研究了采自伊朗不同害虫的两种广赤眼蜂种群(T.evanescens A和T.evanescens B)的滞育,在米蛾卵内用恒温8℃,5℃或变温(11-23)℃-11℃容易地诱导T.evanescens A进入稳定的滞育,但却不能用同样的温度和寄主诱导T.evanescens B进入滞育.试验表明,母代的寄主和避免复寄生的能力可能在广赤眼蜂滞育诱导种内变异中起重要作用.
The diapause of T.evanescens A and T.evanescens B from different pests of Iranian pests was studied. The diapause was induced in the rice moth by constant temperature 8 ℃, 5 ℃ or variable temperature (11-23) ℃ -11 ° C easily induced T.evanescens A into stable diapause but did not enter diapause with the same temperature and host-induced T.evanescens B. The experiments showed that the parental host and the ability to avoid parasitism may be broad Trichogramma diapause induced intraspecific variation plays an important role.
