摘要:

班氏跳小蜂是我国外来入侵生物扶桑绵粉蚧的专性优势寄生蜂,其生物防治具有重要意义。本文首先采用不同温度和光周期对班氏跳小蜂的蛹进行不同时间的处理,探索最佳低温处理条件。然后在4 ℃低温下分别贮藏40、80、120、160、200、240、280、300 d,探索其最适低温贮藏时间。结果表明,班氏跳小蜂蛹期在温度为14 ℃、光周期(光照/黑暗)为8 h/16 h的条件下进行长达6 d的低温驯化,后于4 ℃冷藏80 d,将低温冷藏后的班氏跳小蜂在温度为26~28 ℃、相对湿度70%~80%、光周期为16 h/8 h的条件下进行培养,其效果与对照相当。此方法能为提高班氏跳小蜂的应用潜能提供技术支撑。

Abstract:

Aenasius bambawalei Hayat is an obligate dominant parasitoid of the invasive pest Phenacoccus solenopsis Tinsley in China, playing a significant role in biological control. This study firstly treated the pupae of Aenasius bambawalei Hayat with different temperatures and photoperiods for varying durations to explore optimal low temperature acclimation conditions. Subsequently, the pupae were stored at 4 ℃ for 40, 80, 120, 160, 200, 240, 280, 300 days to determine the optimal low temperature storage duration. The results showed that when the pupae were acclimated at 14 ℃ under a light/dark photoperiod of 8 h/16 h for 6 days, followed by refrigeration at 4 ℃ for 80 days, and then reared under conditions of 26-28 ℃, 70%-80% relative humidity, and a photoperiod of 16 h/8 h, their performance was equivalent to the control group. This method provides technical support for enhancing the application potential of Aenasius bambawalei Hayat.
