枝瘿姬小蜂寿命的影响

摘要

Feeding experiments conducted with Leptocybe invasa Fisher & LaSalle females showed that food sources and temperature had significant effect on the longevity of the female.The longevity of the female was only (3.07 ±1.7) days without food source.Water, eucalyptus twigs and pollen suspension did not promote the longevity.20％ honey solution increased the longevity to more than 7 days, but honey of different sources(miscellaneous nectar honey/eucalyptus honey)had no significant promotion difference.In addition, in the range of 18～33 ℃, the longevity was prolonged at the beginning and shortened then with the temperature increasing.The optimal range of temperature was 18～27 ℃, the longest longevity of (8.18±3.54) days appeared at 21℃, and temperature above 30 ℃ shortened the longevity significantly.%室内试验结果表明,补充营养材料和温度对桉树枝瘿姬小蜂雌蜂存活时间具有显著影响.25℃条件下,无补充营养材料时,雌蜂的存活时间仅为(3.07±1.7)d,而清水、桉树嫩枝及花粉水均不能延长其寿命,但蜂蜜水能显著延长成虫存活时间至7d以上,且不同蜜源(杂花蜂蜜/桉树花蜂蜜)种类间无显著差异.此外,温度18～33℃范围内,随着温度的上升,桉树枝瘿姬小蜂雌虫存活时间先延长后缩短,21℃时,存活时间最长,可达8d.
