摘    要:美丽青背姬小蜂Chrysonotomyiaformosa(Westwood)是美洲斑潜蝇的优势天敌,在美洲 斑潜蝇的自然控制中发挥着非常重要的作用。本文对其生物学进行了研究,结果表明:在实验 温度范围内,随着温度的升高,寄生蜂羽化趋早,羽化时间更集中,羽化高峰也更明显;随着 温度的升高,成蜂的寿命逐渐缩短。在提供清水时,寄主可以显著地延长雌蜂的寿命;在有寄 主时,提供10%蜂蜜水,雌蜂的寿命显著延长。美丽青背姬小蜂对3龄寄主幼虫有偏好,对3龄寄 主幼虫的致死率和寄生率都高于对1~2龄寄主幼虫的,且产下后代的雌雄性比为5.11∶1。在 实验温度范围内,发育历期随温度的升高而缩短。

关 键 词:美丽青背姬小蜂  美洲斑潜蝇  生物学特性  寿命  发育历期

Abstract:Chrysonomyia formosa(Westwood) is a predominant parasitoid on the vegetable leafminer, Liriomyza sativae Blanchard. The bionomics of C. formosa was studied in the laboratory. With the increase of temperatures from 17℃ to 35℃, adult wasps emerged earlier, emergence time of adult was more concentrated, the peak of emergence advanced, and the longevity of the adults was shortened gradually. Feeding with water, the longevity of female was prolonged significantly when host larvae were provided than when host larvae not provided. Provided with host larvae the longevity of female wasp was prolonged significantly feeding on 10% honey liquid than those feeding on water. Female C. formosa preferred the 3rd instar larvae oL. sativae The mortality and parasitism on the 3rd instar larvae of host were higher than on the 1st instar and 2nd instar larvae. The sex ratio of offspring was 5.11(F) ∶ 1(M) when the 3rd instar larvae of host were offered for the female wasps. At the range of temperature 17℃ to 35℃, the developmental durations of the wasp were decreased with the increase of temperatures
Keywords:Chrysonotomyia formosa  Liriomyza sativae  biological characteristics  longevity  developmental duration
