影响榕小蜂性比的相关研究

Studies Related to the Influence of Sex Ratios in Fig Wasps

榕小蜂是检验局域交配竞争和近交条件下性比调节机制的模式动物,可分为传粉榕小蜂与非传粉榕小蜂两大体系。榕小蜂的自然种群中雌雄异体,性比失调是一个客观现象。不同的交配产卵方式、小蜂的性别决定系统、种群中局域配偶竞争关系、近交、窝卵数和固定雄性卵均对性比产生影响,说明性比失调影响因素复杂,具有综合性。本文总结影响榕小蜂性比的相关研究,以期更加全面合理地揭示榕小蜂性比变化规律。

Fig wasps are a model animal for examining the mechanisms of sex ratio regulation under local mating competition and inbreeding conditions,where they can be divided into two systems:pollinating and non-pollinating Fig wasps.Different mating and laying modes,sex determination system,local mate competition,inbreeding,brood size and fixed male eggs all affect the sex ratio,suggesting that the factors affecting sex ratio disorders are complex and comprehensive.This paper summarise relevant studies on the sex ratio of Fig wasps in order to provide a more comprehensive and rational picture of the variation of sex ratio in Fig wasps.
