摘要: 为明确螺旋粉虱Aleurodicus dispersus作为繁育寄主对浅黄恩蚜小蜂Encarsia sophia发育适合度与控害能力的影响,本文以温室白粉虱Trialeurodes vaporariorum和烟粉虱Bemisia tabaci为寄主繁育的浅黄恩蚜小蜂为对照,评价了以螺旋粉虱为寄主所繁育的浅黄恩蚜小蜂雌蜂的个体大小、发育情况、高温寿命及对烟粉虱的控害能力。结果表明,与温室白粉虱和烟粉虱为寄主所繁育的浅黄恩蚜小蜂相比,以螺旋粉虱为寄主繁育的雌蜂个体更大、羽化率更高且发育历期最短,为13.0 d。以螺旋粉虱为寄主繁育的浅黄恩蚜小蜂对烟粉虱若虫的日均致死数为18.0头,显著高于温室白粉虱(13.5头)和烟粉虱(12.0头)繁育的浅黄恩蚜小蜂。此外,在32℃条件下螺旋粉虱繁育的雌蜂寿命为9.0 d,显著长于温室白粉虱(6.0 d)与烟粉虱(7.0 d)繁育的雌蜂寿命。研究结果为更高效地繁育与应用烟粉虱优势寄生蜂浅黄恩蚜小蜂奠定了基础。

Abstract: The developmental fitness and biocontrol potential of Encarsia sophia reared on Aleurodecus dispersus were measured, including the body size, developmental duration, emergence rate, longevity, and the control of Bemisia tabaci, with the wasps reared on Trialeurodes vaporariorum and B. tabaci as CK. The results showed larger body size, higher emergence rate, and shorter developmental duration (13.0 days) of the E. sophia females reared on A. dispersus than those reared on the other two hosts. The E. sophia females reared on A. disperses parasitized more B. tabaci nymphs (18.0 per day) than those females reared on T. vaporariorum and B. tabaci (13.5 and 12.0 per day, respectively). In addition, the longevity of the E. sophia females reared on A. disperses (9.0 days, at 32 ℃) was significantly greater than that of the E. sophia females reared on T. vaporariorum and B. tabaci (6.0 days and 7.0 days, respectively). The results are helpful for the efficient reproduction and application of E. sophia in the management of B. tabaci.
